- 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 singlelong-valued argument and returns no result. This is the primitive type specialization ofConsumerforlong. Unlike most other functional interfaces,LongConsumeris expected to operate via side-effects.This is a functional interface whose functional method is
accept(long).- Since:

void accept(long value)
Performs this operation on the given argument.- Parameters:
-
value- the input argument
andThen
default LongConsumer andThen(LongConsumer after)
Returns a composedLongConsumerthat performs, in sequence, this operation followed by theafteroperation. If performing either operation throws an exception, it is relayed to the caller of the composed operation. If performing this operation throws an exception, theafteroperation will not be performed.- Parameters:
-
after- the operation to perform after this operation - Returns:
-
a composed
