- 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 single double
-valued argument and returns no result. This is the primitive type specialization of Consumer
for double
. Unlike most other functional interfaces, DoubleConsumer
is expected to operate via side-effects.
This is a functional interface whose functional method is accept(double)
.

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 composed DoubleConsumer
that performs, in sequence, this operation followed by the after
operation. If performing either operation throws an exception, it is relayed to the caller of the composed operation. If performing this operation throws an exception, the after
operation will not be performed.
- Parameters:
-
after
- the operation to perform after this operation - Returns:
- a composed
DoubleConsumer
that performs in sequence this operation followed by theafter
operation - Throws:
-
NullPointerException
- ifafter
is null
