Class PluginTransfer


  • public class PluginTransfer
    extends ByteArrayTransfer
    This class can be used to transfer an instance of PluginTransferData between two parts in a workbench 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.

    A PluginTransferData contains the id of a drop action extension. If a drop occurs the extension is invoked to perform a drop action. As a benefit, the destination viewer doesn't need to have any knowledge of the items being dropped into it.

    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.
