ShutdownListener interface

public interface ShutdownListener

All members of ShutdownListener interface, including all inherited members.

Name	Description
shutdownPerformed method	Invoked before the ServerContext is destroyed due to server shutdown.

Use this interface to ensure that all threads, connections, and other resources are cleaned up before the MobiLink server exits.

The following example demonstrates how to install a ShutdownListener object for the ServerContext instance:

class MyShutdownListener implements ShutdownListener {
    FileOutputStream _outFile;
    public MyShutdownListener(FileOutputStream outFile) {
        _outFile = outFile;
    }

    public void shutdownPerformed(ServerContext sc) {
        // Add shutdown code
        try {
            _outFile.write(("Shutting Down" + "\n").getBytes());
            _outFile.flush();
        }
        catch(Exception e) {
            // Print some error output to the MobiLink log.
            e.printStackTrace();
        }
        // ...
    }
}

The following code registers a MyShutdownListener object. Call this code from anywhere that has access to the ServerContext such as a class constructor or synchronization script.

ServerContext serv_context;
FileOutputStream outFile;
serv_context.addShutdownListener(new MyShutdownListener(outFile));
