Class InnerTagRemove

  • public class InnerTagRemove
extends java.lang.Object
    InnerTagRemove 🠞
    1. InnerTag: This implies that Attribute key-value pairs located within the HTML TagNode instances themselves are used as a search criteria for retrieving TagNode's.

    2. Remove: This implies that node matches are removed from the underlying input-Vector. This method will return a total count of the number of nodes removed.
    Removes tags from Vectorized-HTML by matching them using a search-criteria that is specified by the names & values of a tag's attributes (Inner-Tags).

    Methods Available

    Method Explanation
    first (...) This will remove the first TagNode match found inside the vectorized-page parameter 'html'.
    nth (...) This will remove the nth TagNode match found inside the vectorized-page parameter 'html'.
    last (...) This will remove the last TagNode match found inside the vectorized-page parameter 'html'.
    nthFromEnd (...) This will remove the nth-from-last TagNode match found inside the vectorized-page parameter 'html'.
    all (...) This will remove every TagNode match found inside the vectorized-page parameter 'html'.

    Method Parameters

    Parameter Explanation
    Vector<? extends HTMLNode> html This represents any vectorized HTML page, sub-page, or list of partial-elements.
    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 HTMLNode's that are found between the specified Vector indices will be considered for matching with the search criteria.

    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 vectorized-html page that was passed. (html.size() of parameter Vector<HTMLNode> html).

    EXCEPTIONS: An IndexOutOfBoundsException will be thrown if:

    • If sPos is negative, or if sPos is greater-than or equal-to the size of the input Vector
    • If ePos is zero, or greater than the size of the input Vector.
    • If sPos is a larger integer than ePos
    String htmlTag When this parameter is present, only HTMLNode's which are both instances of class TagNode *and* have a TagNode.tok field whose value is equal to this parameter 'htmlTag', will be returned as matches.

    COMMON EXAMPLES: Some common examples of valid 'htmlTags' are: a, div, img, table, tr, meta as well as all other valid HTML element-tokens.

    NOTE: This comparison is performed using a case-insensitive compare-method.

    EXCEPTIONS: If this parameter is not a valid HTML element, an HTMLTokException will be thrown.
    String... htmlTags When this parameter is present, only HTMLNode's which are both instances of class TagNode *and* whose TagNode.tok field String-value matches (is equal to) at least one of the elements in this VarArgs String parameter-set will be considered for a match. The same example HTML elements used in the previous parameter description apply here as well (a, div, img, table, tr, meta) etc...

    NOTE: This comparison is performed using a case-insensitive compare-method.

    EXCEPTIONS: If even one of the elements in this parameter-set is an invalid HTML token, an HTMLTokException will be thrown.

    FINALLY: This parameter is only available as an option for search-methods that utilize the Predicate<TagNode> parameter-option too. Most of the search-method options available in this class allow only one HTML 'token' element as a search parameter option.
    String innerTag This parameter is mandatory for every method here, except one's that receive a Predicate<TagNode> parameter. This parameter is used to identify the HTML-attribute or "Inner Tag" for whose values the programmer is comparing or testing.

    NOTE: The comparison's performed on the HTML element for the attribute name are performed using a case-insensitive compare-method.

    EXCEPTIONS: An InnerTagKeyException will be thrown if this parameter does not represent a valid HTML attribute name.

    USE: Whenever this parameter is present, the value retrieved from the invocation of tagNode.AV(innerTag) are always passed to the text-comparing methods listed below.

    MOST COMMON: The most common example String's used for parameter 'innerTag' (also called 'attribute') would include tags such as: 'id', 'class', 'src', 'href', 'style', 'width', 'onclick', 'onload', etc...
    TextComparitor tc WORKS WITH: This parameter works in coordination with parameter 'innerTag'. After the Attribute-value is retrieved from an HTML-element by method call: tagNode.AV(innerTag); The results from this invocation are sent to TextComparitor parameter 'tc'.

    ALSO WITH: This parameter also utilizes / works alongside the String... compareStr parameter for performing it's comparisons of the attribute list inside of a given HTML element TagNode.

    When this parameter is present in a method-signature parameter-list, the decision of whether a TagNode is to be included in the search result-set is defined by this parameter's BiPredicate.test(...) method. TextComparitor is a Java BiPredicate<String, String[]>, which compares the attribute-value that was retrieved with a list of compare-String's (parameter 'compareStr').
    Pattern p WORKS WITH: This parameter works in coordination with parameter 'innerTag'. After the Attribute-value is retrieved from HTML-element by method call: tagNode.AV(innerTag); The results from this call are sent to Regular-Expression Pattern 'p'.

    When this parameter is present in the method-signature parameter-list, the decision of whether a TagNode is to be included in the search result-set are made by the regular expression generated 'Matcher' against the attribute-value that was retrieved.

    Specifically: p.asPredicate().test(attribute_value)
    Predicate<String> p WORKS WITH: This parameter works in coordination with parameter 'innerTag'. After the Attribute-value is retrieved from an HTML-element by method call: tagNode.AV(innerTag); The results from this call are sent to this Java Functional Interface Predicate parameter 'p'.

    When this parameter is present in the method-signature parameter-list, the decision of whether a TagNode is to be included in the search result-set are made by the results of the Java Predicate.test(String) method.

    Specifically: p.test(attribute_value)
    String... compareStr WORKS WITH: This parameter works in coordination with parameter TextComparitor tc. This parameter supplies the String's with which the comparisons of the attribute-value may be compared.

    For Example: If the following values (below) were passed to these search-methods:

    1. If: 'innerTag' were equal to 'class'
    2. And: 'tc' were equal to TextComparitor.C
    3. And: 'compareStr' were equal to 'MyMainClass'

    The search would match any and all TagNode instances whose CSS 'class' contained 'MyMainClass'
    Predicate<TagNode> When this parameter is present in the method-signature parameter-list, the decision of whether a TagNode is to be included in the search result-set are made by calling this Predicate's test(TagNode) method.

    Return Values:

    1. int reveals exactly how many TagNode's were successfully removed from the html vectorized-page parameter 'html'



    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 fields. It is a concept very similar to the Java-Bean's @Stateless Annotation.
