      Specified by:
      andThen in interface LongConsumer

    • boxed

      default Consumer<Long> boxed()
      Returns a boxed version of this consumer.
      Returns:

    • when

      default LongConsumer when(LongPredicate predicate)
      Returns a consumer that conditionally invokes this consumer when allowed by the specified predicate.
      Parameters:
      predicate - a predicate that determines whether or not to invoke this consumer
      Returns:
      a consumer that conditionally invokes this consumer when allowed by the specified predicate.

    • withDefault

      default LongConsumer withDefault(LongPredicate predicate, LongSupplier defaultValue)
      Returns a consumer that accepts the value returned by the specified default provider if its value does not match the specified predicate.
      Parameters:
      predicate - a predicate used to determine the parameter of this consumer
      defaultValue - a provider of the default parameter value
      Returns:
      a consumer that accepts the value returned by the specified default provider if its value does not match the specified predicate.

    • composeAsLong

      default LongConsumer composeAsLong(LongUnaryOperator composer)
      Composes a consumer that invokes this consumer using result of the specified function.
      Parameters:
      composer - a composing function
      Returns:
      a composed consumer

    • compose

      Type Parameters:
      V - the mapped type
      Parameters:
      composer - a composing function

      Type Parameters:
      V1 - the former parameter type
      V2 - the latter parameter type
      Parameters:
      composer - a composing function
      Returns:
      a binary consumer that invokes this consumer using result of the specified binary function.

    • thenReturn

      default <R> LongFunction<R> thenReturn(Supplier<R> factory)
      Returns a function that returns the value from the specified supplier after accepting its parameter via this consumer.
      Type Parameters:
      R - the return type
      Parameters:
      factory - a factory of the function return value
      Returns:
      a function that returns the value from the specified supplier after accepting its parameter via this consumer.

    • thenReturnLong

      default LongUnaryOperator thenReturnLong(LongSupplier factory)
      Returns a function that returns the value from the specified supplier after accepting its parameter via this consumer.
      Parameters:
      factory - a factory of the function return value
      Returns:
      a function that returns the value from the specified supplier after accepting its parameter via this consumer.
