Interface AsyncFoldLeft.Operation<T,​R>

  • Type Parameters:
    T - the type of element
    R - the type of the result
    Enclosing class:
    Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    public static interface AsyncFoldLeft.Operation<T,​R>

    The operation to invoke for each element.

    • Method Detail

      • apply

        void apply​(R result,
                   T element,
                   AsyncFoldLeft.Loop<R> loop)

        Processes the given element.

        The processing of the element must produce a result that is the reduction of the accumulated result with the result of the processing of the given element.

        After the processing of the given element, the implementation must decide whether to continue with or break out of the iteration (with the reduced result) or to fail the iteration (with an exception).

        result - the accumulated result so far
        element - the element to process
        loop - the control object that continues or breaks the iteration
