Examples of org.apache.mina.handler.demux.DemuxingIoHandler

org.apache.mina.handler.demux.DemuxingIoHandler
A {@link IoHandler} that demuxes messageReceived eventsto the appropriate {@link MessageHandler}.
You can freely register and deregister {@link MessageHandler}s using {@link #addReceivedMessageHandler(Class,MessageHandler)} and{@link #removeReceivedMessageHandler(Class)}.

When message is received through a call to {@link #messageReceived(IoSession,Object)} the class of themessage object will be used to find a {@link MessageHandler} forthat particular message type. If no {@link MessageHandler} instance can befound for the immediate class (i.e. message.getClass()) the interfaces implemented by the immediate class will be searched in depth-first order. If no match can be found for any of the interfaces the search will be repeated recursively for the superclass of the immediate class (i.e. message.getClass().getSuperclass()).

Consider the following type hierarchy (Cx are classes while Ix are interfaces):
```
 C3 - I7 - I9 |    |   /\ |   I8  I3 I4 | C2 - I5 - I6 | C1 - I1 - I2 - I4 |         | |        I3 Object 
```
When message is of type C3 this hierarchy will be searched in the following order: C3, I7, I8, I9, I3, I4, C2, I5, I6, C1, I1, I2, I3, I4, Object.

For efficiency searches will be cached. Calls to {@link #addReceivedMessageHandler(Class,MessageHandler)} and{@link #removeReceivedMessageHandler(Class)} clear this cache.
