fulmine.context
Interface IFTContextStateListener

All Superinterfaces:

IDestroyable, ILifeCycle

public interface IFTContextStateListener
extends ILifeCycle

Receives notifications when a fault tolerant context changes state; transitioning into the active or stand-by state. Implementations should perform the necessary resource allocation/de-allocation for the FT context instance transitioning into either of these states.

A state listener should not make any assumptions that once in the active state, the context will not go into stand-by; the context may switch between these states.
