- 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 DoubleConsumer
Represents an operation that accepts a singledouble-valued argument and returns no result. This is the primitive type specialization ofConsumerfordouble. Unlike most other functional interfaces,DoubleConsumeris expected to operate via side-effects.This is a functional interface whose functional method is
accept(double).- Since:

Method Detail
accept
void accept(double value)
Performs this operation on the given argument.- Parameters:
-
value- the input argument
andThen
default DoubleConsumer andThen(DoubleConsumer after)
Returns a composedDoubleConsumerthat performs, in sequence, this operation followed by theafteroperation. If performing either operation throws an exception, it is relayed to the caller of the composed operation. If performing this operation throws an exception, theafteroperation will not be performed.- Parameters:
-
after- the operation to perform after this operation - Returns:
-
a composed
DoubleConsumerthat performs in sequence this operation followed by theafteroperation - Throws:
-
NullPointerException- ifafteris null
