util::UndirectedAdjacencyListsOfDirectedGraph< Graph > Class Template Reference

This can be used to view a directed graph (that supports reverse arcs) from graph.h as un undirected graph: operator[](node) returns a pseudo-container that iterates over all nodes adjacent to "node" (from outgoing or incoming arcs). More...

Detailed Description

template<class Graph>
class util::UndirectedAdjacencyListsOfDirectedGraph< Graph >

This can be used to view a directed graph (that supports reverse arcs) from graph.h as un undirected graph: operator[](node) returns a pseudo-container that iterates over all nodes adjacent to "node" (from outgoing or incoming arcs).

CAVEAT: Self-arcs (aka loops) will appear twice.

Example: ReverseArcsStaticGraph<> dgraph; ... UndirectedAdjacencyListsOfDirectedGraph<decltype(dgraph)> ugraph(dgraph); for (int neighbor_of_node_42 : ugraph[42]) { ... }
