Package net.sf.saxon.regex.charclass

## Class Categories.Category

- java.lang.Object
- - net.sf.saxon.regex.charclass.Categories.Category

- All Implemented Interfaces:
    `java.util.function.IntPredicate`, `CharacterClass`
  Enclosing class:
    Categories

      public static class Categories.Category
      extends java.lang.Object
      implements CharacterClass

  A Category is a CharacterClass represented in a regular expression as \p{Xx}. The label Xx is retained, and can be used to determine whether or not two categories are disjoint.

    - #### Category

          public Category​(java.lang.String label,
                          java.util.function.IntPredicate predicate)

  - ### Method Detail

    - #### 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:
        `getIntSet` in interface `CharacterClass`
