Class ResourceTransfer


  • public class ResourceTransfer
    extends ByteArrayTransfer
    The ResourceTransfer class is used to transfer an array of IResources from one part to another in a drag and drop operation or a cut, copy, paste action.

    In every drag and drop operation there is a DragSource and a DropTarget. When a drag occurs a Transfer is used to marshal the drag data from the source into a byte array. If a drop occurs another Transfer is used to marshal the byte array into drop data for the target.

    When a CutAction or a CopyAction is performed, this transfer is used to place references to the selected resources on the Clipboard. When a PasteAction is performed, the references on the clipboard are used to move or copy the resources to the selected destination.

    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.

    The amount of resources which can be transferred is limited to MAX_RESOURCES_TO_TRANSFER elements.
