Class InverseCharacterClass

  • All Implemented Interfaces:
    java.util.function.IntPredicate, CharacterClass

    public class InverseCharacterClass
    extends java.lang.Object
    implements CharacterClass
    A character class represents a set of characters for regex matching purposes. An inverse character class is the complement of another character class

      Constructor Description
      InverseCharacterClass​(CharacterClass complement)
      Create the complement of a character class, that is, a character class containing exactly those characters that are not included in the supplied character class

      • InverseCharacterClass

        public InverseCharacterClass​(CharacterClass complement)
        Create the complement of a character class, that is, a character class containing exactly those characters that are not included in the supplied character class
        Parameters:

      • getComplement

        public CharacterClass getComplement()
        Get the character class of which this class is the complement
        Returns:
        the complement of this character class
      • test

        public boolean test​(int value)
        Specified by:
        test in interface java.util.function.IntPredicate
      • 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:
