Detailed Description

template<class DiagType, class LocalMapType, class CrsMatrixType>
struct Tpetra::Details::CrsMatrixGetDiagCopyFunctor< DiagType, LocalMapType, CrsMatrixType >

Functor that implements much of the one-argument overload of Tpetra::CrsMatrix::getLocalDiagCopy, for the case where the matrix is fill complete.

Warning

This is an implementation detail of getDiagCopyWithoutOffsets. See that function's documentation first, before considering direct use of this functor.

Template Parameters

DiagType	1-D nonconst Kokkos::View
CrsMatrixType	Specialization of KokkosSparse::CrsMatrix
LocalMapType	Specialization of Tpetra::Details::LocalMap; type of the "local" part of a Tpetra::Map
