IntPredicate
public interface IntPredicate
| java.util.function.IntPredicate |
Represents a predicate (boolean-valued function) of one int-valued argument. This is the int-consuming primitive type specialization of Predicate.
This is a functional interface whose functional method is test(int).

|---|---|
default IntPredicate | and(IntPredicate other) Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another. |
default IntPredicate | negate() Returns a predicate that represents the logical negation of this predicate. |
default IntPredicate | or(IntPredicate other) Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another. |
abstract boolean | test(int value) Evaluates this predicate on the given argument. |
Public methods
and
public IntPredicate and (IntPredicate 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 | IntPredicate: a predicate that will be logically-ANDed with this predicate |
| Returns | |
|---|---|
IntPredicate | a composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate |
| Throws | |
|---|---|
NullPointerException | if other is null |
negate
public IntPredicate negate ()
Returns a predicate that represents the logical negation of this predicate.
| Returns | |
|---|---|
IntPredicate | a predicate that represents the logical negation of this predicate |
or
public IntPredicate or (IntPredicate 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 | IntPredicate: a predicate that will be logically-ORed with this predicate |
| Returns | |
|---|---|
IntPredicate | a composed predicate that represents the short-circuiting logical OR of this predicate and the other predicate |
| Throws | |
|---|---|
NullPointerException | if other is null |
test
public abstract boolean test (int value)
Evaluates this predicate on the given argument.
| Parameters | |
|---|---|
value | int: the input argument |
| Returns | |
|---|---|
boolean | true if the input argument matches the predicate, otherwise false |
