Package com.yahoo.jdisc.application

Class AbstractApplication

java.lang.Object

com.yahoo.jdisc.application.AbstractApplication

All Implemented Interfaces:

Application

Direct Known Subclasses:

AbstractClientApplication

public abstract class AbstractApplication
extends java.lang.Object
implements Application

This class is a convenient parent class for Application developers that require simple access to the most commonly used jDISC APIs.

A simple hello world application could be implemented like this:

 class HelloApplication extends AbstractApplication {

     @Inject
     public HelloApplication(BundleInstaller bundleInstaller, ContainerActivator activator,
                             CurrentContainer container) {
         super(bundleInstaller, activator, container);
     }

     @Override
     public void start() {
         ContainerBuilder builder = newContainerBuilder();
         ServerProvider myServer = new MyHttpServer();
         builder.serverProviders().install(myServer);
         builder.serverBindings().bind("http://*/*", new MyHelloWorldHandler());

         activateContainer(builder);
         myServer.start();
         myServer.release();
     }
 }

AbstractApplication

@Inject
protected AbstractApplication(BundleInstaller bundleInstaller,
                              ContainerActivator activator,
                              CurrentContainer container)

Method Detail

stop

public void stop()

Description copied from interface: Application

This method is called by the ApplicationLoader after the corresponding signal has been issued by the controlling start script. Once this method returns, all calls to ContainerActivator.activateContainer(ContainerBuilder) will throw ApplicationNotReadyExceptions. Use this method to prepare for termination (see Application.destroy()).

Specified by:

stop in interface Application

destroy

public final void destroy()

Description copied from interface: Application

This method is called by the ApplicationLoader after first calling Application.stop(), and all previous DeactivatedContainers have terminated. Use this method to shut down all Application components such as ClientProviders and ServerProviders.

Specified by:

destroy in interface Application
