Predicate
| java.util.function.Predicate<T> |
Represents a predicate (boolean-valued function) of one argument.
This is a functional interface
whose functional method is test(Object).
Public methods | |
|---|---|
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 |
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. |
abstract
boolean
|
test(T t)
Evaluates this predicate on the given argument. |
Predicate<T> and (Predicate<? super T> 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 |
Predicate:
a predicate that will be logically-ANDed with this
predicate |
| Returns | |
|---|---|
Predicate<T> |
a composed predicate that represents the short-circuiting logical
AND of this predicate and the other predicate |
| Throws | |
|---|---|
NullPointerException |
if other is null |
Predicate<T> isEqual (Object targetRef)
Returns a predicate that tests if two arguments are equal according
to equals(Object, Object).
| Parameters | |
|---|---|
targetRef |
Object:
the object reference with which to compare for equality,
which may be null |
| Returns | |
|---|---|
Predicate<T> |
a predicate that tests if two arguments are equal according
to equals(Object, Object)
|
Predicate<T> negate ()
Returns a predicate that represents the logical negation of this predicate.
| Returns | |
|---|---|
Predicate<T> |
a predicate that represents the logical negation of this predicate |
Predicate<T> or (Predicate<? super T> 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 |
Predicate:
a predicate that will be logically-ORed with this
predicate |
| Returns | |
|---|---|
Predicate<T> |
a composed predicate that represents the short-circuiting logical
OR of this predicate and the other predicate |
| Throws | |
|---|---|
NullPointerException |
if other is null |
boolean test (T t)
Evaluates this predicate on the given argument.
| Parameters | |
|---|---|
t |
T:
the input argument |
| Returns | |
|---|---|
boolean |
true if the input argument matches the predicate,
otherwise false
