DropTargetContext.TransferableProxy (Java Platform SE 7 b138)

java.lang.Object
- java.awt.dnd.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.

Field Summary

Fields
Modifier and Type	Field and Description
`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

Methods
Modifier and Type	Method and Description
`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.

- Field Detail
  - transferable
```
protected Transferable transferable
```
    The encapsulated Transferable object.
  - isLocal
```
protected boolean isLocal
```
    A boolean indicating if the encapsulated Transferable object represents the result of local drag-n-drop operation (within the same JVM).
- Method Detail
  - getTransferDataFlavors
```
public DataFlavor[] getTransferDataFlavors()
```
    Returns an array of DataFlavor objects indicating the flavors the data can be provided in by the encapsulated transferable.
    
    Specified by:
    
    getTransferDataFlavors in interface Transferable
    
    Returns:
    an array of data flavors in which the data can be provided by the encapsulated transferable
  - isDataFlavorSupported
```
public boolean isDataFlavorSupported(DataFlavor flavor)
```
    Returns whether or not the specified data flavor is supported by the encapsulated transferable.
    
    Specified by:
    
    isDataFlavorSupported in interface Transferable
    
    Parameters:
    flavor - the requested flavor for the data
    
    Returns:
    true if the data flavor is supported, false otherwise
  - getTransferData
```
public Object getTransferData(DataFlavor df)
                       throws UnsupportedFlavorException,
                              IOException
```
    Returns 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:
    
    getTransferData in interface Transferable
    
    Parameters:
    df - the requested flavor for the data
    
    Throws:
    
    IOException - if the data is no longer available in the requested flavor.
    
    UnsupportedFlavorException - if the requested data flavor is not supported.
