template<class Scalar> void Thyra::unwrap (  const LinearOpBase< Scalar > &  Op, Scalar *  scalar, ETransp *  transp, const LinearOpBase< Scalar > **  origOp )

Extract the overallScalar, overallTransp and const origOp from a const LinearOpBase object. Parameters: Op  [in] The input, possibly scaled and/or adjoined, linear operator scalar  [out] The overall scaling factor. transp  [out] The overall adjoint (transposition) enum. origOp  [out] The underlying, non-scaled and non-adjoined linear operator. This pointer returns a non-persisting relationship that is to be used and then immediately forgotten. Preconditions: scalar!==NULL transp!==NULL origOp!==NULL Postconditions: *origOp!==NULL The purpose of this function is to strip off the ScaledAdjointLinearOpBase wrapper and get at the underlying linear operator for the purpose of further dynamic casting to some more derived interface. The implementation of this function is not too complicated and is appropriate for study. Definition at line 36 of file Thyra_ScaledAdjointLinearOpBase.hpp.
