template<class LocalOrdinal, class GlobalOrdinal, class Node = Tpetra::KokkosClassic::DefaultNode::DefaultNodeType>
class Xpetra::MapUtils< LocalOrdinal, GlobalOrdinal, Node >
Xpetra utility class for common map-related routines.
The routines should be independent from Epetra/Tpetra and be purely implemented in Xpetra.

template<class LocalOrdinal, class GlobalOrdinal, class Node = Tpetra::KokkosClassic::DefaultNode::DefaultNodeType>
Helper function to concatenate several maps.
- Parameters
-
| subMaps | vector of maps which are concatenated |
- Returns
- concatenated map
The routine builds a global map by concatenating all provided maps in the ordering defined by the vector. The GIDs are just appended in the same ordering as in the subMaps. No reordering or sorting is performed. This routine is supposed to generate the full map in an Xpetra::MapExtractor for a block operator. Note, it should not be used for strided maps since the GIDs are not reordered.
Example: subMap[0] = { 0, 1, 3, 4 }; subMap[1] = { 2, 5 }; concatenated map = { 0, 1, 3, 4, 2 ,5 };

template<class LocalOrdinal, class GlobalOrdinal, class Node = Tpetra::KokkosClassic::DefaultNode::DefaultNodeType>
Helper function to shrink the GIDs and generate a standard map whith GIDs starting at 0.
- Parameters
-
| input | Input map (may be overlapping) containing all GIDs. Think of it as a column map. |
| nonOvlInput | Non-overlapping version of "input" map. Think of it is the corresponding domain map associated with the column map "input" |
- Returns
- New map with unique continuous global ids starting with GID 0
This helper routine may be useful for the transformation of MapExtractors in Xpetra-style GID ordering to the Thyra-style ordering.
Example: input = { 10, 15, 26, 37, 48 }; on proc 0 input = { 37, 48, 59, 60, 70 }; on proc 1 nonOvlInput = { 10, 15, 26, 37 }; on proc 0 nonOvlInput = { 48, 59, 60, 70 }: on proc 1 result = { 0, 1, 2, 3, 4 }; on proc 0 result = { 3, 4, 5, 6, 7 }; on proc 1

replace set of global ids by new global ids
- Parameters
-
| input | Overlapping input map. |
| nonOvlInput | Non-overlapping map containing GIDs corresponding to "input". Think of it is the corresponding domain map associated with the column map "input" |
| nonOvlReferenceInput | Non-overlapping reference map containing new GIDs. |
- Returns
- Overlapping map compatible to "input" using the GIDs as defined by "nonOvlReferenceInput"
Example: input = { 0, 1, 2, 3 }; on proc 0 input = { 2, 3, 4, 5 }; on proc 1 nonOvlInput = { 0, 1, 2 }; on proc 0 nonOvlInput = { 3, 4, 5 }: on proc 1 nonOvlReferenceInput = { 33, 44, 55 }; on proc 0 nonOvlReferenceInput = { 101, 102, 103 }; on proc 1 result = { 33, 44, 55, 101 }; on proc 0 result = { 55, 101, 102, 103}; on proc 1
