T
- the type of the input to the predicate@FunctionalInterface public interface Predicate<T>
This is a functional interface
whose functional method is test(Object)
.
Modifier and Type | Method | Description |
---|---|---|
default Predicate<T> |
and (Predicate<? super T> other) |
Returns a composed predicate that represents a short-circuiting logical
AND of this predicate and another.
|
static <T> Predicate<T> |
isEqual (Object targetRef) |
Returns a predicate that tests if two arguments are equal according
to
Objects.equals(Object, Object) . |
default Predicate<T> |
negate () |
Returns a predicate that represents the logical negation of this
predicate.
|
default Predicate<T> |
or (Predicate<? super T> other) |
Returns a composed predicate that represents a short-circuiting logical
OR of this predicate and another.
|
boolean |
test (T t) |
Evaluates this predicate on the given argument.

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.
