Method Detail

cancelRequests

protected void cancelRequests()
                       throws IOReactorException

Description copied from class: AbstractMultiworkerIOReactor

Triggered to cancel pending session requests.

Super-classes can implement this method to react to the event.

Specified by:

cancelRequests in class AbstractMultiworkerIOReactor

Throws:

IOReactorException - in case if a non-recoverable I/O error.

processEvents

protected void processEvents(int readyCount)
                      throws IOReactorException

Description copied from class: AbstractMultiworkerIOReactor

Triggered to process I/O events registered by the main Selector.

Super-classes can implement this method to react to the event.

Specified by:

processEvents in class AbstractMultiworkerIOReactor

Parameters:

readyCount - event count.

Throws:

IOReactorException - in case if a non-recoverable I/O error.

listen

public ListenerEndpoint listen(SocketAddress address)

Description copied from interface: ListeningIOReactor

Opens a new listener endpoint with the given socket address. Once the endpoint is fully initialized it starts accepting incoming connections and propagates I/O activity notifications to the I/O event dispatcher.

Specified by:

listen in interface ListeningIOReactor

Parameters:

address - the socket address to listen on.

Returns:

listener endpoint.

getEndpoints

public Set<ListenerEndpoint> getEndpoints()

Description copied from interface: ListeningIOReactor

Returns a set of endpoints for this I/O reactor.

Specified by:

getEndpoints in interface ListeningIOReactor

Returns:

set of endpoints.

pause

public void pause()
           throws IOException

Description copied from interface: ListeningIOReactor

Suspends the I/O reactor preventing it from accepting new connections on all active endpoints.

Specified by:

pause in interface ListeningIOReactor

Throws:

IOException - in case of an I/O error.

resume

public void resume()
            throws IOException

Description copied from interface: ListeningIOReactor

Resumes the I/O reactor restoring its ability to accept incoming connections on all active endpoints.

Specified by:

resume in interface ListeningIOReactor

Throws:

IOException - in case of an I/O error.
