public class MarkerTransfer extends ByteArrayTransfer
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.
