  • abstract class GraphStageLogic extends AnyRef

    Represents the processing logic behind a GraphStage.

    Represents the processing logic behind a GraphStage. Roughly speaking, a subclass of GraphStageLogic is a collection of the following parts: * A set of InHandler and OutHandler instances and their assignments to the Inlets and Outlets of the enclosing GraphStage * Possible mutable state, accessible from the InHandler and OutHandler callbacks, but not from anywhere else (as such access would not be thread-safe) * The lifecycle hooks preStart() and postStop() * Methods for performing stream processing actions, like pulling or pushing elements

    The stage logic is completed once all its input and output ports have been closed. This can be changed by setting setKeepGoing to true.

    The postStop lifecycle hook on the logic itself is called once all ports are closed. This is the only tear down callback that is guaranteed to happen, if the actor system or the materializer is terminated the handlers may never see any callbacks to onUpstreamFailure, onUpstreamFinish or onDownstreamFinish. Therefore stage resource cleanup should always be done in postStop.

class SubSinkInlet[T] extends AnyRef

INTERNAL API

This allows the dynamic creation of an Inlet for a GraphStage which is connected to a Sink that is available for materialization (e.g. using the subFusingMaterializer). Care needs to be taken to cancel this Inlet when the stage shuts down lest the corresponding Sink be left hanging.
