struct mrpt::graphs::CDirectedTree::Visitor

Virtual base class for user-defined visitors.

Obsolete: Prefer C++11 visitor_t

#include <mrpt/graphs/CDirectedTree.h>

struct Visitor
{
    // typedefs

    typedef CDirectedTree<TYPE_EDGES> tree_t;

methods

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

Methods

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.).
