Interface IntPredicate

Functional Interface:: This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface 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).

Since:: 1.8

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`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.
`boolean`	`test(int value)`	Evaluates this predicate on the given argument.

Method Detail

test

boolean test(int value)

Evaluates this predicate on the given argument.

Parameters:: value - the input argument
Returns:: true if the input argument matches the predicate, otherwise false

and

default 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 - 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

negate

default IntPredicate negate()

Returns a predicate that represents the logical negation of this predicate.

Returns:: a predicate that represents the logical negation of this predicate

or

default 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 - 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
