Class CopyBranchRequest

      org.modeshape.graph.request.Request

All Implemented Interfaces:
  Serializable, Cloneable

    public class CopyBranchRequest

extends ChangeRequest

Instruction that a branch be copied from one location into another. This request can copy a branch in one workspace into another workspace, or it can copy a branch in the same workspace. Copying a branch always results in the generation of new UUIDs for the copied nodes. `Cloning a branch` provides functionality similar to copy, but with the ability to preserve UUIDs in the move.

  `CloneBranchRequest`, Serialized Form
