Examples of org.jboss.dna.graph.request.CloneBranchRequest

org.jboss.dna.graph.request.CloneBranchRequest
Instruction that a branch be cloned from one workspace into another. Cloning a branch differs from cloning a branch in that:
1. Nodes can be cloned within the same workspace or to another workspace; cloned nodes must be cloned from one workspace into another.
2. Copied nodes always get new UUIDs; cloned nodes always maintain their UUIDs and hence must define the behavior that occurs if a node with the same UUID already exists in the new workspace.
3. Nodes can be cloned to a specific name under a specific parent, but can only be added as a new child node at the end of the new parent's children; nodes can be cloned to an exact location among the parent's children, replacing the existing node at that location.
