	Implementation of findCrsIndices. More...
template<class RowPtr , class Indices , class Padding >
void	Tpetra::Details::padCrsArrays (const RowPtr &rowPtrBeg, const RowPtr &rowPtrEnd, Indices &indices, const Padding &padding, const int my_rank, const bool verbose)
	Determine if the row pointers and indices arrays need to be resized to accommodate new entries. If they do need to be resized, resize the indices arrays and shift the existing contents to accommodate new entries. Modify values in the row pointers array to point to the newly shifted locations in the indices arrays. More...
template<class Pointers , class InOutIndices , class InIndices >
size_t	Tpetra::Details::insertCrsIndices (typename Pointers::value_type const row, Pointers const &rowPtrs, InOutIndices &curIndices, size_t &numAssigned, InIndices const &newIndices, std::function< void(const size_t, const size_t, const size_t)> cb=std::function< void(const size_t, const size_t, const size_t)>())
	Insert new indices in to current list of indices. More...
template<class Pointers , class Indices1 , class Indices2 , class Callback >
size_t	Tpetra::Details::findCrsIndices (typename Pointers::value_type const row, Pointers const &rowPtrs, const size_t curNumEntries, Indices1 const &curIndices, Indices2 const &newIndices, Callback &&cb)
	Finds offsets in to current list of indices. More...
