org.eclipse.swt.dnd
Class TransferData

java.lang.Object
  org.eclipse.swt.dnd.TransferData

public class TransferData

extends Object

The TransferData class is a platform specific data structure for describing the type and the contents of data being converted by a transfer agent.

As an application writer, you do not need to know the specifics of TransferData. TransferData instances are passed to a subclass of Transfer and the Transfer object manages the platform specific issues. You can ask a Transfer subclass if it can handle this data by calling Transfer.isSupportedType(transferData).

You should only need to become familiar with the fields in this class if you are implementing a Transfer subclass and you are unable to subclass the ByteArrayTransfer class.

Field Summary

org.eclipse.swt.internal.ole.win32.FORMATETC	formatetc The formatetc structure is a generalized data transfer format, enhanced to encompass a target device, the aspect, or view of the data, and a storage medium.
int	pIDataObject The pIDataObject is the address of an IDataObject OLE Interface which provides access to the data associated with the transfer.
int	result The result field contains the result of converting a java data type into a platform specific value.
org.eclipse.swt.internal.ole.win32.STGMEDIUM	stgmedium The stgmedium structure is a generalized global memory handle used for data transfer operations.
int	type The type is a unique identifier of a system format or user defined format.
