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 and 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

Method Summary

Modifier and Type	Method and Description
CharacterClass	getComplement() Get the character class of which this class is the complement
IntSet	getIntSet() Get the set of matching characters if available.
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).

Constructor Detail

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 Detail

getComplement

public CharacterClass getComplement()

Get the character class of which this class is the complement

Returns:

the complement of this character class

matches

public boolean matches(int value)

Description copied from interface: IntPredicate

Ask whether a given value matches this predicate

Specified by:

matches in interface IntPredicate

Parameters:

value - the value to be tested

Returns:

true if the value matches; false if it does not

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
