Method Detail

getCount

public int getCount()

Get the number of transferred elements.

Returns:

the count

getTransferableAt

public Transferable getTransferableAt(int index)

Get the transferable at some index.

Parameters:

index - the index

Returns:

the transferable

isDataFlavorSupported

public boolean isDataFlavorSupported(int index,
                                     DataFlavor flavor)

Test whether a given data flavor is supported by the item at index.

Parameters:

index - the index

flavor - the flavor to test

Returns:

true if the flavor is supported

areDataFlavorsSupported

public boolean areDataFlavorsSupported(DataFlavor[] array)

Test whether each transferred item supports at least one of these flavors. Different items may support different flavors, however.

Parameters:

array - array of flavors

Returns:

true if all items support one or more flavors

getTransferDataFlavors

public DataFlavor[] getTransferDataFlavors(int i)

Get list of all supported flavors for the item at an index.

Parameters:

i - the index

Returns:

array of supported flavors

getTransferData

public Object getTransferData(int indx,
                              DataFlavor flavor)
                       throws UnsupportedFlavorException,
                              IOException

Get transfer data for the item at some index.

Parameters:

indx - the index

flavor - the flavor desired

Returns:

transfer data for item at that index

Throws:

IOException - if there is an I/O problem

UnsupportedFlavorException - if that flavor is not supported
