virtual LinearOp Teko::BlockPreconditionerFactory::buildPreconditionerOperator	(	BlockedLinearOp &	blo,
		BlockPreconditionerState &	state
	)		const `[pure virtual]`

Function that is called to build the preconditioner for the linear operator that is passed in.

This function builds a preconditioner based on the passed in BlockedLinearOp.

Parameters:

[in]	blo	Source linear operator that is to be preconditioned.
[in]	state	An object associated with this operator to store the preconditioner state.

Returns:: The preconditioner as a linear operator (i.e. to perform a matrix-vector operation simply call "apply").

Implemented in Teko::LU2x2PreconditionerFactory, Teko::NS::ModALPreconditionerFactory, Teko::GaussSeidelPreconditionerFactory, Teko::MultPreconditionerFactory, Teko::JacobiPreconditionerFactory, Teko::NS::SIMPLEPreconditionerFactory, and Teko::AddPreconditionerFactory.

virtual RCP<PreconditionerState> Teko::BlockPreconditionerFactory::buildPreconditionerState ( ) const [inline, virtual]

Function that permits the construction of an arbitrary BlockPreconditionerState object.

Function that permits the construction of an arbitrary BlockPreconditionerState object. If the basic state object, which takes a parameter list, is sufficient the default behavior does precisely what is needed. Otherwise, an author of a PreconditionerFactory would need to reimplement this method to return a new state object.

Returns:: A state object associated with this factory.

Reimplemented from Teko::PreconditionerFactory.

Reimplemented in Teko::NS::ModALPreconditionerFactory, Teko::MultPreconditionerFactory, and Teko::AddPreconditionerFactory.

RCP<BlockPreconditionerState> Teko::BlockPreconditionerFactory::buildBlockPreconditionerState ( ) const [inline]

Function that constructs a BlockPreconditionerState object.

This function is simply included for convenience. Its implementation just call "buildPreconditionerState" and returns a dynamically casted BlockPreconditionState poniter.

LinearOp Teko::BlockPreconditionerFactory::buildPreconditionerOperator	(	LinearOp &	lo,
		PreconditionerState &	state
	)		const `[virtual]`

Function that is called to build the preconditioner for the linear operator that is passed in.

This function builds a preconditioner based on the passed in LinearOp.

Parameters:

[in]	lo	Source linear operator that is to be preconditioned.
[in]	state	An object associated with this operator to store the preconditioner state.

Returns:: The preconditioner as a linear operator (i.e. to perform a matrix-vector operation simply call "apply").

Implements Teko::PreconditionerFactory.

bool Teko::BlockPreconditionerFactory::isCompatible ( const Thyra::LinearOpSourceBase< double > & fwdOpSrc ) const

is this operator compatiable with the preconditioner factory?

Reimplemented from Teko::PreconditionerFactory.
