This class describes the interface of extendable undirected bipartite graphs. It extends BaseGraphComponent with functions for adding nodes and edges to the graph. This concept requires AlterableBpGraphComponent.

inline |
This function adds a red new node to the digraph.
|
inline |
This function adds a blue new node to the digraph.
