public abstract class AbstractGlobalActionHandlerProvider
extends AbstractProvider
implements IGlobalActionHandlerProvider
extends AbstractProvider
implements IGlobalActionHandlerProvider

The abstract parent of all concrete global action handler providers. A concrete provider needs to override the getGlobalActionHandler() method only. The provides() method has a default implementation. The provides() method is already handled by the proxy for the provider (GlobalActionHandlerService.ProviderDescriptor). The proxy contains all the information necessary to decide handle the provides() method.
