java.lang.Objectjava.awt.dnd.DropTargetContext.TransferableProxy
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.
| Field Summary | |
protected boolean |
isLocal
A boolean indicating if the encapsulated
Transferable object represents the result
of local drag-n-drop operation (within the same JVM). |
protected Transferable |
transferable
The encapsulated Transferable object. |
| Method Summary | |
Object |
getTransferData(DataFlavor df)
Returns an object which represents the data provided by the encapsulated transferable for the requested data flavor. |
DataFlavor[] |
getTransferDataFlavors()
Returns an array of DataFlavor objects indicating the flavors the data can be provided in by the encapsulated transferable. |
boolean |
isDataFlavorSupported(DataFlavor flavor)
Returns whether or not the specified data flavor is supported by the encapsulated transferable. |

protected Transferable transferable
Transferable object.
protected boolean isLocal
boolean indicating if the encapsulated

| Method Detail |
public DataFlavor[] getTransferDataFlavors()
getTransferDataFlavors in interface Transferablepublic boolean isDataFlavorSupported(DataFlavor flavor)
isDataFlavorSupported in interface Transferableflavor - the requested flavor for the data
true if the data flavor is supported,
false otherwise
public Object getTransferData(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.
getTransferData in interface Transferabledf - 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.DataFlavor.getRepresentationClass()
