@FunctionalInterface

Imports

java.util.Objects

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).

Since: 1.8
See Also: Consumer

public 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.

public 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:DoubleConsumer: the operation to perform after this operation

Returns:DoubleConsumer

a composed DoubleConsumer that performs in sequence this operation followed by the after operation

Exceptions

NullPointerException:: if after is null
