DoubleConsumer
public
interface
DoubleConsumer
| java.util.function.DoubleConsumer
|
Known indirect subclasses
|
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).
Summary
Public methods |
|---|
abstract
void
|
accept(double value)
Performs this operation on the given argument.

DoubleConsumer
|
andThen(DoubleConsumer after)
Returns a composed DoubleConsumer that performs, in sequence, this
operation followed by the after operation.

Public methods
accept
public abstract void accept (double value)
Performs this operation on the given argument.
| Parameters |
|---|
value |
double: the input argument |
andThen
public 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 |
DoubleConsumer: the operation to perform after this operation |
| Returns |
|---|
DoubleConsumer |
a composed DoubleConsumer that performs in sequence this
operation followed by the after operation |
