public void onEvent(final CometEvent<E> event) throws IOException

Implements org.glassfish.grizzly.comet.CometHandler.onEvent.

Doc from org.glassfish.grizzly.comet.CometHandler.onEvent.

Receive CometEvent notification. This method will be invoked every time a CometContext#notify is invoked. The CometEvent will contains the message that can be pushed back to the remote client, cached or ignored. This method can also be used to resume a connection once a notified by invoking CometContext#resumeCometHandler.
its not optimal to flush outputstream in this method for long polling, flush is performed in each CometContext.resume call.
flushing multiple times can fragment the data into several tcp packets, that leads to extra IO and overhead in general due to client ack for each packet etc.

public void onInitialize(final CometEvent<E> event) throws IOException

Implements org.glassfish.grizzly.comet.CometHandler.onInitialize.

Doc from org.glassfish.grizzly.comet.CometHandler.onInitialize.

Receive CometEvent notification when Grizzly is about to suspend the connection. This method is always invoked during the processing of CometContext#addCometHandler operations.

public void onInterrupt(final CometEvent<E> event) throws IOException

Implements org.glassfish.grizzly.comet.CometHandler.onInterrupt.

Doc from org.glassfish.grizzly.comet.CometHandler.onInterrupt.

Receive CometEvent notification when the underlying tcp communication is resumed by Grizzly. This happens when the CometContext#setExpirationDelay expires or when the remote client close the connection.
