java8.util.function.DoublePredicates

public final class DoublePredicates
extends java.lang.Object

A place for static default implementations of the new Java 8 default interface methods and static interface methods in the DoublePredicate interface.

Method Summary

Modifier and Type	Method and Description
static DoublePredicate	and(DoublePredicate this_, DoublePredicate other) Returns a composed predicate that represents a short-circuiting logical AND of the this_ predicate and another.
static DoublePredicate	negate(DoublePredicate this_) Returns a predicate that represents the logical negation of the this_ predicate.
static DoublePredicate	or(DoublePredicate this_, DoublePredicate other) Returns a composed predicate that represents a short-circuiting logical OR of the this_ predicate and another.

Method Detail

and

public static DoublePredicate and(DoublePredicate this_,
                                  DoublePredicate other)

Returns a composed predicate that represents a short-circuiting logical AND of the this_ predicate and another. When evaluating the composed predicate, if the 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 the this_ predicate throws an exception, the other predicate will not be evaluated.

Parameters:

this_ - a predicate that will be logically-ANDed with the other predicate

other - a predicate that will be logically-ANDed with the this_ predicate

Returns:

a composed predicate that represents the short-circuiting logical AND of the this_ predicate and the other predicate

Throws:

java.lang.NullPointerException - if this_ is null

java.lang.NullPointerException - if other is null

negate

public static DoublePredicate negate(DoublePredicate this_)

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

Parameters:

this_ - the predicate that will be negated

Returns:

a predicate that represents the logical negation of the this_ predicate

Throws:

java.lang.NullPointerException - if this_ is null

or

public static DoublePredicate or(DoublePredicate this_,
                                 DoublePredicate other)

Returns a composed predicate that represents a short-circuiting logical OR of the this_ predicate and another. When evaluating the composed predicate, if the 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 the this_ predicate throws an exception, the other predicate will not be evaluated.

Parameters:

this_ - a predicate that will be logically-ORed with the other predicate

other - a predicate that will be logically-ORed with the this_ predicate

Returns:

a composed predicate that represents the short-circuiting logical OR of the this_ predicate and the other predicate

Throws:

java.lang.NullPointerException - if this_ is null

java.lang.NullPointerException - if other is null
