- Type Parameters:
T- the type of the first argument to the predicateU- 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.
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).

Method Summary
Modifier and TypeMethodDescriptiondefault 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.booleanEvaluates this predicate on the given arguments.

Method Details
-
test
Evaluates this predicate on the given arguments.- Parameters:
t- the first input argumentu- the second input argument- Returns:
trueif the input arguments match the predicate, otherwisefalse
-
and
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
Returns a predicate that represents the logical negation of this predicate.- Returns:
- a predicate that represents the logical negation of this predicate
-
or
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
