Detailed Description

template<class LocalOrdinal = int, class GlobalOrdinal = LocalOrdinal, class Node = Kokkos::DefaultNode::DefaultNodeType>
class Tpetra::RowGraph< LocalOrdinal, GlobalOrdinal, Node >

A pure virtual interface for row-partitioned graphs.

This class is templated on LocalOrdinal, GlobalOrdinal and Node. The LocalOrdinal type, if omitted, defaults to int. The GlobalOrdinal type defaults to the LocalOrdinal type. The Node type defaults to the default node in Kokkos.
