Detailed Description

template<class Scalar>
class TSFExtended::VectorTypeExtensions< Scalar >

VectorTypeExtensions provides extensions to the Thyra::VectorSpaceFactoryBase object, appropriate to the interface with applications codes.

Thyra::VectorSpaceFactoryBase has a method to create a small serial vector space for use in multivector operators, however, that is insufficient for the needs of applications.

Notes for subclass developers

Subclasses should also derive from some subclass of Thyra::VectorSpaceFactoryBase in order to use the createReplicatedSpace() method.

Because applications may use the clean syntax

 VectorType vt = new MyVectorType();

subclasses should also derive from Handleable<VectorTypeBase<Scalar> and implement the getRcp() method.

Subclasses might optionally implement the Printable and Describable interfaces

Member Function Documentation

template<class Scalar >

VectorSpace< Scalar > TSFExtended::VectorTypeExtensions< Scalar >::createEvenlyPartitionedSpace	(	const MPIComm &	comm,
		int	nLocal
	)		const [inline, virtual]

Default implementation creates a vector space having nLocal elements on each processor.

Serial types should override this to produce a replicated space.

Reimplemented in TSFExtended::SerialVectorType.

template<class Scalar>

virtual RCP<GhostImporter<Scalar> > TSFExtended::VectorTypeExtensions< Scalar >::createGhostImporter	(	const VectorSpace< Scalar > &	space,
		int	nGhost,
		const int *	ghostIndices
	)		const [pure virtual]

Create an importer for accessing ghost elements.

Parameters:

space	the distributed vector space on which ghost elements are to be shared
nGhost	number of ghost elements needed by this processor
ghostIndices	read-only C array of off-processor indices needed by this processor.

Returns:

A RCP to a GhostImporter object.

Implemented in TSFExtended::EpetraVectorType, and TSFExtended::SerialVectorType.

template<class Scalar>

virtual RCP<MatrixFactory<Scalar> > TSFExtended::VectorTypeExtensions< Scalar >::createMatrixFactory	(	const VectorSpace< Scalar > &	domain,
		const VectorSpace< Scalar > &	range
	)		const [pure virtual]

Create a matrix factory of type compatible with this vector type, sized according to the given domain and range spaces.

Implemented in TSFExtended::EpetraVectorType, and TSFExtended::SerialVectorType.

template<class Scalar>

virtual RCP<const Thyra::VectorSpaceBase<Scalar> > TSFExtended::VectorTypeExtensions< Scalar >::createSpace	(	int	dimension,
		int	nLocal,
		const int *	locallyOwnedIndices,
		const MPIComm &	comm
	)		const [pure virtual]

create a distributed vector space.

Parameters:

dimension	the dimension of the space
nLocal	number of indices owned by the local processor
locallyOwnedIndices	array of indices owned by this processor

Implemented in TSFExtended::EpetraVectorType, and TSFExtended::SerialVectorType.
