Detailed Description

template<class LocalOrdinal = DefaultLocalOrdinal, class GlobalOrdinal = DefaultGlobalOrdinal, class Node = DefaultNode>
class MueLu::LWGraph< LocalOrdinal, GlobalOrdinal, Node >

Lightweight MueLu representation of a compressed row storage graph.

This class is lightweight in the sense that it holds to local graph information. These were built without using fillComplete. TODO handle systems
