Class DefaultListeningIOReactor

java.lang.Object
  org.apache.http.impl.nio.reactor.AbstractMultiworkerIOReactor
      org.apache.http.impl.nio.reactor.DefaultListeningIOReactor

All Implemented Interfaces:

IOReactor, ListeningIOReactor

public class DefaultListeningIOReactor
extends AbstractMultiworkerIOReactor
implements ListeningIOReactor

Default implementation of ListeningIOReactor. This class extends AbstractMultiworkerIOReactor with capability to listen for incoming connections.

The following parameters can be used to customize the behavior of this class:

• CoreConnectionPNames.TCP_NODELAY
• CoreConnectionPNames.SO_TIMEOUT
• CoreConnectionPNames.SO_LINGER
• NIOReactorPNames.SELECT_INTERVAL
• NIOReactorPNames.GRACE_PERIOD
• NIOReactorPNames.INTEREST_OPS_QUEUEING

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.

ListenerEndpoint.waitFor() can be used to wait for the listener to be come ready to accept incoming connections.

ListenerEndpoint.close() can be used to shut down the listener even before it is fully initialized.

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.
