LongPredicate | API reference | Android Developers

@FunctionalInterface 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).

Summary

Public methods
open LongPredicate!	`and(other: LongPredicate!)` Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
open LongPredicate!	`negate()` Returns a predicate that represents the logical negation of this predicate.
open LongPredicate!	`or(other: LongPredicate!)` Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
abstract Boolean	`test(value: Long)` Evaluates this predicate on the given argument.

Public methods

and

open fun and(other: LongPredicate!): LongPredicate!

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`	LongPredicate!: a predicate that will be logically-ANDed with this predicate

Return
`LongPredicate!`	a composed predicate that represents the short-circuiting logical AND of this predicate and the `other` predicate

Exceptions
`java.lang.NullPointerException`	if other is null

negate

open fun negate(): LongPredicate!

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

Return
`LongPredicate!`	a predicate that represents the logical negation of this predicate

or

open fun or(other: LongPredicate!): LongPredicate!

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`	LongPredicate!: a predicate that will be logically-ORed with this predicate

Return
`LongPredicate!`	a composed predicate that represents the short-circuiting logical OR of this predicate and the `other` predicate

Exceptions
`java.lang.NullPointerException`	if other is null

test

abstract fun test(value: Long): Boolean

Evaluates this predicate on the given argument.

Parameters
`value`	Long: the input argument

Return
`Boolean`	`true` if the input argument matches the predicate, otherwise `false`
