Method Detail

test

public boolean test(int value)

Specified by:

test in interface 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
