mrpt::graphs::CDirectedTree< TYPE_EDGES > Class Template Reference

Detailed Description

template<class TYPE_EDGES = uint8_t>
class mrpt::graphs::CDirectedTree< TYPE_EDGES >

A special kind of graph in the form of a tree with directed edges and optional edge annotations of templatized type "TYPE_EDGES".

The tree is represented by means of:

• root: The ID of the root node.
• edges_to_children: A map from node ID to all the edges to its children.

This class is less general than CDirectedGraph but more efficient to traverse (see visitDepthFirst and visitBreadthFirst).

If annotations in edges are not required, you can leave TYPE_EDGES to its default type "uint8_t".
