Examples of org.cometd.bayeux.client.ClientSessionChannel

org.cometd.bayeux.client.ClientSessionChannel
A client side channel representation.

A {@link ClientSessionChannel} is scoped to a particular {@link ClientSession}that is obtained by a call to {@link ClientSession#getChannel(String)}.

Typical usage examples are:
```
 clientSession.getChannel("/foo/bar").subscribe(mySubscriptionListener); clientSession.getChannel("/foo/bar").publish("Hello"); clientSession.getChannel("/meta/*").addListener(myMetaChannelListener); 
```
