Interface LongConsumer

- 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)
.

Method Detail
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 theafter
operation - Throws:
-
NullPointerException
- ifafter
is null
