## Class template checked_stepper<DenseOutStepper, Checker, dense_output_stepper_tag>

boost::numeric::odeint::checked_stepper<DenseOutStepper, Checker, dense_output_stepper_tag> — Adapter to combine dense out stepper and checker.

## Synopsis

    // In header: <boost/numeric/odeint/integrate/check_adapter.hpp>

    template<typename DenseOutStepper, typename Checker>
    class checked_stepper<DenseOutStepper, Checker, dense_output_stepper_tag> {
    public:
      // types
      typedef DenseOutStepper          stepper_type;
      typedef Checker                  checker_type;
      typedef stepper_type::state_type state_type;
      typedef stepper_type::value_type value_type;
      typedef stepper_type::deriv_type deriv_type;
      typedef stepper_type::time_type  time_type;

      // construct/copy/destruct
      checked_stepper(stepper_type &, checker_type &);

      // public member functions
      template<typename System> std::pair< time_type, time_type > do_step(System);
      template<typename StateType>
        void initialize(const StateType &, time_type, time_type);
      template<typename StateOut> void calc_state(time_type, StateOut &) const;
      template<typename StateOut>
        void calc_state(time_type, const StateOut &) const;
      const state_type & current_state(void) const;
      time_type current_time(void) const;
      const state_type & previous_state(void) const;
      time_type previous_time(void) const;
      time_type current_time_step(void) const;
    };
