public class MarkerTransfer extends ByteArrayTransfer
AMarkerTransferis used to transfer an array ofIMarkers from one part to another in a drag and drop operation.In every drag and drop operation there is a
DragSourceand aDropTarget. When a drag occurs aTransferis used to marshall the drag data from the source into a byte array. If a drop occurs anotherTransferis used to marshall the byte array into drop data for the target.This class can be used for a
Vieweror an SWT component directly. A singleton is provided which may be serially reused (seegetInstance). It is not intended to be subclassed.- See Also:
StructuredViewer,DropTarget,DragSource- Restriction:
- This class is not intended to be subclassed by clients.
