NoOpEventTranslator Class Reference

#include <EventTranslator.h>

Inheritance diagram for NoOpEventTranslator:

List of all members.


Detailed Description

For completeness, if you want to have events be piped directly to the local erouter instead having to be encoded and decoded.

Unfortunately, this still entails a memory copy of the event since we have to make a new event for posting to the event router. We could avoid this if events were reference counted or if there was a way to direct the EventRouter not to free the event after processing.

Beware of subscribing this class as a listener to the same EventRouter that it is sending to -- could cause infinite recursion
