Class StrTokCmpr


  • public class StrTokCmpr
    extends java.lang.Object
    Similar to class String-Compare, String-Token-Compare also provides an exhaustive suite of methods that extend the basic Java String methods equals, contains, startsWith and endsWith, but further allowing a user to specify the match-string boundary-characters.

    This class is identical to class StrCmpr - save one primary difference. The substrings that are tested must be surrounded by white-space, or by a specified character-delimiter test, before the comparison logic considers them to have matched.

    StrTokCmpr =>

    1. StrTok: Token-Matches are substring matches which are found inside a supplied 'srcStr'. These matches must be both fully contained within 'srcStr', and have "match locations" (String-index position in 'srcStr' where the token matches) that are bounded / 'surrounded' by either white-space (space-character '#32', '\n', '\r', etc ) or by characters that pass a user supplied Character-Predicate test().
    2. Cmpr: Each of the methods in this class shall return an boolean that indicates whether the input 'srcStr' matches the method's query-specifications. The various queries in this class are based on the presence or absence of a particular String (parameter 'token(s)') being inside another Source-String (parameter 'srcString').

    Methods Available

    Method-Name Key-Word Explanation
    NAND May not find any matches between the primary String srcStr parameter, and the String's in String... tokens

    NAND-NOTE: There is one very important subtlety about the meaning of 'NAND' here. In this case, the methods that use 'NAND' interpret its meaning as "NOT ANY ONE OF..." - meaning all comparisons must fail.
    XOR Must find precisely one match between the primary String srcStr parameter, and the String's in String... tokens.

    There is one 'philosophical note' which is that if multiple copies of an identical-String are passed via the comparison-Stringarray (String... tokens), all XOR methods shall not pay heed to the notion that they the 'srcStr' parameter may have only started-with, ended-with or contained a single String (and 'philosophically passing' the XOR, one-and-only-one test). The internal-logical is 'programmatically ignorant' of this - multiple copies of an identical-String (or identical, ignoring-case) could theoretically be flagged via throwing an IllegalArgumentException. However, no such check is performed.
    OR Must find at least one match between the primary String srcStr parameter, and the String's in the 'tokens' parameter.
    AND Must identify a containing-match between each and every String in String... tokens and the primary 'srcStr' parameter.
    Starts With The provided token-String must match each character at the beginning of the String-parameter 'srcStr'. Furthermore, the character immediately after the token-String in 'srcStr' must be either:

    • White-space (matching '\s')
    • String-terminus (matching '$')
    • In situations where an extraDelimiterTest has been passed to the method, characters that receive TRUE from the invokation of the Character-Predicate's test(char) method shall also be considered for a 'Token-Match'.
    Ends With The provided token-String must match each character at the ending of the String-parameter 'srcStr'. Furthermore, the character directly before the token-String in 'srcStr' must be either:

    • White-space (matching '\s')
    • String-start (matching '^')
    • In situations where an extraDelimiterTest has been passed to the method, characters that receive TRUE from the invokation of the Character-Predicate's test(char) method shall also be considered for a 'Token-Match'.
    Contains The provided token-String must be a substring of the String-parameter 'srcStr'. Furthermore, the characters directly before and immediately following the token-String match location in 'srcStr' must assume one of the following values:

    • White-space (matching '\s')
    • String-start (matching '^')
    • String-terminus (matching '$')
    • In situations where an extraDelimiterTest has been passed to the method, characters that receive TRUE from the invokation of the Character-Predicate's test(char) method shall also be considered for a 'Token-Match'.
    CI (Case Insensitive) All equality-tests will be done on a Case Insensitive basis.

    Method Parameters

    Parameter Explanation
    String srcStr This parameter is mandatory for every method here. It is the source String that is being searched. Every method is designed to iterate through the characters in this String, searching for matches of token(s).
    int nth This represents the 'nth' match of a comparison for-loop. When the method-signature used includes the parameter 'nth' , the first n-1 matches that are found - will be skipped, and the 'nth' match is, instead, returned.

    EXCEPTIONS: An NException shall throw if the value of parameter 'nth' is zero, negative, or larger than the size of the input html-Vector.
    int sPos, int ePos When these parameters are present, only substring's that are found between these specified String indices will be considered when returning results from StrTokIndexOf.

    NOTE: In every situation where the parameters int sPos, int ePos are used, parameter 'ePos' will accept a negative value, but parameter 'sPos' will not. When 'ePos' is passed a negative-value, the internal LV ('Loop Variable Counter') will have its public final int end field set to the length of the 'srcStr' parameter String.

    EXCEPTIONS: An IndexOutOfBoundsException will be thrown if:

    • If sPos is negative, or if sPos is greater-than or equal-to the size of 'srcStr'
    • If ePos is zero, or greater than the size 'srcStr'.
    • If sPos is a larger integer than ePos
    String token This is the testing-substring that is this class' search goal. When this String is identified as a substring of the input-parameter String 'srcStr', a potential match has been found. In order for potential matches to be returned as results, they are subsequently tested for surrounding white-space (or the additional 'extraDelimiterTest'). The requirements for a potential match to be returned as a Token Match are as follows:

    • The location of 'token' in 'srcStr' must be bounded by white-space, or be located at the very beginning or ending of the 'srcStr'.
    • If an extraDelimiterTest has been provided, the location of 'token' in 'srcStr' may also be bounded by characters that are a match with the Character-Predicate 'test(char)' method.
    • And, of course, the 'token' must be a substring of 'srcStr'
    String... tokens Each of the 'token' String's passed using Varargs array parameter 'tokens' must follow the exact same rules explained in the previous parameter entry (directly above) in order to be considered token-matches with/for input parameter 'srcStr'. All the Varargs String-Array adds is that it facilitates testing multiple tokens all at the same time so that their comparison-results can be AND'ed, OR'ed, NAND'ed, etc...
    Predicate<Character> extraDelimiterTest When this parameter is present in the method-signature parameter-list, the decision of whether a Token-Match is to be included in the search result-set can be made less restrictive. Usually, a match must be delimited by white-space; meaning that the characters directly before and after the match location in 'srcStr' must be white-space, or the String terminus (Regex: '^' and '$').

    However, when this parameter is part of a method signature, the method body in this class that implements this search will also permit a token-match location to be bounded by characters that pass this Character-Predicate's Predicate.test(char) method.

    For instance, if (Character c) -> ",.!?()".contains("" + c) were passed to this parameter, then: commas, periods, exclamation-points, question-marks, and parenthesis would all be allowed directly before or immediately after the token-match location of the 'token' parameter inside String 'srcStr'.


Stateless Class: This class neither contains any program-state, nor can it be instantiated. The @StaticFunctional Annotation may also be called 'The Spaghetti Report'. Static-Functional classes are, essentially, C-Styled Files, without any constructors or non-static member field. It is very similar to the Java-Bean @Stateless Annotation.

      • DEBUG

        🡇    
        public static boolean DEBUG
        Utility field. You may choose to set this variable to true, and the following String commands will print to an internally stored Consumer<String> DEBUG_LOG class that may be set. This is generally a very minor drain on code-efficiency. When this flag is set to FALSE, a short if-statement evaluation still occurs even when the flag is false on each occasion that the string-comparison loops identify and return a match. This is very minor performance loss, and does provide quite a lot of help to those trying to identify difficult to notice problems with partial-String comparisons.

        IMPORTANT: In order to use this minor debugging feature, it is necessary to provide a Consumer<String> DEBUG_LOG to the public static field! If this field is not set to a valid, non-null object-reference, then this class will through a NullPointerException on its first attempt to compare strings. This String-consumer may do anything it wants with the debug-String information.

        FORMAT: The output string format is just:
         private static void PRNT(String methodName, String srcStr, String token)
         { DEBUG_LOG.accept(methodName + "-MATCH[" + srcStr + ", " + token + "] "); }
        

        Generally, you would want to use a simple lambda such as:

        Example:
         StrCmpr.DEBUG_LOG = (String logInfoStr) -> System.out.println(logInfoStr);
        


        FINALLY: If you are logging, please note that any of the methods whose name ends with the phrase "IgnoreCase" will not contribute (print) to the log. this is primarily because these are all single-argument comparisons, and logging would be of only minor benefit. The primary benefit of a debug-log is the ability to identify which/when a particular substring from a list of substrings actually matched. The methods whose names contain the two letter acronym "_CI" are all "Case Insensitive" - and they also do comparisons to multiple-input var-args String parameters.

      • DEBUG_LOG

        🡅  🡇    
        public static java.util.function.Consumer<java.lang.String> DEBUG_LOG
        This object reference cannot be null when DEBUG is TRUE. This StorageWriter will receive text-notifications every time the string-comparing loops identify a match.

        IMPORTANT: No attempt has been made to ensure that this debugging feature will operate perfectly in a multi-threaded environment. The two reasons for this are:

        1. The primary purpose of this LOG is for debugging code, not putting details about string-match information into an 'on-line' or production environment.
        2. This is a best-efforts string-comparison package that would sacrifice quite a bit of its utility if it were expected to maintain multiple instances of this class just to have StrCmpr debug operations work in multiple-threads. Code readability necessitates keeping this a class with only static methods.
        3. Two threads making calls to this class StrCmpr might see log-writes that, sadly, look like they 'interlaced' (crashed), but even when this occasions, reading the log wouldn't be that difficult anyway.

        Checks to ensure that parameter 'srcStr' does not start with any of the tokens supplied by the 'tokens' array.

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of java.lang.String
        tokens - The String's used in the comparison against 'srcStr'

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match within String parameter 'srcStr' that begins at srcStr.charAt(0), it will check the character directly after that match in order to ensure that it assumes only one of these two values:

        white-space (matching '\s')
        String-terminus (matching '$')
        Returns:
        TRUE if 'srcStr' does not start with any of the user-provided tokens. Matches are only taken into consideration if they are delimited appropriately. Token-Matches are sufficient, while Sub-String-Matches are not.

        Parameters:
        srcStr - Any non-null instance of java.lang.String
        tokens - The String's used in the comparison against 'srcStr'

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match anywhere within String parameter 'srcStr', it will check both the character immediately preceding and the character directly after that match in order to ensure that they assume only one of these three values:

        white-space (matching '\s')
        String-start (matching '^')
        String-terminus (matching '$')
        sPos - This is the integer-index String-location which limits the left-most position to search in 'srcStr'. This value is 'inclusive,' meaning that if the character at this index (in 'srcStr') is part of a match, it shall be factored into the return results. Note that if this value is negative, or larger than the length of 'srcStr', an exception will be thrown.
        ePos - This is the integer-index String-location which limits the right-most position to search in 'srcStr'. This value is 'exclusive,' meaning that if the character at this location is part of match, it will not be calculated into the results. If this value is larger than the length of input-parameter 'srcStr', an exception will throw.

        NOTE: Passing a negative value to this parameter, 'ePos', will cause its to be reset to the integer-value: srcStr.length()
        Returns:
        TRUE if the Sub-String consisting of the characters inside 'srcStr', between sPos and ePos contains at least one of the user-provided tokens. Matches are only taken into consideration if they are delimited appropriately. Token-Matches are sufficient, while Sub-String-Matches are not.
        Throws:
        java.lang.StringIndexOutOfBoundsException - This exception shall be thrown if any of the following are true:

        • If 'sPos' is negative, or if sPos is greater-than-or-equal-to the length of the String
        • If 'ePos' is zero, or greater than the length of the String

If this value is larger than the length of input-parameter 'srcStr', an exception will throw.

        NOTE: Passing a negative value to this parameter, 'ePos', will cause its to be reset to the integer-value: srcStr.length()
        Returns:
        TRUE if the Sub-String consisting of the characters inside 'srcStr', between sPos and ePos contains every one of the user-provided tokens. Matches are only taken into consideration if they are delimited appropriately. Token-Matches are sufficient, while Sub-String-Matches are not.

                                          java.lang.String... tokens)
        Checks to ensure that the 'srcStr' substring, which is demarcated by 'sPos' (inclusive) and 'ePos' (exclusive), contains exactly one of the tokens supplied by the 'tokens' array.

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of java.lang.String
        tokens - The String's used in the comparison against 'srcStr'

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match anywhere within String parameter 'srcStr', it will check both the character immediately preceding and the character directly after that match in order to ensure that they assume only one of these three values:

        white-space (matching '\s')
        String-start (matching '^')
        String-terminus (matching '$')
        sPos - This is the integer-index String-location which limits the left-most position to search in 'srcStr'. This value is 'inclusive,' meaning that if the character at this index (in 'srcStr') is part of a match, it shall be factored into the return results. Note that if this value is negative, or larger than the length of 'srcStr', an exception will be thrown.
        ePos - This is the integer-index String-location which limits the right-most position to search in 'srcStr'. This value is 'exclusive,' meaning that if the character at this location is part of match, it will not be calculated into the results. If this value is larger than the length of input-parameter 'srcStr', an exception will throw.

        NOTE: Passing a negative value to this parameter, 'ePos', will cause its to be reset to the integer-value: srcStr.length()
        Returns:
        TRUE if the Sub-String consisting of the characters inside 'srcStr', between sPos and ePos contains exactly one of the user-provided tokens. Matches are only taken into consideration if they are delimited appropriately. Token-Matches are sufficient, while Sub-String-Matches are not.
        Throws:
        java.lang.StringIndexOutOfBoundsException - This exception shall be thrown if any of the following are true:

        • If 'sPos' is negative, or if sPos is greater-than-or-equal-to the length of the String
        • If 'ePos' is zero, or greater than the length of the String
        • If the value of 'sPos' is a larger integer than 'ePos'. If ePos was negative, it is first reset to String.length(), before this check is done.

                                            java.lang.String... tokens)
        Checks to ensure that the 'srcStr' substring, which is demarcated by 'sPos' (inclusive) and 'ePos' (exclusive), starts with exactly one of the tokens supplied by the 'tokens' array.

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of java.lang.String
        tokens - The String's used in the comparison against 'srcStr'

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match within String parameter 'srcStr' that begins at srcStr.charAt(0), it will check the character directly after that match in order to ensure that it assumes only one of these two values:

        white-space (matching '\s')
        String-terminus (matching '$')
        sPos - This is the integer-index String-location which limits the left-most position to search in 'srcStr'. This value is 'inclusive,' meaning that if the character at this index (in 'srcStr') is part of a match, it shall be factored into the return results. Note that if this value is negative, or larger than the length of 'srcStr', an exception will be thrown.
        ePos - This is the integer-index String-location which limits the right-most position to search in 'srcStr'. This value is 'exclusive,' meaning that if the character at this location is part of match, it will not be calculated into the results. If this value is larger than the length of input-parameter 'srcStr', an exception will throw.

        NOTE: Passing a negative value to this parameter, 'ePos', will cause its to be reset to the integer-value: srcStr.length()
        Returns:
        TRUE if the Sub-String consisting of the characters inside 'srcStr', between sPos and ePos starts with exactly one of the user-provided tokens. Matches are only taken into consideration if they are delimited appropriately. Token-Matches are sufficient, while Sub-String-Matches are not.
        Throws:
        java.lang.StringIndexOutOfBoundsException - This exception shall be thrown if any of the following are true:

        • If 'sPos' is negative, or if sPos is greater-than-or-equal-to the length of the String
        • If 'ePos' is zero, or greater than the length of the String
        • If the value of 'sPos' is a larger integer than 'ePos'. If ePos was negative, it is first reset to String.length(), before this check is done.

        String-terminus (matching '$')
        Returns:
        TRUE if the Sub-String consisting of the characters inside 'srcStr', between sPos and ePos starts with the specified token. A match is only taken into consideration if it is delimited appropriately. A Token-Match is sufficient, while a Sub-String-Match is not.
        Throws:
        java.lang.StringIndexOutOfBoundsException - This exception shall be thrown if any of the following are true:

        • If 'sPos' is negative, or if sPos is greater-than-or-equal-to the length of the String
        • If 'ePos' is zero, or greater than the length of the String
        • If the value of 'sPos' is a larger integer than 'ePos'. If ePos was negative, it is first reset to String.length(), before this check is done.

        Checks whether or not a substring of 'srcStr' ends with the 'compareStr' token. The substring that is checked is demarcated by 'sPos' (inclusive), and 'ePos' (exclusive).

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of java.lang.String
        sPos - This is the integer-index String-location which limits the left-most position to search in 'srcStr'. This value is 'inclusive,' meaning that if the character at this index (in 'srcStr') is part of a match, it shall be factored into the return results. Note that if this value is negative, or larger than the length of 'srcStr', an exception will be thrown.
        ePos - This is the integer-index String-location which limits the right-most position to search in 'srcStr'. This value is 'exclusive,' meaning that if the character at this location is part of match, it will not be calculated into the results. If this value is larger than the length of input-parameter 'srcStr', an exception will throw.

        NOTE: Passing a negative value to this parameter, 'ePos', will cause its to be reset to the integer-value: srcStr.length()
        token - The String used in the comparison against srcStr

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match within String parameter 'srcStr' that ends at srcStr.charAt(srcStr.length() - 1), it will check the character immediately preceding that match in order to ensure that it assumes only one of these two values:

        white-space (matching '\s')
        String-start (matching '^')
        Returns:
        TRUE if the Sub-String consisting of the characters inside 'srcStr', between sPos and ePos ends with the specified token. A match is only taken into consideration if it is delimited appropriately. A Token-Match is sufficient, while a Sub-String-Match is not.
        Throws:

        Implementing a 'contains' is more efficient by performing only one loop iteration. Therefore, the methods that implement some variant of the String.contains method will use this general-purpose contains-testing method.
        Parameters:
        ignoresCase - This is used to signify whether to ignore case when performing the String-comparison operations.
        booleanOperation - This is designed to take one of four values. This method will throw an exception if it does not.
        l - Loop end-point parameter
        srcStr - Any non-null instance of java.lang.String
        tokens - This is one (or many) java String's, each of which shall be checked whether it is contained by 'srcStr'.
        Returns:
        The appropriate response based on the inputs for boolean logic.
        Code:
        Exact Method Body:
         int     len         = srcStr.length();

        Implementing a 'contains' is more efficient by performing only one loop iteration. Therefore, the methods that implement some variant of the String.contains method will use this general-purpose contains-testing method.
        Parameters:
        ignoresCase - This is used to signify whether to ignore case when performing the String-comparison operations.
        booleanOperation - This is designed to take one of four values. This method will throw an exception if it does not.
        srcStr - Any non-null instance of java.lang.String
        tokens - This is one (or many) java String's, each of which shall be checked whether it is contained by 'srcStr'.
        Returns:
        The appropriate response based on the inputs for boolean logic.
        Code:

        Checks to ensure that parameter 'srcStr' contains at least one of the tokens supplied by the 'tokens' array.

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of java.lang.String
        extraDelimiterTest - Can be used if characters other than white-space should be considered as token-delimiters. Useful CharPredicate's to this parameter are, for example, tests to further allow punctuation - commas, periods, parenthesis, etc... as match boundaries.

        Useful Predicate's to provide might include (but are not limited to) the following:

        Character::isSpaceChar (includes UNICODE White-Space)
        Character::isDigit
        c -> ".,:;!?()".contains(c) (Miscellaneous Punctuation)
        Any character test of your choosing
        tokens - The String's used in the comparison against 'srcStr'

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match anywhere within String parameter 'srcStr', it will check both the character immediately preceding and the character directly after that match in order to ensure that they assume only one of these four values:

        white-space (matching '\s')
        String-start (matching '^')
        String-terminus (matching '$')
        any character which passes the parameter-provided Predicate<Character> delimiter test
        Returns:
        TRUE if 'srcStr' contains at least one of the user-provided tokens. Matches are only taken into consideration if they are delimited appropriately. Token-Matches are sufficient, while Sub-String-Matches are not.

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match anywhere within String parameter 'srcStr', it will check both the character immediately preceding and the character directly after that match in order to ensure that they assume only one of these four values:

        white-space (matching '\s')
        String-start (matching '^')
        String-terminus (matching '$')
        any character which passes the parameter-provided Predicate<Character> delimiter test
        Returns:
        TRUE if 'srcStr' contains exactly one of the user-provided tokens. Matches are only taken into consideration if they are delimited appropriately. Token-Matches are sufficient, while Sub-String-Matches are not.

                     java.lang.String token)
        
        Checks to ensure that 'srcStr' ends with the 'compareStr' token.

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of java.lang.String
        extraDelimiterTest - Can be used if characters other than white-space should be considered as token-delimiters. Useful CharPredicate's to this parameter are, for example, tests to further allow punctuation - commas, periods, parenthesis, etc... as match boundaries.

        Useful Predicate's to provide might include (but are not limited to) the following:

        Character::isSpaceChar (includes UNICODE White-Space)
        Character::isDigit
        c -> ".,:;!?()".contains(c) (Miscellaneous Punctuation)
        Any character test of your choosing
        token - The String used in the comparison against srcStr

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match within String parameter 'srcStr' that ends at srcStr.charAt(srcStr.length() - 1), it will check the character immediately preceding that match in order to ensure that it assumes only one of these three values:

        white-space (matching '\s')
        String-start (matching '^')
        any character which passes the parameter-provided Predicate<Character> delimiter test
        Returns:
        TRUE if 'srcStr' ends with the specified token. A match is only taken into consideration if it is delimited appropriately. A Token-Match is sufficient, while a Sub-String-Match is not.
        Code:
        Exact Method Body:
         int tokenLen = token.length();
        
         return  srcStr.endsWith(token)
                 &&  (   ((srcStr.length() - tokenLen) == 0)

        Parameters:
        srcStr - Any non-null instance of java.lang.String
        sPos - This is the integer-index String-location which limits the left-most position to search in 'srcStr'. This value is 'inclusive,' meaning that if the character at this index (in 'srcStr') is part of a match, it shall be factored into the return results. Note that if this value is negative, or larger than the length of 'srcStr', an exception will be thrown.
        ePos - This is the integer-index String-location which limits the right-most position to search in 'srcStr'. This value is 'exclusive,' meaning that if the character at this location is part of match, it will not be calculated into the results. If this value is larger than the length of input-parameter 'srcStr', an exception will throw.

        NOTE: Passing a negative value to this parameter, 'ePos', will cause its to be reset to the integer-value: srcStr.length()
        extraDelimiterTest - Can be used if characters other than white-space should be considered as token-delimiters. Useful CharPredicate's to this parameter are, for example, tests to further allow punctuation - commas, periods, parenthesis, etc... as match boundaries.

        String-start (matching '^')
        String-terminus (matching '$')
        any character which passes the parameter-provided Predicate<Character> delimiter test
        Returns:
        TRUE if the Sub-String consisting of the characters inside 'srcStr', between sPos and ePos contains at least one of the user-provided tokens. Matches are only taken into consideration if they are delimited appropriately. Token-Matches are sufficient, while Sub-String-Matches are not.
        Throws:
        java.lang.StringIndexOutOfBoundsException - This exception shall be thrown if any of the following are true:

        • If 'sPos' is negative, or if sPos is greater-than-or-equal-to the length of the String
        • If 'ePos' is zero, or greater than the length of the String

                     int sPos,
                     int ePos,
                     java.util.function.Predicate<java.lang.Character> extraDelimiterTest,
                     java.lang.String... tokens)
        
        Checks to ensure that the 'srcStr' substring, which is demarcated by 'sPos' (inclusive) and 'ePos' (exclusive), does not contain any of the tokens supplied by the 'tokens' array.

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of java.lang.String
        sPos - This is the integer-index String-location which limits the left-most position to search in 'srcStr'. This value is 'inclusive,' meaning that if the character at this index (in 'srcStr') is part of a match, it shall be factored into the return results. Note that if this value is negative, or larger than the length of 'srcStr', an exception will be thrown.
        ePos - This is the integer-index String-location which limits the right-most position to search in 'srcStr'. This value is 'exclusive,' meaning that if the character at this location is part of match, it will not be calculated into the results. If this value is larger than the length of input-parameter 'srcStr', an exception will throw.

        NOTE: Passing a negative value to this parameter, 'ePos', will cause its to be reset to the integer-value: srcStr.length()
        extraDelimiterTest - Can be used if characters other than white-space should be considered as token-delimiters. Useful CharPredicate's to this parameter are, for example, tests to further allow punctuation - commas, periods, parenthesis, etc... as match boundaries.

        Useful Predicate's to provide might include (but are not limited to) the following:

        Character::isSpaceChar (includes UNICODE White-Space)
        Character::isDigit
        c -> ".,:;!?()".contains(c) (Miscellaneous Punctuation)
        Any character test of your choosing
        tokens - The String's used in the comparison against 'srcStr'

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match anywhere within String parameter 'srcStr', it will check both the character immediately preceding and the character directly after that match in order to ensure that they assume only one of these four values:

        white-space (matching '\s')
        String-start (matching '^')
        String-terminus (matching '$')
        any character which passes the parameter-provided Predicate<Character> delimiter test
        Returns:
        TRUE if the Sub-String consisting of the characters inside 'srcStr', between sPos and ePos does not contain any of the user-provided tokens. Matches are only taken into consideration if they are delimited appropriately. Token-Matches are sufficient, while Sub-String-Matches are not.
        Throws:
        java.lang.StringIndexOutOfBoundsException - This exception shall be thrown if any of the following are true:

        • If 'sPos' is negative, or if sPos is greater-than-or-equal-to the length of the String
        • If 'ePos' is zero, or greater than the length of the String
        • If the value of 'sPos' is a larger integer than 'ePos'. If ePos was negative, it is first reset to String.length(), before this check is done.

        tokens - The String's used in the comparison against 'srcStr'

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match within String parameter 'srcStr' that ends at srcStr.charAt(srcStr.length() - 1), it will check the character immediately preceding that match in order to ensure that it assumes only one of these three values:

        white-space (matching '\s')
        String-start (matching '^')
        any character which passes the parameter-provided Predicate<Character> delimiter test
        Returns:
        TRUE if the Sub-String consisting of the characters inside 'srcStr', between sPos and ePos does not end with any of the user-provided tokens. Matches are only taken into consideration if they are delimited appropriately. Token-Matches are sufficient, while Sub-String-Matches are not.
        Throws:
        java.lang.StringIndexOutOfBoundsException - This exception shall be thrown if any of the following are true:

        • If 'sPos' is negative, or if sPos is greater-than-or-equal-to the length of the String
        • If 'ePos' is zero, or greater than the length of the String
        • If the value of 'sPos' is a larger integer than 'ePos'. If ePos was negative, it is first reset to String.length(), before this check is done.

        Checks to ensure that the 'srcStr' substring, which is demarcated by 'sPos' (inclusive) and 'ePos' (exclusive), starts with exactly one of the tokens supplied by the 'tokens' array.

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of java.lang.String
        sPos - This is the integer-index String-location which limits the left-most position to search in 'srcStr'. This value is 'inclusive,' meaning that if the character at this index (in 'srcStr') is part of a match, it shall be factored into the return results. Note that if this value is negative, or larger than the length of 'srcStr', an exception will be thrown.
        ePos - This is the integer-index String-location which limits the right-most position to search in 'srcStr'. This value is 'exclusive,' meaning that if the character at this location is part of match, it will not be calculated into the results. If this value is larger than the length of input-parameter 'srcStr', an exception will throw.

        NOTE: Passing a negative value to this parameter, 'ePos', will cause its to be reset to the integer-value: srcStr.length()
        extraDelimiterTest - Can be used if characters other than white-space should be considered as token-delimiters. Useful CharPredicate's to this parameter are, for example, tests to further allow punctuation - commas, periods, parenthesis, etc... as match boundaries.

        Useful Predicate's to provide might include (but are not limited to) the following:

        Character::isSpaceChar (includes UNICODE White-Space)
        Character::isDigit
        c -> ".,:;!?()".contains(c) (Miscellaneous Punctuation)
        Any character test of your choosing
        tokens - The String's used in the comparison against 'srcStr'

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match within String parameter 'srcStr' that begins at srcStr.charAt(0), it will check the character directly after that match in order to ensure that it assumes only one of these three values:

        white-space (matching '\s')
        String-terminus (matching '$')
        any character which passes the parameter-provided Predicate<Character> delimiter test
        Returns:
        TRUE if the Sub-String consisting of the characters inside 'srcStr', between sPos and ePos starts with exactly one of the user-provided tokens. Matches are only taken into consideration if they are delimited appropriately. Token-Matches are sufficient, while Sub-String-Matches are not.
        Throws:

        Checks whether or not a substring of 'srcStr' starts with the 'compareStr' token. The substring that is checked is demarcated by 'sPos' (inclusive), and 'ePos' (exclusive).

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of java.lang.String
        sPos - This is the integer-index String-location which limits the left-most position to search in 'srcStr'. This value is 'inclusive,' meaning that if the character at this index (in 'srcStr') is part of a match, it shall be factored into the return results. Note that if this value is negative, or larger than the length of 'srcStr', an exception will be thrown.
        ePos - This is the integer-index String-location which limits the right-most position to search in 'srcStr'. This value is 'exclusive,' meaning that if the character at this location is part of match, it will not be calculated into the results. If this value is larger than the length of input-parameter 'srcStr', an exception will throw.

        NOTE: Passing a negative value to this parameter, 'ePos', will cause its to be reset to the integer-value: srcStr.length()
        extraDelimiterTest - Can be used if characters other than white-space should be considered as token-delimiters. Useful CharPredicate's to this parameter are, for example, tests to further allow punctuation - commas, periods, parenthesis, etc... as match boundaries.

        Useful Predicate's to provide might include (but are not limited to) the following:

        Character::isSpaceChar (includes UNICODE White-Space)
        Character::isDigit
        c -> ".,:;!?()".contains(c) (Miscellaneous Punctuation)
        Any character test of your choosing
        token - The String used in the comparison against srcStr

        When this method makes token comparisons using the input String-token parameter(s), if the logic finds a match within String parameter 'srcStr' that begins at srcStr.charAt(0), it will check the character directly after that match in order to ensure that it assumes only one of these three values:

        white-space (matching '\s')
        String-terminus (matching '$')
        any character which passes the parameter-provided Predicate<Character> delimiter test
        Returns:
        TRUE if the Sub-String consisting of the characters inside 'srcStr', between sPos and ePos starts with the specified token. A match is only taken into consideration if it is delimited appropriately. A Token-Match is sufficient, while a Sub-String-Match is not.
        Throws:
        java.lang.StringIndexOutOfBoundsException - This exception shall be thrown if any of the following are true:

        • If 'sPos' is negative, or if sPos is greater-than-or-equal-to the length of the String
        • If 'ePos' is zero, or greater than the length of the String
        • If the value of 'sPos' is a larger integer than 'ePos'. If ePos was negative, it is first reset to String.length(), before this check is done.

        Implementing a 'contains' is more efficient by performing only one loop iteration. Therefore, the methods that implement some variant of the String.contains method will use this general-purpose contains-testing method.
        Parameters:
        ignoresCase - This is used to signify whether to ignore case when performing the String-comparison operations.
        booleanOperation - This is designed to take one of four values. This method will throw an exception if it does not.
        l - Loop end-point parameter
        srcStr - Any non-null instance of java.lang.String
        extraDelimiterTest - Can be used if characters other than white-space should be considered as token-delimiters. Useful CharPredicate's to this parameter are, for example, tests to further allow punctuation - commas, periods, parenthesis, etc... as match boundaries.

        Useful Predicate's to provide might include (but are not limited to) the following:

        Character::isSpaceChar (includes UNICODE White-Space)
        Character::isDigit
        c -> ".,:;!?()".contains(c) (Miscellaneous Punctuation)
        Any character test of your choosing
        tokens - This is one (or many) java String's, each of which shall be checked whether it is contained by 'srcStr'.
        Returns:
