Class HierarchicalTreePasteDataCommandHandler

All Implemented Interfaces:

public class HierarchicalTreePasteDataCommandHandler extends RowSpanningPasteDataCommandHandler
ILayerCommandHandler for handling PasteDataCommands using the InternalCellClipboard on a HierarchicalTreeLayer. Will treat cells with row spanning as a single cell. Will also not copy cells of collapsed nodes if the labels HierarchicalTreeLayer.COLLAPSED_CHILD or HierarchicalTreeLayer.NO_OBJECT_IN_LEVEL are applied.

To work correctly the HierarchicalTreeCopyDataCommandHandler should be registered for handling copy operations with the InternalCellClipboard, or at least the HierarchicalTreeLayer should be set as copyLayer to ensure the additional information added by the HierarchicalTreeLayer can be inspected as the cells to copy are collected on that layer and not the SelectionLayer.
