Class PredicateCharacterClass

  • All Implemented Interfaces:
    java.util.function.IntPredicate, CharacterClass, IntPredicateProxy
    public class PredicateCharacterClass
extends java.lang.Object
implements CharacterClass
    A character class represents a set of characters for regex matching purposes. A predicate character class is one where the determination of membership is established by executing a function.

        public boolean test​(int value)
        Description copied from interface: CharacterClass
        Test whether a particular codepoint is a member of the character class
        Specified by:
        test in interface CharacterClass
        Specified by:
        test in interface java.util.function.IntPredicate
        Specified by:
        test in interface IntPredicateProxy
        Parameters:
        value - the codepoint to be tested
        Returns:
        true if it matches

      • isDisjoint

        public boolean isDisjoint​(CharacterClass other)
        Description copied from interface: CharacterClass
        Ask whether this character class is known to be disjoint with another character class (that is, the two classes have no characters in common). If in doubt, return false.
        Specified by:
        isDisjoint in interface CharacterClass
        Parameters:
        other - the other character class
        Returns:
        true if the character classes are known to be disjoint; false if there may be characters in common between the two classes

      • getIntSet

        public IntSet getIntSet()
        Description copied from interface: CharacterClass
        Get the set of matching characters if available. If not available, return null
        Specified by:
        getIntSet in interface CharacterClass
