Detailed Description

template<class TIndexType = std::size_t>
class Kratos::SparseGraph< TIndexType >

Short class definition.

This class is designed to store a matrix graph, aimed at the fast construction of other sparse matrix formats (particularly CSR) IMPORTANT NOTE: it is BY DESIGN NOT threadsafe! (a graph should be computed in each thread and then merged)
