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.

Returns a composed predicate that represents a short-circuiting logical
OR of this predicate and another.

test(T t, U u)
Evaluates this predicate on the given arguments.

Public methods
and
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 |
negate
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
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 |
test
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 |
