    • origin

      public QueryOrigin origin()
      Description copied from interface: GraphElement
      Contains provenance to tie back this GraphElement to the user code that defined it.

      This must be set when a GraphElement is directly created by some user code. Subsequently, this initial origin must be propagated as is without modification. If this GraphElement is copied or converted to a different type, then this origin must be copied as is.

      Specified by:
      origin in interface GraphElement
      Returns:
      (undocumented)
