void Build(Level ¤tLevel) const
Build an object with this factory.
void DeclareInput(Level ¤tLevel) const
Specifies the data that this class needs, and the factories that generate that data.
T & Get(const std::string &ename, const FactoryBase *factory=NoFactory::get())
Get data without decrementing associated storage counter (i.e., read-only access). Usage: Level->Get< RCP<Matrix> >("A", factory) if factory == NULL => use default factory.
RCP< ParameterList > defaultZoltan2Params
Teuchos::FancyOStream & GetOStream(MsgType type, int thisProcRankOnly=0) const
Get an output stream for outputting the input message type.
T & get(const std::string &name, T def_value)
