Detailed Description

template<class Scalar, class MV, class OP>
class Belos::Impl::SolverFactoryParent< Scalar, MV, OP >

Specializations of Belos::SolverFactory may inherit from this class to get basic SolverFactory functionality.

This class is not for Belos users. It's really just for Belos developers who want to write a specialization of Belos::SolverFactory. Those developers may make their specialization inherit from this class, in order to get basic Belos::SolverFactory functionality without reimplementing everything.

Template Parameters

Scalar	Same as template parameter 1 of Belos::SolverFactory (which see below).
MV	Same as template parameter 2 of Belos::SolverFactory (which see below).
OP	Same as template parameter 2 of Belos::SolverFactory (which see below).

Member Typedef Documentation

template<class Scalar, class MV, class OP>

typedef ::Belos::SolverManager<Scalar, MV, OP> Belos::Impl::SolverFactoryParent< Scalar, MV, OP >::solver_base_type

The type of the solver returned by create().

This is a specialization of SolverManager for the same scalar, multivector, and operator types as the template parameters of this factory.

typedef CustomSolverFactory<Scalar, MV, OP> Belos::Impl::SolverFactoryParent< Scalar, MV, OP >::custom_solver_factory_type

The type of a solver factory that users may give to addFactory() (which see below)

Member Function Documentation

template<class Scalar , class MV , class OP >

Teuchos::RCP< typename SolverFactoryParent< Scalar, MV, OP >::solver_base_type > Belos::Impl::SolverFactoryParent< Scalar, MV, OP >::getSolver	(	const std::string &	solverName,
		const Teuchos::RCP< Teuchos::ParameterList > &	solverParams
	)

protectedvirtual

Return an instance of the specified solver, or Teuchos::null if this factory does not provide the requested solver.

The preferred way to customize this method is not to inherit from it, but rather to add a custom SolverFactory via addFactory() (which see below). Nevertheless, we leave open the possibility of overriding this method, for example in order to change the order in which users' solver factories are queried.

Note: To implementers: DO NOT THROW if this factory does not recognize and support the input solverName. Instead, just return Teuchos::null. This will make Belos::SolverFactory's implementation cleaner (and is also the reason why we gave this function a different name).

Parameters

solverName	[in] Name of the solver.
solverParams	[in/out] List of parameters with which to configure the solver. If null, we configure the solver with default parameters. If nonnull, the solver may modify the list by filling in missing parameters with default values. You can then inspect the resulting list to learn what parameters the solver accepts.

Some solvers may be accessed by multiple names ("aliases"). Each solver has a canonical name, and zero or more aliases. Using some aliases (such as those that access Flexible GMRES capability in GMRES-type solvers) may make this method set certain parameters in your parameter list.

The input parameter list is passed in as a Teuchos::RCP because the factory passes it to the solver, and Belos solvers want their input parameter list as a Teuchos::RCP<Teuchos::ParameterList>. We allow a null parameter list only for convenience, and will use default parameter values in that case.

Teuchos::RCP< typename SolverFactoryParent< Scalar, MV, OP >::solver_base_type > Belos::Impl::SolverFactoryParent< Scalar, MV, OP >::create	(	const std::string &	solverName,
		const Teuchos::RCP< Teuchos::ParameterList > &	solverParams
	)

virtual

Create, configure, and return the specified solver.

Parameters

solverName	[in] Name of the solver.
solverParams	[in/out] List of parameters with which to configure the solver.

This method differs from getSolver() (see above) only in that it throws an exception if solverName is invalid.

template<class Scalar , class MV , class OP >

int Belos::Impl::SolverFactoryParent< Scalar, MV, OP >::numSupportedSolvers ( ) const

virtual

Number of supported solvers.

This may differ from the number of supported solver names, since we may accept multiple names ("aliases") for some solvers.

Definition at line 492 of file BelosSolverFactory.hpp.

template<class Scalar , class MV , class OP >

Teuchos::Array< std::string > Belos::Impl::SolverFactoryParent< Scalar, MV, OP >::supportedSolverNames ( ) const

virtual

List of supported solver names.

The length of this list may differ from the number of supported solvers, since we may accept multiple names ("aliases") for some solvers.

Definition at line 512 of file BelosSolverFactory.hpp.

template<class Scalar , class MV , class OP >

bool Belos::Impl::SolverFactoryParent< Scalar, MV, OP >::isSupported ( const std::string & solverName ) const

virtual

Whether the given solver name names a supported solver.

Definition at line 550 of file BelosSolverFactory.hpp.

template<class Scalar , class MV , class OP >

void Belos::Impl::SolverFactoryParent< Scalar, MV, OP >::addFactory ( const Teuchos::RCP< custom_solver_factory_type > & factory )

Add a custom solver factory.

Any custom solver factories that you may define will override this factory. "Override" means that if the solverName argument to create() or getSolver() matches any solvers that the custom factories support, then one of the custom factories will create it.

Note: To developers: This is an instance method, but it adds the factory for all current and future instances.

Warning: This method makes no promise of reentrancy or thread safety, with respect to other calls to this or other factories' methods.

A string description of this object.

virtual

Describe this object.

At higher verbosity levels, this method will print out the list of names of supported solvers. You can also get this list directly by using the supportedSolverNames() method.

Reimplemented from Teuchos::Describable.
