Detailed Description

template<typename BGR>
class lemon::BpGraphReader< BGR >

This utility reads an LGF file.

It can be used almost the same way as GraphReader, but it reads the red and blue nodes from separate sections, and these sections can contain different set of maps.

The red and blue node maps are read from the corresponding sections. If a map is defined with the same name in both of these sections, then it can be read as a node map.

BpGraphReader& skipNodes ( )

inline

Omit the reading of the node section. This implies that each node map reading rule will be abandoned, and the nodes of the graph will not be constructed, which usually cause that the edge set could not be read due to lack of node name could not be read due to lack of node name resolving. Therefore skipEdges() function should also be used, or useNodes() should be used to specify the label of the nodes.

BpGraphReader& skipEdges ( )

inline

Omit the reading of the edge section. This implies that each edge map reading rule will be abandoned, and the edges of the graph will not be constructed.

void run ( )

inline

This function starts the batch processing
