Detailed Description

A single Epetra wrapper for all operators constructed from an inverse operator.

This class uses the Teko inverse factories to build an Epetra_Operator that behaves like the inverse operatotr. This is done by using the InverseFactory, and letting it build whatever operator is neccessary. Thus the Epetra "layer" is just a single class that handles any generic InverseFactory.

void Teko::TpetraHelpers::InverseFactoryOperator::initInverse ( bool clearOld = false )

virtual

Build the underlying data structure for the inverse operator.

Build the underlying data structure for the inverse operator. This permits the manipulation of the state object for an inverse operator.

Parameters

[in] clearOld If true any previously constructed operator will be wiped out and a new one created. If false, anoperator will be created only if the current one is empty (i.e. initPreconditioner had not been called).

void Teko::TpetraHelpers::InverseFactoryOperator::buildInverseOperator	(	const Teuchos::RCP< const Tpetra::Operator< ST, LO, GO, NT > > &	A,
		bool	clear = `true`
	)

virtual

Build this inverse operator from an Epetra_Operator passed in to this object.

Build this inverse operator from an Tpetra::Operator<ST,LO,GO,NT> passed in to this object.

Build this inverse opeerator from an Epetra_Operator passed in to this object. If this Epetra_Operator is an EpetraOperatorWrapper object then the block Thyra components are extracted.

Parameters

[in]	A	The Epetra source operator.
[in]	clear	If true, than any previous state saved by the operator is discarded.

Build this inverse opeerator from an Tpetra::Operator<ST,LO,GO,NT> passed in to this object. If this Tpetra::Operator<ST,LO,GO,NT> is an EpetraOperatorWrapper object then the block Thyra components are extracted.

Parameters

[in]	A	The Epetra source operator.
[in]	clear	If true, than any previous state saved by the operator is discarded.

		bool	clear = `true`
	)

virtual

Build this inverse operator from an Epetra_Operator passed in to this object.

Build this inverse opeerator from an Epetra_Operator passed in to this object. If this Epetra_Operator is an EpetraOperatorWrapper object then the block Thyra components are extracted.

Parameters

[in]	A	The Epetra source operator.
[in]	clear	If true, than any previous state saved by the operator is discarded.

void Teko::TpetraHelpers::InverseFactoryOperator::rebuildInverseOperator ( const Teuchos::RCP< const Tpetra::Operator< ST, LO, GO, NT > > & A )

virtual

Rebuild this inverse from an Epetra_Operator passed in this to object.

Rebuild this inverse from an Tpetra::Operator<ST,LO,GO,NT> passed in this to object.

Rebuild this inverse from an Epetra_Operator passed in this to object. If buildInverseOperator has not been called the inverse operator will be built instead. Otherwise efforts are taken to only rebuild what is neccessary. Also, that this Epetra_Operator may be an EpetraOperatorWrapper object, so the block Thyra components can be extracted.

Parameters

[in] A The Epetra source operator. (Should be a EpetraOperatorWrapper!)

Rebuild this inverse from an Tpetra::Operator<ST,LO,GO,NT> passed in this to object. If buildInverseOperator has not been called the inverse operator will be built instead. Otherwise efforts are taken to only rebuild what is neccessary. Also, that this Tpetra::Operator<ST,LO,GO,NT> may be an EpetraOperatorWrapper object, so the block Thyra components can be extracted.

Parameters

[in] A The Epetra source operator. (Should be a EpetraOperatorWrapper!)
