Detailed Description

template<typename _Graph, typename _Traits = DefaultReaderTraits>
class lemon::EdgeMapReader< _Graph, _Traits >

The lemon format can store maps in the edgeset sections. This class let you make distinict section to store maps. The main purpose of this class is a logical separation of some maps. The other useful application could be to store paths in edge maps.

The first line of the section contains the names of the maps separated with white spaces. Each next line describes an item in the itemset, and contains in the first column the label of the item and then the mapped values for each map. #include <lemon/lemon_reader.h>
