API information:
The value of the class attribute must represent a subclass of org.
eclipse.gmf.runtime.common.core.service.AbstractProvider that
implements org.eclipse.gmf.runtime.common.ui.services.dnd.
core.IDragDropListenerProvider (such as a subclass of org.eclipse.
gmf.runtime.common.ui.services.dnd.core. AbstractDragDrop
ListenerProvider ).
Notes:
Diagrams generated using the GMF tooling do not currently use this
extension-point.
10.4.19 TransferAdapterService
The TransferAdapterService and corresponding ITransferAdapter
|Provider interface allow providers to supply transfer adapters for a specified
transfer ID during drag-and-drop operations. An AbstractTransfer
AdapterProvider is supplied, along with a concrete TransferAdapter
Provider class, as seen in Figure 10-43. Providers work with ITransfer
DropTargetListener and ITransferDragSourceListener implemen-
tations.
