public AbstractThreadedServer()

Method Detail

start

public void start()

Description copied from interface: Server

Starts the server as a separate thread.

stop

public void stop()

Description copied from interface: Server

Stops the server closes all created connections listed in its internal list of connections.

isRunning

public boolean isRunning()

Checks whenever the server thread is currently active.

The default way of determining if the server is running, is to check if the thread is running. Subclasses may overwrite this, if their thread could also be running even if they are not 'officially' running (e.g. 'stop' as been requested, but their thread needs to keep running).

Returns:

true if server thread is running, false otherwise.

isThreadAlive

protected final boolean isThreadAlive()

Return true of the server thread is running.

Returns:

true of the server thread is running

setStopRequested

protected final void setStopRequested(boolean stopRequested)

Server method to stop during next cycle.

Parameters:

stopRequested - true if server should stop.

isStopRequested

protected final boolean isStopRequested()

Server specific method to check if server is going to stop.

Returns:

True if server is going to stop, false otherwise.

serverThread

protected abstract void serverThread()

Implement the server thread!
