Class AbstractContributionFactory

Direct Known Subclasses:

public abstract class AbstractContributionFactory extends Object
ContributionFactories are used by the IMenuService to populate ContributionManagers. In createContributionItems(IServiceLocator, IContributionRoot) you fill in the additions List with IContributionItem to be inserted at this factory's location. For example:
 AbstractContributionFactory contributions = new AbstractContributionFactory(
                "menu:org.eclipse.ui.tests.api.MenuTestHarness?after=additions") {
        public void createContributionItems(IMenuService menuService, List additions) {
                CommandContributionItem item = new CommandContributionItem("org.eclipse.ui.tests.menus.helloWorld",
                                "org.eclipse.ui.tests.commands.enabledHelloWorld", null, null, "Say Hello", null);
                item = new CommandContributionItem("org.eclipse.ui.tests.menus.refresh",
                                "org.eclipse.ui.tests.commands.refreshView", null, null, "Refresh", null);
                menuService.registerVisibleWhen(item, new MyActiveContextExpression("org.eclipse.ui.tests.myview.context"));

        public void releaseContributionItems(IMenuService menuService, List items) {
                // we have nothing to do
 IMenuService service = (IMenuService) PlatformUI.getWorkbench().getService(IMenuService.class);

Clients who are providing factories via the org.eclipse.ui.menus extension point should subclass ExtensionContributionFactory instead.

Only the abstract methods may be implemented.

      public AbstractContributionFactory(String location, String namespace)
      The contribution factories must be instantiated with their location, which which specifies the contributions insertion location.

    • createContributionItems

      public abstract void createContributionItems(IServiceLocator serviceLocator, IContributionRoot additions)
      This factory should create the IContributionItems that it wants to contribute, and add them to the additions list. The menu service will call this method at the appropriate time. It should always return new instances of its contributions in the additions list.

      This method is not meant to be called by clients. It will be called by the menu service at the appropriate time.

      serviceLocator - a service locator that may be used in the construction of items created by this factory
      additions - A IContributionRoot supplied by the framework. It will never be null.
