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)
.

Summary
Public methods | |
---|---|
default DoublePredicate | and(DoublePredicate other) Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another. |
default DoublePredicate | negate() Returns a predicate that represents the logical negation of this predicate. |
default DoublePredicate | or(DoublePredicate other) Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another. |
abstract boolean | test(double value) Evaluates this predicate on the given argument. |
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 |
Throws | |
---|---|
NullPointerException | if other is null |
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 |
Throws | |
---|---|
NullPointerException | if other is null |
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 |
