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).
Public Method Summary

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.

accept
(double value)
Performs this operation on the given argument.
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 the after operation
