    • Method Detail

      • identity

      • fromGraph

        public <I1,​O1,​I2,​O2,​M> BidiFlow<I1,​O1,​I2,​O2,​M> fromGraph​(Graph<BidiShape<I1,​O1,​I2,​O2>,​M> g)
        A graph with the shape of a BidiFlow logically is a BidiFlow, this method makes it so also in type.

        public <I1,​O1,​I2,​O2,​M1,​M2,​M> BidiFlow<I1,​O1,​I2,​O2,​M> fromFlowsMat​(Graph<FlowShape<I1,​O1>,​M1> flow1,

        Wraps two Flows to create a ''BidiFlow''. The materialized value of the resulting BidiFlow is determined by the combiner function passed in the second argument list.

                                                                                                                   Function<I2,​O2> bottom)
        Create a BidiFlow where the top and bottom flows are just one simple mapping operator each, expressed by the two functions.
      • bidirectionalIdleTimeout

        public <I,​O> BidiFlow<I,​I,​O,​O,​NotUsed> bidirectionalIdleTimeout​(scala.concurrent.duration.FiniteDuration timeout)
        Deprecated.
        Use the overloaded one which accepts java.time.Duration instead. Since Akka 2.5.12.
        If the time between two processed elements *in any direction* exceed the provided timeout, the stream is failed with a BackpressureTimeoutException.

        There is a difference between this operator and having two idleTimeout Flows assembled into a BidiStage. If the timeout is configured to be 1 seconds, then this operator will not fail even though there are elements flowing every second in one direction, but no elements are flowing in the other direction. I.e. this operator considers the *joint* frequencies of the elements in both directions.
