Public Member Functions
	SharedOperator (Epetra_Operator &m)
	Constructor.
	~SharedOperator ()
	Destructor.
Epetra_Operator &	getOperator (const Group *newowner)
	Get a non-const reference to the underlying matrix (an epetra operator).
const Epetra_Operator &	getOperator () const
	Return a const reference to the Jacobian.
bool	isOwner (const Group *grp) const
	Return true if grp is the owner of the Jacobian.
bool	setOperator (Epetra_Operator &m)
	RPP: This is a hack that is needed to get MPSalsa running. I will remove this when the Epetra_Vbr is fixed to get a matrix "View" with Aztec2Petra. Essentially, this function allows the underlying Epetra_Operator to be changed. We need this if the operator is destroyed and a new one is created during the NOX::Epetra::Interface::computeJacobian() call.
Protected Attributes
Epetra_Operator *	matrix
	Pointer to Epetra Jacobian matrix.
const Group *	owner
	Pointer to const group that owns Jacobian.

Detailed Description

Shared operator object for NOX::Epetra::Group objects.

Due to the size of certain operators (i.e. the Jacobian and Preconditioning Matrices), we cannot afford to have multiple copies. Instead we implement a shared operator class that that all groups use.
