- 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)
.

Returns a composedDoubleConsumer
that performs, in sequence, this operation followed by theafter
operation.

Method Details
-
accept
void accept(double value)Performs this operation on the given argument.- Parameters:
value
- the input argument
-
andThen
Returns a composedDoubleConsumer
that performs, in sequence, this operation followed by theafter
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, theafter
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
