Type Parameters
<T>
the type of the first argument to the predicate
<U>
the type of the second argument the predicate
Imports
java.util.Objects

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).

public default BiPredicate<T, U>

Returns:

a predicate that represents the logical negation of this predicate
negate
()

Method Detail

andback to summary
public 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:BiPredicate<? super T, ? super U>

a predicate that will be logically-ANDed with this predicate

Returns:BiPredicate<T, U>

a composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate

Exceptions
NullPointerException:
if other is null
negateback to summary
public default BiPredicate<T, U> negate()

Returns a predicate that represents the logical negation of this predicate.

Returns:BiPredicate<T, U>

a predicate that represents the logical negation of this predicate

orback to summary
public 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:BiPredicate<? super T, ? super U>

a predicate that will be logically-ORed with this predicate

Returns:BiPredicate<T, U>

a composed predicate that represents the short-circuiting logical OR of this predicate and the other predicate

Exceptions
NullPointerException:
if other is null
testback to summary
public boolean test(T t, U u)

Evaluates this predicate on the given arguments.

Parameters
t:T

the first input argument

u:U

the second input argument

Returns:boolean

true if the input arguments match the predicate, otherwise false
