Sawyer::Container::Algorithm::DepthFirstReverseVertexTraversal< Graph > Class Template Reference

Description

template<class Graph>
class Sawyer::Container::Algorithm::DepthFirstReverseVertexTraversal< Graph >

Depth-first, reverse traversal for vertices.

This traversal follows edges in their reverse order from target to source visiting child vertices before siblings. The advancing methods and operators (advance, next, etc.) stop only at vertex enter events (ENTER_VERTEX). Dereferencing the traversal object returns a graph vertex node.
