Compressed row storage array.
| DataType | The type of stored entries. If a StaticCrsGraph is used as the graph of a sparse matrix, then this is usually an integer type, the type of the column indices in the sparse matrix. |
| Arg1Type | The second template parameter, corresponding either to the Device type (if there are no more template parameters) or to the Layout type (if there is at least one more template parameter). |
| Arg2Type | The third template parameter, which if provided corresponds to the Device type. |
| Arg3Type | The third template parameter, which if provided corresponds to the MemoryTraits. |
| SizeType | The type of row offsets. Usually the default parameter suffices. However, setting a nondefault value is necessary in some cases, for example, if you want to have a sparse matrices with dimensions (and therefore column indices) that fit in int, but want to store more than INT_MAX entries in the sparse matrix. |
A row has a range of entries:
row_map[i0] <= entry < row_map[i0+1] 0 <= i1 < row_map[i0+1] - row_map[i0] entries( entry , i2 , i3 , ... ); entries( row_map[i0] + i1 , i2 , i3 , ... ); Definition at line 260 of file Kokkos_StaticCrsGraph.hpp.

Return a const view of row i of the graph.
If row i does not belong to the graph, return an empty view.
The returned object view implements the following interface:
view.length is the number of entries in the row view.colidx(k) returns a const reference to the column index of the k-th entry in the row k is not a column index; it just counts from 0 to view.length - 1.
Users should not rely on the return type of this method. They should instead assign to 'auto'. That allows compile-time polymorphism for different kinds of sparse matrix formats (e.g., ELLPACK or Jagged Diagonal) that we may wish to support in the future.
