Annotations

@FunctionalInterface

Imports

java.util.Objects

Represents an operation that accepts a single long-valued argument and returns no result. This is the primitive type specialization of Consumer for long. Unlike most other functional interfaces, LongConsumer is expected to operate via side-effects.

This is a functional interface whose functional method is accept(long).

Since: 1.8
See Also: Consumer

public default LongConsumer andThen(LongConsumer after) Returns a composed `LongConsumer` 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 LongConsumer andThen(LongConsumer after)

Returns a composed LongConsumer 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:LongConsumer: the operation to perform after this operation

Returns:LongConsumer

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

Exceptions

NullPointerException:: if after is null
