java.util.function

Interface BiPredicate<T,U>

Type Parameters:

T - the type of the first argument to test.

U - the type of the second argument to test.

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 BiPredicate<T,U>

Determines if the input objects match some criteria. This is the two-arity specialization of Predicate.

Since:

Method Summary

Modifier and Type	Method and Description
default BiPredicate<T,U>	and(BiPredicate<? super T,? super U> p) Returns a predicate which evaluates to true only if this predicate and the provided predicate both evaluate to true.
default BiPredicate<T,U>	negate() Returns a predicate which negates the result of this predicate.
default BiPredicate<T,U>	or(BiPredicate<? super T,? super U> p) Returns a predicate which evaluates to true if either this predicate or the provided predicate evaluates to true.
boolean	test(T t, U u) Return true if the inputs match some criteria.
default BiPredicate<T,U>	xor(BiPredicate<? super T,? super U> p) Returns a predicate that evaluates to true if both or neither of the component predicates evaluate to true.

Method Detail

test

boolean test(T t,
             U u)

Return true if the inputs match some criteria.

Parameters:

t - an input object.

u - an input object.

Returns:

true if the inputs match some criteria.

and

default BiPredicate<T,U> and(BiPredicate<? super T,? super U> p)

Returns a predicate which evaluates to true only if this predicate and the provided predicate both evaluate to true. If this predicate returns false then the remaining predicate is not evaluated.

Parameters:

p - a predicate which will be logically-ANDed with this predicate.

Returns:

a new predicate which returns true only if both predicates return true.

negate

default BiPredicate<T,U> negate()

Returns a predicate which negates the result of this predicate.

Returns:

a new predicate who's result is always the opposite of this predicate.

or

default BiPredicate<T,U> or(BiPredicate<? super T,? super U> p)

Returns a predicate which evaluates to true if either this predicate or the provided predicate evaluates to true. If this predicate returns true then the remaining predicate is not evaluated.

Parameters:

p - a predicate which will be logically-ORed with this predicate.

Returns:

a new predicate which returns true if either predicate returns true.

xor

default BiPredicate<T,U> xor(BiPredicate<? super T,? super U> p)

Returns a predicate that evaluates to true if both or neither of the component predicates evaluate to true.

Parameters:

p - a predicate which will be logically-XORed with this predicate.

Returns:

a predicate that evaluates to true if both or neither of the component predicates evaluate to true.
