Provides a set of classes that implement a `Service` that provides an extensible way to handle commonly used (global) actions in different views and editors. When a `GlobalAction` is registered as the action handler for a retargetable action in a given workbench part, the {@link org.eclipse.gmf.runtime.common.ui.services.action.global.GlobalActionHandlerService} is consulted to do the real work in running the action. The service allows different handlers to be used depending on the nature of the element(s) selected in the workbench part.

Global actions are action handlers for Eclipse retargetable actions. The real action handler work is delegated to the {@link org.eclipse.gmf.runtime.common.ui.services.action.global.IGlobalActionHandler}s provided by the {@link org.eclipse.gmf.runtime.common.ui.services.action.global.GlobalActionHandlerService} for the active workbench part.

In order to contribute global action handlers to the service, clients should use the `org.eclipse.gmf.runtime.common.ui.services.action.globalActionHandlerProviders` extension point. The provider implementation specified in the extension point should subclass the {@link org.eclipse.gmf.runtime.common.ui.services.action.global.AbstractGlobalActionHandlerProvider} class in this package.

Modeling platform global action handlers should subclass the {@link org.eclipse.gmf.runtime.common.ui.services.action.global.AbstractGlobalActionHandler} class.
