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 of Predicate
.
This is a functional interface whose functional method is test(Object, Object)
.

Modifier and Type | Method | Description |
---|---|---|
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. |
default BiPredicate<T,U> | negate() | Returns a predicate that represents the logical negation of this predicate. |
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. |
boolean | test(T t,

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:
-
true
if 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 is false
, then the other
predicate 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 other
predicate 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
other
predicate - 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 is true
, then the other
predicate 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 other
predicate 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
other
predicate - Throws:
-
NullPointerException
- if other is null
