Detailed Description

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

Provides access for Zoltan2 to Tpetra::RowGraph 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.

The template parameter is the user's input object:

Tpetra::CrsGraph
Tpetra::RowGraph
Epetra_CrsGraph

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.

Constructor & Destructor Documentation

template<typename User , typename UserCoord >

Zoltan2::TpetraRowGraphAdapter< User, UserCoord >::TpetraRowGraphAdapter	(	const RCP< const User > &	ingraph,
		int	nVtxWeights = `0`,
		int	nEdgeWeights = `0`
	)

Constructor for graph with no weights or coordinates.

Parameters

ingraph	the Tpetra::RowGraph
numVtxWeights	the number of weights per vertex (default = 0)
numEdgeWeights	the 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.

weights	is the list of weights of the given index for the edges returned in getEdgeView().
stride	The k'th weight is located at weights[stride*k]
idx	ranges from zero to one less than getNumWeightsPerEdge().
