Interface IOProcessor

public interface IOProcessor

This interface is used by the Send to send events from FSM and to receive events from external systems (FSM receives events and sends messages).
It will be associated with a state machine engine so the FSM context could find this processor in order to send messages to external resources (or another sessions) and the IOProcessor could use the engine to send events to the FSM.

Method Detail

getName

String getName()

Returns:

the name of this IO processor

getLocation

URI getLocation(String sessionId)

Parameters:

sessionId - session id

Returns:

the uri that the receiver could use to send an event back to the FSM.

sendMessageFromFSM
