Package Summary  Overview Summary

class:DropTargetContext.TransferableProxy [NONE]

  • 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:transferable [NONE]

  • transferable

    protected Transferable transferable
    The encapsulated Transferable object.

field:isLocal [NONE]

  • 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:getTransferDataFlavors() [NONE]

  • 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

method:isDataFlavorSupported(java.awt.datatransfer.DataFlavor) [NONE]

  • 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

method:getTransferData(java.awt.datatransfer.DataFlavor) [NONE]

  • 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
    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.
