StateContext

All Known Implementing Classes:

AbstractStateContext, DefaultStateContext
```
public interface StateContext
```
StateContext objects are used to store the current State and any application specific attributes for a specific client of a StateMachine. Since StateMachines are singletons and shared by all clients using the StateMachine this is where client specific data needs to be stored.
