com.sun.enterprise.web.connector.grizzly.comet.CometHandler

This interface represents a suspended connection (or response). Passing an instance of this class to {@link CometContext.addCometListener} automaticallytells Grizzly Comet to suspend the underlying connection and to avoid commiting the response. Since the response is not commited, the connection is considered as suspended and can be resumed later when an event happens by invoking, from {@link #onEvent} or eveyrwhere, the {@link CometContext#resumeCometHandler}, which resume the connection by commiting the response. As an example, a browser icons will spins when a connection is suspended, as the complete response hasn't been sent back. Components that implement this interface will be notified when another {@link CometHandler} notify them using {@link CometContext#notify}With Servlet, it is recommended to attach the {@link HTTPServletResponse}and use this object to push back messages to the client. @author Jeanfrancois Arcand
