All Implemented Interfaces:

ChangeCommand

public class DuplicateSubtreeCommand
extends java.lang.Object
implements ChangeCommand

This command will replicate a subtree in the source version of an OWL Mapping graph. In other words, it can only accept Nodes of a few types... namely, MemberOfNodes, RestrictedNodes, WalkedToObjectNodes, WalkedToDataNodes and RestrictedNodes. Eventually, and if this proves useful, I may provide a method on OWLMappingNodes to duplicate() them.

The user must replicate the Node that is being duplicated and altered. I see the main usage of this to select a restricted node, alter one of the restrictions (selecting a different set of rows from a table) but then duplicating the relationships which will be standard across all rows of the table. To achieve this, the client will create a new node with the altered restriction, then supply the one being copied and the new node. This method then attaches this new node and replicates the entire subtree, attaching the supplied prefix to all nodes in the tree.
