java.lang.Objectorg.eclipse.gmf.runtime.common.core.service.AbstractProvider
org.eclipse.gmf.runtime.common.ui.services.dnd.core.AbstractDragDropListenerProvider
public abstract class AbstractDragDropListenerProvider
The abstract parent of all concrete drag and drop listener providers. A
concrete provider needs to override the getDragSourceListener()
and getDropTargetListener methods. The provides
method has a default implementation. The provides() method is
already handled by the proxy for the provider (
DragDropListenerService.ProviderDescriptor). The proxy
contains all the information necessary for the provides()
method.
