## 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

- - ### Method Summary

    All Methods Instance Methods Abstract Methods Default 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.

- - ### 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 the `after` operation
      Throws:
        `NullPointerException` - if `after` is null
