Interface LongConsumer

  • All Known Subinterfaces:
    All Known Implementing Classes:
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    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).

      • accept

        void accept​(long value)
        Performs this operation on the given argument.
        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.
        after - the operation to perform after this operation
        a composed LongConsumer that performs in sequence this operation followed by the after operation
        NullPointerException - if after is null
