def build_graph!
  # We build the graph without doing any actual execution:
  nodes = []

  walker = walk do |walker, node|
    nodes << node
  
    yield walker, node
  end

  traverse! walker

  # We should update the status of all nodes in the graph once we've traversed the graph.
  nodes.each do |node|
    node.update_status!
  end
end

#traverse!(walker) ⇒ Object

You need to override this to traverse the top nodes as required:
