Interface DistributedPredicate<T>

Type Parameters:

T - the type of the input to the predicate

All Superinterfaces:

java.util.function.Predicate<T>, Serializable

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 DistributedPredicate<T>
extends java.util.function.Predicate<T>, Serializable

Represents a predicate (boolean-valued function) of one argument.

This is a functional interface whose functional method is Predicate.test(Object).

Method Summary

Modifier and Type	Method and Description
default DistributedPredicate<T>	and(DistributedPredicate<? super T> other) Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
static <T> DistributedPredicate<T>	isEqual(Object targetRef) Returns a predicate that tests if two arguments are equal according to Objects.equals(Object, Object).
default DistributedPredicate<T>	negate() Returns a predicate that represents the logical negation of this predicate.
default DistributedPredicate<T>	or(DistributedPredicate<? super T> other) Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.

Method Detail

isEqual

static <T> DistributedPredicate<T> isEqual(Object targetRef)

Returns a predicate that tests if two arguments are equal according to Objects.equals(Object, Object).

Specified by:

isEqual in interface java.util.function.Predicate<T>

Type Parameters:

T - the type of arguments to the predicate

Parameters:

targetRef - the object reference with which to compare for equality, which may be null

Returns:

a predicate that tests if two arguments are equal according to Objects.equals(Object, Object)

and

default DistributedPredicate<T> and(DistributedPredicate<? 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 - 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 DistributedPredicate<T> negate()

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

Specified by:

negate in interface java.util.function.Predicate<T>

Returns:

a predicate that represents the logical negation of this predicate

or

default DistributedPredicate<T> or(DistributedPredicate<? 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 - 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
