Base interface for objects that can return a linear operator.
Simple interface class to access a precreated preconditioner as one or more linear operators objects ...
Factory interface for creating preconditioner objects from LinearOpBase objects.
virtual void uninitializePrec(PreconditionerBase< Scalar > *prec, RCP< const LinearOpSourceBase< Scalar > > *fwdOpSrc=NULL, ESupportSolveUse *supportSolveUse=NULL) const =0
Uninitialize a LinearOpBase preconditioner object and return its remembered forward linear operator.
virtual bool applySupportsConj(EConj conj) const
Return if precOp->apply() supports the argument conj.
virtual bool isCompatible(const LinearOpSourceBase< Scalar > &fwdOpSrc) const =0
Check that a LinearOpBase object is compatible with *this factory object.

Create and initialize a preconditioner from a forward linear operator.
virtual void initializePrec(const RCP< const LinearOpSourceBase< Scalar > > &fwdOpSrc, PreconditionerBase< Scalar > *precOp, const ESupportSolveUse supportSolveUse=SUPPORT_SOLVE_UNSPECIFIED) const =0
Initialize a pre-created LinearOpBase preconditioner object given a "compatible" LinearOpBase object.
virtual RCP< PreconditionerBase< Scalar > > createPrec() const =0
Create an (uninitialized) LinearOpBase object to be initialized as the preconditioner later in this->...
virtual bool applyTransposeSupportsConj(EConj conj) const
Return if precOp->solveTranspose() supports the argument conj.
