A
MarkerTransfer is used to transfer an array of
IMarkers from one part to another in a drag and drop operation.
In every drag and drop operation there is a DragSource and a
DropTarget. When a drag occurs a Transfer is used
to marshall the drag data from the source into a byte array. If a drop occurs
another Transfer is used to marshall the byte array into drop
data for the target.
This class can be used for a Viewer or an SWT component
directly. A singleton is provided which may be serially reused (see
getInstance). It is not intended to be subclassed.

- This class is not intended to be subclassed by clients.
