- 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 DoublePredicate
Represents a predicate (boolean-valued function) of onedouble
-valued argument. This is thedouble
-consuming primitive type specialization ofPredicate
.This is a functional interface whose functional method is
test(double)

Method Detail
test
boolean test(double value)
Evaluates this predicate on the given argument.- Parameters:
value
- the input argument- Returns:
true
if the input argument matches the predicate, otherwisefalse
and
default DoublePredicate and(DoublePredicate 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 isfalse
, then theother
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 DoublePredicate 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 DoublePredicate or(DoublePredicate 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 istrue
, then theother
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
