Class AbstractTransferAdapterProvider

java.lang.Object
  

org.eclipse.gmf.runtime.common.core.service.AbstractProvider
      
org.eclipse.gmf.runtime.common.ui.services.dnd.core.AbstractTransferAdapterProvider

All Implemented Interfaces:

IProvider, org.eclipse.gmf.runtime.common.ui.services.dnd.internal.core.ITransferAdapterProvider

---

public class AbstractTransferAdapterProvider
extends 
AbstractProvider
implements org.eclipse.gmf.runtime.common.ui.services.dnd.internal.core.ITransferAdapterProvider

The abstract parent of all concrete transfer adapter providers. A concrete provider needs to override the getTransferDragSourceAdapter() and getTransferDropTargetAdapter methods. The provides method has a default implementation. The provides() method is already handled by the proxy for the provider (TransferAdapterService.ProviderDescriptor). The proxy contains all the information necessary for the provides() method.
