                  DockStation child)

Description copied from interface: Merger

Moves all children of child to parent, leaving child empty. This method is only called if canMerge returned true and if the accept-methods allow the operation.
If the parent of child is not parent, then child will be removed from its parent. Otherwise the child remains, allowing this Merger to reuse it.
