An implementation of a state object preconditioners.
Teuchos::RCP< Teuchos::ParameterList > unsetParameterList()
Unset the parameter list that was set using setParameterList().
void setParameterList(const Teuchos::RCP< Teuchos::ParameterList > &paramList)
Set parameters from a parameter list and return with default values.
unsigned int getTag() const
Get the tag for this operator.
void setTag(unsigned int tag)
Set the tag for this operator.
Teuchos::RCP< Teuchos::ParameterList > getNonconstParameterList()
Get the parameter list that was set using setParameterList().
virtual void merge(const PreconditionerState &ps, int position=-1)
Merge internal storage of another PreconditionerState object into this one.
