KillSwitches

java.lang.Object
- akka.stream.KillSwitches

```
public class KillSwitches
extends java.lang.Object
```
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.

Modifier and Type	Method	Description
`static SharedKillSwitch`	`shared(java.lang.String name)`	Creates a new `SharedKillSwitch` with the given name that can be used to control the completion of multiple streams from the outside simultaneously.
`static <T> Graph<FlowShape<T,T>,UniqueKillSwitch>`	`single()`	Creates a new `Graph` of `FlowShape` that materializes to an external switch that allows external completion of that unique materialization.
`static <T1,T2> Graph<BidiShape<T1,T1,T2,T2>,UniqueKillSwitch>`	`singleBidi()`	Creates a new `Graph` of `FlowShape` that materializes to an external switch that allows external completion of that unique materialization.

  - single
```
public static <T> Graph<FlowShape<T,T>,UniqueKillSwitch> single()
```
    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.

    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.
