| Runtime application model</H2> |
| <p> The platform runtime provides an application container for controlling and executing |
| applications. The runtime application container implements the Application Admin |
| service specification included in the OSGi R7 specification. The application container is |
| responsible for discovering all available applications and registering an |
| <a href="https://docs.osgi.org/javadoc/osgi.cmpn/7.0.0/org/osgi/service/application/ApplicationDescriptor.html"> |
| ApplicationDescriptor</a> OSGi service for each application that is available. An ApplicationDescriptor |
| service can be used to launch an application. When an application is launched an |
| <a href="https://docs.osgi.org/javadoc/osgi.cmpn/7.0.0/org/osgi/service/application/ApplicationHandle.html"> |
| ApplicationHandle</a> OSGi service is registered to represent the instance of the running |
| application. An ApplicationHandle service can be used to shutdown an application. |
| See the <a href="https://docs.osgi.org/javadoc/osgi.cmpn/7.0.0/org/osgi/service/application/package-summary.html">org.osgi.service.application</a> |
| package and the <a href="https://docs.osgi.org/specification/osgi.cmpn/7.0.0/service.application.html">Application Admin Specification</a> for more |
| information. |
| </p> |
| <h3> |
| The default application |
| </h3> |
| <p> |
| A given Eclipse configuration may contain many products and applications. An Eclipse configuration |
| specifies a default application which is launched by the application container as soon as the platform |
| runtime is up and running. The default application can be specified by one of the following |
| configuration options</p> |
| <ul> |
| <li><a href="../reference/misc/runtime-options.html#eclipseproduct">eclipse.product</a> - |
| identifies the product to launch the platform runtime with. A product supplies branding information |
| (window icons, title bar text etc.) as well as defining the default application to run.</li> |
| <li><a href="../reference/misc/runtime-options.html#eclipseapplication">eclipse.application</a> - |
| identifies the application to launch the platform runtime with. This option overrides default application |
| defined by the product.</li> |
| </ul> |
| |
| <h3> |
| Defining an application |
| </h3> |
| <p> |
| Plug-ins may define their own applications using the |
| <a href="../reference/extension-points/org_eclipse_core_runtime_applications.html"><b>org.eclipse.core.runtime.applications</b></a> |
| extension. In this extension, the plug-in defines the name and ID of the application, as well a class that implements |
| the application. The class which implements the application is used to launch and shutdown application instances. |
