I am trying to create my own persistence in a database. I had two questions:
- How do I determine the start node for a GoDoc without having to determine which GraphNode has no pidin? After using the ProtoApp sample, I was convinced that the order in which the Store method writes the xml file is based on the order in which the Icon/text nodes are dragged & dropped. So if I dragged the first node last it is last in the iteration of the collection.
- From a given node how can I determine which is the next node without having to look at the link from's and to's?
