Constructor & Destructor Documentation

template<typename User , typename UserCoord = User>

MueLu::MueLuGraphBaseAdapter< User, UserCoord >::~MueLuGraphBaseAdapter ( )

inline

Destructor.

Definition at line 120 of file MueLu_Zoltan2GraphAdapter.hpp.

template<typename User , typename UserCoord >

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

Constructor for graph with no weights or coordinates.

Parameters

ingraph	the Epetra_CrsGraph, Tpetra::CrsGraph or Xpetra::CrsGraph
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.

template<typename User , typename UserCoord >

void MueLu::MueLuGraphBaseAdapter< User, UserCoord >::setWeights	(	const scalar_t *	val,
		int	stride,
		int	idx
	)

Provide a pointer to weights for the primary entity type.

Parameters

val	A pointer to the weights for index `idx`.
stride	A stride for the `val` array. If is `k`, then val[n * k] is the weight for the `n` th entity for index .
idx	A number from 0 to one less than weight idx specified in the constructor.

The order of the weights should match the order that entities appear in the input data structure.

template<typename User , typename UserCoord >

void MueLu::MueLuGraphBaseAdapter< User, UserCoord >::setVertexWeights	(	const scalar_t *	val,
		int	stride,
		int	idx
	)

Provide a pointer to vertex weights.

Parameters

val	A pointer to the weights for index `idx`.
stride	A stride for the `val` array. If is `k`, then val[n * k] is the weight for the `n` th vertex for index .
idx	A number from 0 to one less than number of vertex weights specified in the constructor.

The order of the vertex weights should match the order that vertices appear in the input data structure.

template<typename User , typename UserCoord >

void MueLu::MueLuGraphBaseAdapter< User, UserCoord >::setWeightIsDegree ( int idx )

Specify an index for which the weight should be the degree of the entity.

Parameters

idx	Zoltan2 will use the entity's degree as the entity weight for index `idx`.

Definition at line 385 of file MueLu_Zoltan2GraphAdapter.hpp.

template<typename User , typename UserCoord >

void MueLu::MueLuGraphBaseAdapter< User, UserCoord >::setVertexWeightIsDegree ( int idx )

Specify an index for which the vertex weight should be the degree of the vertex.

Parameters

idx	Zoltan2 will use the vertex's degree as the vertex weight for index `idx`.

Definition at line 400 of file MueLu_Zoltan2GraphAdapter.hpp.

template<typename User , typename UserCoord >

void MueLu::MueLuGraphBaseAdapter< User, UserCoord >::setEdgeWeights	(	const scalar_t *	val,
		int	stride,
		int	idx
	)

Provide a pointer to edge weights.

Parameters

val	A pointer to the weights for index `idx`.
stride	A stride for the `val` array. If is `k`, then val[n * k] is the weight for the `n` th edge for index .
dim	A number from 0 to one less than the number of edge weights specified in the constructor.

The order of the edge weights should follow the order that the the vertices and edges appear in the input data structure.

By vertex:

TheGraph->getRowMap()->getLocalElementList()

Then by vertex neighbor:

TheGraph->getLocalRowView(vertexNum, neighborList);
