Daemon

public Daemon()

Constructs the Daemon.

Method Detail

getContext

public DaemonContext getContext()

Get the context for this Daemon.

Returns:

DaemonContext

getEventService

public EventService getEventService()

Get the event service this daemon uses. By default, this daemon instance will use its own private event service.

Returns:

event service

setEventService

public void setEventService(EventService eventService)

Set the event service this daemon uses. By default, this daemon instance will use its own private event service.

Parameters:

eventService - event service

startup

public boolean startup()
                throws IOException

Starts the daemon, first calling the #configure(ConfigurationContext) method to allow your server to configure itself.

Returns:

true if at least one interface started, otherwise false.

Throws:

IOException

onStart

protected void onStart()
                throws IOException

Throws:

IOException

startListeningInterface

protected boolean startListeningInterface(ListeningInterface li)
                                   throws IOException

Throws:

IOException

removeAcceptor

public void removeAcceptor(ListeningInterface li)

isStarted

public boolean isStarted()

Get whether the daemon is currently started

Returns:

started

shutdown

public void shutdown()

Shutdown the server. This does not exit the JVM

onShutdown

protected void onShutdown()

registerConnector

public void registerConnector(ClientConnector connector,
                              SocketChannel socketChannel)
                       throws IOException

Register a client connector with the daemon.

Parameters:

connector - ClientConnector

socketChannel - SocketChannel

Throws:

IOException

registerAcceptor

public void registerAcceptor(ClientAcceptor acceptor,
                             ServerSocketChannel socketChannel)
                      throws IOException

Register a client acceptor with the daemon.

Parameters:

acceptor - ClientAcceptor

socketChannel - ServerSocketChannel

Throws:

IOException

registerHandler

public void registerHandler(SocketHandler handler,
                            SelectableChannel channel)
                     throws IOException

Register a socket handler with the daemon.

Parameters:

handler - SocketHandler

channel - SelectableChannel

Throws:

IOException

registerHandler

public void registerHandler(SocketHandler handler,
                            SelectableChannel channel,
                            SelectorThread thread)
                     throws IOException

Register a socket handler with the daemon.

Parameters:

handler - SocketHandler

channel - SelectableChannel

thread - SelectorThread

Throws:
