Interface BiPredicate<T,U>
-
- Type Parameters:
-
T- the type of the first argument to the predicate -
U- the type of the second argument the predicate
- 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>
Represents a predicate (boolean-valued function) of two arguments. This is the two-arity specialization ofPredicate.This is a functional interface whose functional method is
test(Object, Object).- Since:

Method Detail
test
boolean test(T t, U u)
Evaluates this predicate on the given arguments.- Parameters:
-
t- the first input argument -
u- the second input argument - Returns:
-
trueif the input arguments match the predicate, otherwisefalse
and
default BiPredicate<T,U> and(BiPredicate<? super T,? super U> other)
Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another. When evaluating the composed predicate, if this predicate isfalse, then theotherpredicate is not evaluated.Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the
otherpredicate will not be evaluated.- Parameters:
-
other- a predicate that will be logically-ANDed with this predicate - Returns:
-
a composed predicate that represents the short-circuiting logical AND of this predicate and the
otherpredicate - Throws:
-
NullPointerException- if other is null
negate
default BiPredicate<T,U> negate()
Returns a predicate that represents the logical negation of this predicate.- Returns:
- a predicate that represents the logical negation of this predicate
or
default BiPredicate<T,U> or(BiPredicate<? super T,? super U> other)
Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another. When evaluating the composed predicate, if this predicate istrue, then theotherpredicate is not evaluated.Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the
otherpredicate will not be evaluated.- Parameters:
-
other- a predicate that will be logically-ORed with this predicate - Returns:
-
a composed predicate that represents the short-circuiting logical OR of this predicate and the
otherpredicate - Throws:
-
NullPointerException- if other is null
