KillSwitches

object KillSwitches

Creates shared or single kill switches which can be used to control completion of graphs from the outside.

  • The factory shared() returns a SharedKillSwitch which provides a Graph of FlowShape that can be used in arbitrary number of graphs and materializations. The switch simultaneously controls completion in all of those graphs.
  • The factory single() returns a Graph of FlowShape that materializes to a UniqueKillSwitch which is always unique to that materialized Flow itself.

Creates a SharedKillSwitch that can be used to externally control the completion of various streams.

  2. def single[T]: Graph[FlowShape[T, T], UniqueKillSwitch]

    Creates a new Graph of FlowShape that materializes to an external switch that allows external completion of that unique materialization.

    Creates a new Graph of FlowShape that materializes to an external switch that allows external completion of that unique materialization. Different materializations result in different, independent switches.

  3. def singleBidi[T1, T2]: Graph[BidiShape[T1, T1, T2, T2], UniqueKillSwitch]

    Creates a new Graph of FlowShape that materializes to an external switch that allows external completion of that unique materialization.

    Creates a new Graph of FlowShape that materializes to an external switch that allows external completion of that unique materialization. Different materializations result in different, independent switches.
