Detailed Description

template<typename User>
class Zoltan2::IdentifierAdapter< User >

IdentifierAdapter defines the interface for identifiers.

Zoltan2 can partition a simple list of weighted identifiers with no geometry or topology provided. IdentifierAdapter defines the interface for adapters of this type.

Adapter objects provide access for Zoltan2 to the user's data. Many built-in adapters are already defined for common data structures, such as Tpetra and Epetra objects and C-language pointers to arrays.

Data types:

scalar_t object weights
lno_t local indices and local counts
gno_t global indices and global counts
node_t is a Kokkos Node type

The Kokkos node type can be safely ignored.

The template parameter User is a user-defined data type which, through a traits mechanism, provides the actual data types with which the Zoltan2 library will be compiled. User may be the actual class or structure used by application to represent a vector, or it may be the helper class BasicUserTypes. See InputTraits for more information.

The scalar_t type, representing use data such as matrix values, is used by Zoltan2 for weights, coordinates, part sizes and quality metrics. Some User types (like Tpetra::CrsMatrix) have an inherent scalar type, and some (like Tpetra::CrsGraph) do not. For such objects, the scalar type is set by Zoltan2 to float. If you wish to change it to double, set the second template parameter to double.
