Class DropTargetContext.TransferableProxy

  • All Implemented Interfaces:
    Transferable
    Enclosing class:
    DropTargetContext


    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.
