Interface LongConsumer

All Known Subinterfaces:
LongStream.Builder
All Known Implementing Classes:
LongSummaryStatistics
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 LongConsumer

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

Methods

Modifier and Type Method and Description
void accept(long value)

Performs this operation on the given argument.
default LongConsumer andThen(LongConsumer after)

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

Methods

accept

void accept(long value)

Performs this operation on the given argument.

Parameters:
value - the input argument

andThen

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 - the operation to perform after this operation
Returns:
a composed LongConsumer that performs in sequence this operation followed by the after operation
Throws:
NullPointerException - if after is null
