Method Detail

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

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 java.util.function.IntPredicate

Specified by:

test in interface CharacterClass

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
