Class InverseCharacterClass

java.lang.Object
net.sf.saxon.regex.charclass.InverseCharacterClass
All Implemented Interfaces:
IntPredicate, CharacterClass, IntPredicateProxy
public class InverseCharacterClass extends 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 Details

    • 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:
      complement - the class of which this one is the complement

  • Method Details

    • 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)
      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)
      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
