Class Delimiter

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.CharSequence, java.lang.Comparable<java.lang.CharSequence>
    public class Delimiter
extends CSSToken
implements java.lang.CharSequence, java.io.Serializable, java.lang.Comparable<java.lang.CharSequence>
    This is a Token Data-Class. It is a descendant of the root CSSToken-Class: CSSToken. Instances of the class are usually are produced by the CSSTokenizer class. Many (but not all) of these subclasses maintain a static-method for building instances of this class named 'build'. Any CSSToken-subclass that is neither a singleton-instance, nor an "Error-Subtype" should have such a builder. Singeton instances do not need builders, and the two Error-Subtype Classes can only be generated by the tokenizer.

    All CSSToken subclasses have a CSSToken.str field which contains the exact character data that was extracted and used to construct instances of this class. All sub-casses also have several "Loop Optimization" methods. These are methods that may or may not be useful in light of some of the newer additions to JDK 17 & 21 including the 'instanceof varName' conditional-expression variable-naming features.

    The algorithms used to write this tokenizer were generated based solely on the CSS Working-Group's Syntax-Documentation. This document may be viewed here: CSS Working-Group CSS-Syntax. There is an external site that maintain all thing CSS located at drafts.csswg.org

        protected static final long serialVersionUID
        This fulfils the SerialVersion UID requirement for all classes that implement Java's interface java.io.Serializable. Using the Serializable Implementation offered by java is very easy, and can make saving program state when debugging a lot easier. It can also be used in place of more complicated systems like "hibernate" to store data as well.

      • isDelimiter

        🡅  🡇  ⇈  ⮫ 🗕  🗗  🗖 
        public final boolean isDelimiter()
        Description copied from class: CSSToken
        Loop Optimization: This method only returns TRUE if this is an actual instance of Delimiter.
        Overrides:
        isDelimiter in class CSSToken
        Returns:
        This method returns FALSE for all instances of CSSToken, except when 'this' instance is actually the Delimiter Subclass.

        That class has overridden this method, and returns TRUE.

      • ifDelimiter

        🡅  ⇈  ⮫ 🗕  🗗  🗖 
        public final Delimiter ifDelimiter()
        Description copied from class: CSSToken
        Loop Optimization: When this method is invoked on an instance of sub-class Delimiter this method produces 'this' instance.
        Overrides:
        ifDelimiter in class CSSToken
        Returns:
        This method shall return null, always, except when 'this' is an actual instance of Delimiter. When so, this method simply returns 'this'. All other sub-classes of (abstract) class CSSToken inherit this method, and therefore return null.
