PathNodeIt< Path > Class Template Reference

Detailed Description

template<typename Path>
class lemon::PathNodeIt< Path >

In a sense, the path can be treated as a list of edges. The lemon path type stores just this list. As a consequence it cannot enumerate the nodes in the path and the zero length paths cannot store the node.

This class implements the node iterator of a path structure. To provide this feature, the underlying graph should be given to the constructor of the iterator. #include <lemon/path_utils.h>
