[Trilinos-Users] AztecOO and ~OperatorData()

[Simone Deparis]

Hi,

I have the following issue/understanding:

I have a preconditioner P of type Prec derived from Epetra_Operator:

Prec P;

I set this as preconditioner to Aztec00:

{
  AztecOO Solver(Problem); // Problem is of class Epetra_LinearProblem
  Solver.SetPrecOperator(&P);
  M_Solver->Iterate(numiter, tol);
}

Now the instance Solver of Aztec00 has been destroyed (since outside the
brackets).
If I look through Aztec00.cpp, the destruction of Solver has involved
the distruction of my preconditioner P
( through  AztecOO::DeleteMemory() and AztecOO::~AztecOO(void) ).

Do I understand well what's going on? If I am right, is this the
behavior that we wish?
I don't! I would prefer that I decide when to destroy my preconditioner.
 Is there a reason for this?

Thank you

Simone
