public interface IChannelTarget

Defines an interface to trigger client updates on server side events.

This interface is very similar to the API of the AjaxRequestTarget, so users already familiar with AjaxRequestTarget should easily find their way with this interface.

A IChannelTarget implementation can be used in IChannelListener implementations.
