protected class DropTargetContext.TransferableProxy extends Objectimplements 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.

|---|---|
protected boolean |
isLocal
A
boolean indicating if the encapsulated
Transferable object represents the result of local drag-n-drop operation (within the same JVM).

transferable
The encapsulated
Transferable object.

getTransferData(DataFlavor
Returns an object which represents the data provided by the encapsulated transferable for the requested data flavor.
|

getTransferDataFlavors()
Returns an array of DataFlavor objects indicating the flavors the data can be provided in by the encapsulated transferable.
|

isDataFlavorSupported(DataFlavor
Returns whether or not the specified data flavor is supported by the encapsulated transferable.

false otherwise
public ObjectgetTransferData(DataFlavor df) throws UnsupportedFlavorException , IOException
In case of local transfer a serialized copy of the object returned by the encapsulated transferable is provided when the data is requested in application/x-java-serialized-object data flavor.

df - the requested flavor for the data
IOException - if the data is no longer available in the requested flavor.
UnsupportedFlavorException - if the requested data flavor is not supported.
