- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
Represents a predicate (boolean-valued function) of one
double-valued
argument. This is the double-consuming primitive type specialization
of Predicate.
This is a functional interface
whose functional method is test(double).

Method Details
-
test
boolean test(double value) Evaluates this predicate on the given argument.- Parameters:
value- the input argument- Returns:
trueif the input argument matches the predicate, otherwisefalse
-
and
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 theotherpredicate 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
otherpredicate 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
otherpredicate - Throws:
NullPointerException- if other is null
-
negate
Returns a predicate that represents the logical negation of this predicate.- Returns:
- a predicate that represents the logical negation of this predicate
-
or
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 theotherpredicate 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
otherpredicate 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
otherpredicate - Throws:
NullPointerException- if other is null
