Gat a smart pointer to a non-const Epetra_Operator view of a Thyra::LinearOpBase object and how the object is applied to implement the forward linear operator.
| fwdOp | [in] The forward linear operator that the view will be extracted from. This object may be a wrapped scaled/adjoint operator on input. On output this object is "remembered" in the returned RCP for epetraOp. |
| epetraOp | [out] The non-const epetra operator view of *this. |
| epetraOpTransp | [out] Determines if the operator is applied as its transpose or its non-transpose. The Client should use this value and ignore the value in (*epetraOp)->UseTranspose() since it has been shown to be problematic and error prone. |
| epetraOpApplyAs | [out] Determines if the operator should be applied using (*epetraOp)->Apply(...) or using (*epetraOp)->ApplyInverse(...). |
| epetraOpAdjointSupport | [out] Determines if the operator supports transposes or not. |
| epetraOpScalar | [out] The scalar from the wrapped scaled/adjoint linear operator |
Preconditions: epetraOp!=NULL epetraOpOpTransp!=NULL epetraOpApplyAs!=NULL epetraOpAdjointSupport!=NULL
Posconditions: epetraOp->get() != NULL fwdOp.count() is greater on output than on input and hense fwdOp is "remembered"
The object accessed from *epetraOp is only guaranteed to be valid while the returned Teuchos::RCP object exits. This allows for some very specialized implementations where a Epetra_Operator view of *this can be acquired and released according to the lifetime of the returned Teuchos::RCP object.
The Epetra_Operator object may be dynamic casted to more specialized interfaces and therefore modified. Then, when the last RCP object ancestor returned from this function goes away, then *this will be updated to relect the change.

The object accessed from *return is only guaranteed to be valid while the returned Teuchos::RCP object exits. This allows for some very specialized implementations where a Epetra_Operator view of *this can be acquired and released according to the lifetime of the returned Teuchos::RCP object.
Note that if the client tries to constant cast the returned object and modify it that this returned view is not guaranteed to update *this. If the goal is to modify *this then the client should call the non-const version of this function.
