#include <graph.h>

Public Types
using	NodeIndex
	The index type for nodes of the graph.

Detailed Description

template<typename Graph>
struct util::GraphTraits< Graph >

Graph traits, to allow algorithms to manipulate graphs as adjacency lists. This works with any graph type, and any object that has:

• a size() method returning the number of nodes.
• an operator[] method taking a node index and returning a range of neighbour node indices. One common example is using std::vector<std::vector<int>> to represent adjacency lists.
