Class StrCmpr


  • public class StrCmpr
    extends java.lang.Object
    Class String-Compare provides an exhaustive-combinatoric suite of methods that extend the basic Java String methods equals, contains, startsWith and endsWith.

    This class offers an API that has a large collection of comparison routines for a java.lang.String.

    Obviously, Regular-Expressions will always be capable of providing the most powerful String-Search and manipulations routines. However, with the extra level of control that a Regular-Expression offers comes some extra-amount of complexity. The routines in class StrCmpr and class StrIndexOf can eliminate for-loops and all the debugging that comes along with them - saving programmers countless hours of when their programs need only simple comparisons and searches that can be written without a RegEx.

    The methods in this class use substring comparison-logic, rather than token compares - meaning that the loops are checking only the characters within input parameter(s) comparStr. The characters before and after a match are ignored.

    Example:
    boolean result = StrCmpr.containsXOR_CI("Visited in August of this year." "july", "august");
    // Evaluates to TRUE
    
    boolean result = StrCmpr.containsXOR_CI("Traveled to Beijing last year.", "july", "august");
    // Evaluates to FALSE
    

    Methods Available

    Method-Name Key-Word Explanation
    NAND May not find any matches between the primary String srcStr parameter, and the String's passed to 'compareStr'

    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 'compareStr'.

    There is one 'philosophical note' which is that if multiple copies of an identical-String are passed via the comparison-Stringarray (String... comparestr), all XOR methods shall not pay heed to the notion that they the 'srcStr' parmeter 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 'compareStr' parameter.
    AND Must identify a containing-match between each and every String in String... compareStr and the primary 'srcStr' parameter.
    Starts With The provided compare-String (or String's) must match the beginning of parameter 'srcStr'.
    Ends With The provided compare-String (or String's) must match the ending of parameter 'srcStr'.
    Contains The provided compare-String (or String's) must be a substring of parameter 'srcStr'.
    CI (Case Insensitive) All equality-tests will be done on a Case Insensitive basis.


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 compareStr)
         { DEBUG_LOG.accept(methodName + "-MATCH[" + srcStr + ", " + compareStr + "] "); }
        

        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.

        public static boolean DEBUG = false;
        
      • 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 srcStr equals exactly one of the String's inside the 'compareStr' array.

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

        An internal counter is maintained, and it must equal precisely one prior to exit in order for TRUE to be returned. In the case that multiple copies of an identical String have been passed into parameter String[] compareStr, the returned-answer is best considered non-deterministic.. In practice, a second copy of an identical-String (or identical-ignoring case) will force the XOR comparison to return FALSE

        NOTE: No exception checks are performed on compareStr for duplicate elements in that array. This check is avoied essentially due to the performance over-head of checking for it.

        This performs the exact same comparison as Java's String.startsWith(String) method. Java provides an 'equalsIgnoreCase()' method, but not an 'startsWithIgnoreCase()'. This method does just that.
        Parameters:
        srcStr - This String is checked to see if it starts with the compareStr.
        compareStr - This String is checked against the srcStr - specifically, if srcStr ends with compareStr
        Returns:
        TRUE if srcStr starts with compareStr (ignoring-case), and FALSE otherwise.
        Code:
        Exact Method Body:
         return srcStr.regionMatches(true, 0, compareStr, 0, compareStr.length());

        This performs the exact same comparison as Java's String.endsWith(String) method. Java provides an 'equalsIgnoreCase()' method, but not an 'endsWithIgnoreCase()'. This method does just that.
        Parameters:
        srcStr - This String is checked to see if it ends with the compareStr.
        compareStr - This String is checked against the srcStr - specifically, if srcStr ends with compareStr
        Returns:

        Checks to ensure the substring of srcStr - demarcated by the parameters 'sPos' (inclusive) and 'ePos' (exclusive) - equals exactly one of the String's inside the 'compareStr' array.

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of a 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()
        compareStr - The String's used in the comparison against 'srcStr'
        Returns:
        This will return TRUE if and only if the specified substring between 'sPos' and 'ePos' (extraced from 'srcStr') equals exactly one of the 'compareStr' values.

        An internal counter is maintained, and it must equal precisely one prior to exit in order for TRUE to be returned. In the case that multiple copies of an identical String have been passed into parameter String[] compareStr, the returned-answer is best considered non-deterministic.. In practice, a second copy of an identical-String (or identical-ignoring case) will force the XOR comparison to return FALSE

        NOTE: No exception checks are performed on compareStr for duplicate elements in that array. This check is avoied essentially due to the performance over-head of checking for it.
        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 the substring of srcStr - demarcated by the parameters 'sPos' (inclusive) and 'ePos' (exclusive) - does not contain any of the String's inside the 'compareStr' array.

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of a 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()
        compareStr - The String's used in the comparison against 'srcStr'
        Returns:
        This will return TRUE if and only if the specified substring between 'sPos' and 'ePos' (extraced from 'srcStr') does not contain any of the 'compareStr' values.
        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 the substring of srcStr - demarcated by the parameters 'sPos' (inclusive) and 'ePos' (exclusive) - contains exactly one of the String's inside the 'compareStr' array.

        The test performed here ** is not ** case-sensitive.
        Parameters:

In the case that multiple copies of an identical String have been passed into parameter String[] compareStr, the returned-answer is best considered non-deterministic.. In practice, a second copy of an identical-String (or identical-ignoring case) will force the XOR comparison to return FALSE

        NOTE: No exception checks are performed on compareStr for duplicate elements in that array. This check is avoied essentially due to the performance over-head of checking for it.

        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

        Checks to ensure the substring of srcStr - demarcated by the parameters 'sPos' (inclusive) and 'ePos' (exclusive) - ends with exactly one of the String's inside the 'compareStr' array.

        The test performed here ** is not ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of a 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()
        compareStr - The String's used in the comparison against 'srcStr'
        Returns:
        This will return TRUE if and only if the specified substring between 'sPos' and 'ePos' (extraced from 'srcStr') ends with exactly one of the 'compareStr' values.

        An internal counter is maintained, and it must equal precisely one prior to exit in order for TRUE to be returned. In the case that multiple copies of an identical String have been passed into parameter String[] compareStr, the returned-answer is best considered non-deterministic.. In practice, a second copy of an identical-String (or identical-ignoring case) will force the XOR comparison to return FALSE

        NOTE: No exception checks are performed on compareStr for duplicate elements in that array. This check is avoied essentially due to the performance over-head of checking for it.
        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.

        The test performed here ** is ** case-sensitive.
        Parameters:
        srcStr - Any non-null instance of a java.lang.String
        compareStr - The String used in the comparison against 'srcStr'
        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:
        This will return TRUE if and only if the specified substring between 'sPos' and 'ePos' (extraced from 'srcStr') ends with 'compareStr'
        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
        cmpStrs - This is one (or many) java String's, each of which shall be compared to the ending of 'srcStr'.

      • CONTAINS

        🡅    
        protected static boolean CONTAINS​(boolean ignoresCase,
                                          byte booleanOperation,
                                          java.lang.String srcStr,
                                          java.lang.String[] cmpStrs)
        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
        cmpStrs - This is one (or many) java String's, each of which shall be compared to the ending of 'srcStr'.
        Returns:
        The appropriate response based on the inputs for boolean logic.
