ContinuationState (Apache Synapse - Core 4.0.0-wso2v53 API)

All Known Implementing Classes:

AbstractContinuationState, ReliantContinuationState, SeqContinuationState
```
public interface ContinuationState
```
Implementations of this interface holds the runtime state information of important checkpoints of the mediation flow. This information is mainly used to mediate the response message when service is invoked using the Call Mediator. Instances of ContinuationState are stored in the ContinuationState Stack which resides in the MessageContext
