Package 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.
