BiPredicate

public interface BiPredicate

java.util.function.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(java.lang.Object, java.lang.Object).

Summary

Public methods

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.

abstract boolean test(T t, U u)

Evaluates this predicate on the given arguments.

public 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: 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
Throws
NullPointerException if other is null

negate

Added in API level 24 
public 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

or

Added in API level 24 
public 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: 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
Throws
NullPointerException if other is null

test

Added in API level 24 
public abstract 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
