Examples of org.eclipse.ecf.datashare.IChannelListener

org.eclipse.ecf.datashare.IChannelListener
Listener for receiving messages sent to a given channel. The following types of events may be received asynchronously via this listener:
IChannelMessageEvent - delivered when this channel receives a message.
IChannelConnectEvent - delivered when this container or other remote containers connect.
IChannelDisconnectEvent - delivered when this channel or other remote containers disconnect.

Note these methods will be called asynchronously when notifications of remote changes are received by the provider implementation code. The provider is free to call the methods below with an arbitrary thread, so the implementation of these methods must be appropriately prepared.

For example, if the code implementing any of these methods must interact with user interface code, then it should use code such as the following to execute on the SWT UI thread:
```
 Display.getDefault().asyncExec(new Runnable() { public void run() { ... UI code here } }); 
```
Further, the code in the implementations of these methods should not block via I/O operations or blocking UI calls.
