DoublePredicate
public
interface
DoublePredicate
| java.util.function.DoublePredicate
|
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).

Public methods
and
public 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 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 |
DoublePredicate: a predicate that will be logically-ANDed with this
predicate |
| Returns |
|---|
DoublePredicate |
a composed predicate that represents the short-circuiting logical
AND of this predicate and the other predicate |
negate
public DoublePredicate negate ()
Returns a predicate that represents the logical negation of this
predicate.
| Returns |
|---|
DoublePredicate |
a predicate that represents the logical negation of this
predicate |
or
public 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 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 |
DoublePredicate: a predicate that will be logically-ORed with this
predicate |
| Returns |
|---|
DoublePredicate |
a composed predicate that represents the short-circuiting logical
OR of this predicate and the other predicate |
test
public abstract boolean test (double value)
Evaluates this predicate on the given argument.
| Parameters |
|---|
value |
double: the input argument |
| Returns |
|---|
boolean |
true if the input argument matches the predicate,
otherwise false |
