Public Functions

virtual void OnVisitNode(TNodeID const parent, const typename tree_t::TEdgeInfo &edge_to_child, size_t depth_level) = 0

Virtual method to be implemented by the user and which will be called during the visit to a graph with visitDepthFirst or visitBreadthFirst Specifically, the method will be called once for each edge in the tree.

Parameters:

  • parent – [IN] The ID of the parent node.

  • edge_to_child – [IN] The edge information from the parent to “edge_to_child.id”

  • depth_level – [IN] The “depth level” of the child node “edge_to_child.id” (root node is at 0, its children are at 1, etc.).
