## Class failed_step_checker

boost::numeric::odeint::failed_step_checker — A class for performing overflow checks on the failed step count in step size adjustments.

## Synopsis

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

    class failed_step_checker : public boost::numeric::odeint::max_step_checker {
    public:
      // construct/copy/destruct
      failed_step_checker(const int = 500);

      // public member functions
      void operator()(void);
      void reset();
    };

## Description

Used internally within the dense output stepper and integrate routines.

### `failed_step_checker` public construct/copy/destruct

1.     failed_step_checker(const int max_steps = 500);

   Construct the `failed_step_checker`. max_steps is the maximal number of iterations allowed before runtime_error is thrown.

### `failed_step_checker` public member functions

1.     void operator()(void);

   Increases the counter and performs the iteration check.

2.     void reset();

   Resets the `max_step_checker` by setting the internal counter to 0.
