Detailed Description

Concrete LinearOpWithSolveFactoryBase adapter subclass that uses Amesos direct solvers.

This class creates objects of type AmesosLinearOpWithSolve (through the LinearOpWithSolveBase interface) which can then be used to solve for linear systems. The AmesosLinearOpWithSolve objects created and initialized by this object are completely independent from *this. This allows for multiple AmesosLinearOpWithSolve objects to be created and maintained simultaneously and for *this factory object to be destroyed without affecting the created AmesosLinearOpWithSolve objects.

ToDo: Mention parameter list usage.

Development notes: This class has been designed to allow for "smart" EpetraLinearOpBase subclasses that can create an Epetra_Operator view on command where the underlying storage may not be an Epetra object. However, the current implementation of at least some of the Amesos_BaseSolver subclasses do not allow the Epetra_Operator object to change after construction. Therefore, this current flawed implementation requires that every call to the EpetraLinearOpBase::getEpetraOpView() function return the same Epetra_Operator object.

Member Function Documentation

Thyra::AmesosLinearOpWithSolveFactory::STANDARD_COMPOSITION_MEMBERS	(	EpetraOperatorViewExtractorBase	,
		epetraFwdOpViewExtractor
	)

Set the strategy object used to extract an Epetra_Operator view of an input forward operator.

This view will then be dynamically casted to Epetra_RowMatrix before it is used.

The default implementation used is EpetraOperatorViewExtractorBase.
