protected class DropTargetContext.TransferableProxy extends Object implements Transferable
TransferableProxy is a helper inner class that implements
Transferable interface and serves as a proxy for another
Transferable object which represents data transfer for
a particular drag-n-drop operation.
The proxy forwards all requests to the encapsulated transferable and automatically performs additional conversion on the data returned by the encapsulated transferable in case of local transfer.
