protected class DropTargetContext.TransferableProxy extends Object implements Transferable
TransferableProxyis a helper inner class that implements
Transferableinterface and serves as a proxy for another
Transferableobject 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.
