Detailed Description

template<typename User, typename UserCoord = User>
class Zoltan2::TpetraCrsGraphAdapter< User, UserCoord >

Provides access for Zoltan2 to Tpetra::CrsGraph data.

Todo:

test for memory alloc failure when we resize a vector

we assume FillComplete has been called. Should we support objects that are not FillCompleted.

Constructor & Destructor Documentation

template<typename User , typename UserCoord >
Zoltan2::TpetraCrsGraphAdapter< User, UserCoord >::TpetraCrsGraphAdapter ( const RCP< const User > &  graph,
int  nVtxWeights = 0,
int  nEdgeWeights = 0 
)

Constructor for graph with no weights or coordinates.

Parameters
ingraphthe Tpetra::CrsGraph
numVtxWeightsthe number of weights per vertex (default = 0)
numEdgeWeightsthe number of weights per edge (default = 0)

Most adapters do not have RCPs in their interface. This one does because the user is obviously a Trilinos user.
