Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface CharPredicate

A Type Specific Function interface that reduces boxing/unboxing and fills the gaps of interfaces that are missing.

Method Summary

Modifier and Type	Method and Description
static CharPredicate	alwaysFalse() Creates a Always false function that may be useful if you don't need to process information or just want a default.
static CharPredicate	alwaysTrue() Creates a Always true function that may be useful if you don't need to process information or just want a default.
default CharPredicate	andType(CharPredicate other) A Type specific and-function helper function that reduces boxing/unboxing
default CharPredicate	negate() A type specific inverter function
default CharPredicate	orType(CharPredicate other) A Type specific or-function helper function that reduces boxing/unboxing
boolean	test(char k) Type Specific get function to reduce boxing/unboxing

Method Detail

test

boolean test(char k)

Type Specific get function to reduce boxing/unboxing

Parameters:

k - the value that should be processed

Returns:

the result of the function

alwaysTrue

static CharPredicate alwaysTrue()

Creates a Always true function that may be useful if you don't need to process information or just want a default.

Returns:

a default returning function

alwaysFalse

static CharPredicate alwaysFalse()

Creates a Always false function that may be useful if you don't need to process information or just want a default.

Returns:

a default returning function

andType

default CharPredicate andType(CharPredicate other)

A Type specific and-function helper function that reduces boxing/unboxing

Parameters:

other - the other function that should be merged with.

Returns:

a function that compares values in a and comparason

negate

default CharPredicate negate()

A type specific inverter function

Returns:

the same function but inverts the result

orType

default CharPredicate orType(CharPredicate other)

A Type specific or-function helper function that reduces boxing/unboxing

Parameters:

other - the other function that should be merged with.

Returns:

a function that compares values in a or comparason
