2436 :: Graph with multiple connections and different node types

• pkeeper (orginal) [2016-08-04T09:44:30+02:00] view original

  Hello. Newbie here. I'm trying to build graph with:

  • nodes of a different types
  • those types can have different fields, sometimes with same name
  • some nodes (types) should have arbitrary number of links to other nodes, of any type

  I'm having hard time to get how it should be done, especially the last one. Is there some kind of sequence of arbitrary type references, seq[ref], seq[any]? Or should I just make it with object variant method and put up with impossibility of objects variants to have same field name?

  Example of such a setup

  type
      Node = ref object of RootObj
          id: string
      
      Container = ref object of Node
          scope: seq[any] ?      # or at least seq[Node|Container|View] ?
      
      View = ref object of Node
          name: string
          initNode: ref any      # ?
          scope: seq[any]        # same
  Run

  If they are going to contain only Node and derivatives, you may use Node. I think this is what you want

  type
      Node = ref object of RootObj
          id: string
      
      Container = ref object of Node
          scope: seq[Node]
      
      View = ref object of Node
          name: string
          initNode: Node
          scope: seq[Node]
  Run

  This is an example using your code
