  • Method Details

    • getIntSet

      public IntSet getIntSet()

      getIntSet in interface CharacterClass

    • test

      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 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)
      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
