java.awt.dnd.DropTargetContext.TransferableProxy
- All Implemented Interfaces:
- Transferable
- Enclosing class:
- DropTargetContext
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.

Method Details- 
getTransferDataFlavorsReturns an array of DataFlavor objects indicating the flavors the data can be provided in by the encapsulated transferable.- Specified by:
- getTransferDataFlavorsin interface- Transferable
- Returns:
- an array of data flavors in which the data can be provided by the encapsulated transferable
 
- 
isDataFlavorSupportedReturns whether or not the specified data flavor is supported by the encapsulated transferable.- Specified by:
- isDataFlavorSupportedin interface- Transferable
- Parameters:
- flavor- the requested flavor for the data
- Returns:
- trueif the data flavor is supported,- falseotherwise
 
- 
getTransferDataReturns an object which represents the data provided by the encapsulated transferable for the requested data flavor.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. - Specified by:
- getTransferDatain interface- Transferable
- Parameters:
- df- the requested flavor for the data
- Returns:
- an object which represents the data to be transferred
- Throws:
- IOException- if the data is no longer available in the requested flavor.
- UnsupportedFlavorException- if the requested data flavor is not supported.
