Interface LongPredicate

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 LongPredicate

Represents a predicate (boolean-valued function) of one long-valued argument. This is the long-consuming primitive type specialization of Predicate.

This is a functional interface whose functional method is test(long).

Since:: 1.8

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default LongPredicate`	`and(LongPredicate other)`	Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
`default LongPredicate`	`negate()`	Returns a predicate that represents the logical negation of this predicate.
`default LongPredicate`	`or(LongPredicate other)`	Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
`boolean`	`test(long value)`	Evaluates this predicate on the given argument.

Method Detail

test

boolean test(long 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 LongPredicate and(LongPredicate 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 LongPredicate 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 LongPredicate or(LongPredicate 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
