public interface BiPredicate

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 Method Summary

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.
BiPredicate<T, U>
negate()
Returns a predicate that represents the logical negation of this predicate.
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 Methods

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 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

public 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

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 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

public abstract 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, otherwise false
