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.
@FunctionalInterfacepublic interfaceLongConsumer
Represents an operation that accepts a singlelong-valued argument and returns no result. This is the primitive type specialization ofConsumer forlong. Unlike most other functional interfaces,LongConsumer is expected to operate via side-effects.

This is afunctional interface whose functional method isaccept(long).

    Description
    void
    accept(long value)
    Performs this operation on the given argument.
    Returns a composedLongConsumer that performs, in sequence, this operation followed by theafter operation.

  • Method Details

    • 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 composedLongConsumer that performs, in sequence, this operation followed by theafter 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, theafter operation will not be performed.
      Parameters:
      after - the operation to perform after this operation
      Returns:
      a composedLongConsumer that performs in sequence this operation followed by theafter operation
      Throws:
      NullPointerException - ifafter is null
