/**
* Allows a listener to be notified when an important channel lifecycle event occurs.
*
*
* Usually clients do not need to implement ChannelListener interface. However, this interface can
* useful in scenarios when an application opens multiple channels and needs to tracks major
* lifecycle events on those channels from a single location or in scenarios when channel is wrapped
* by JGroups building block installed on top of a channel (RpcDispatcher etc) while a client needs
* to be notified about major channel lifecycle events.
