code: def check(self, state, *args, **kwargs):
          
  
          return self._check(state, *args, **kwargs)
docs: Check if this engine can be used for execution on the current state. A callback `check_failure` is called upon
          failed checks. Note that the execution can still fail even if check() returns True.
  
          You should only override this method in a subclass in order to provide the correct method signature and
          docstring. You should override the ``_check`` method to do your actual execution.
  
          :param SimState state: The state with which to execute.
          :param args:                   Positional arguments that will be passed to process().
          :param kwargs:                 Keyword arguments that will be passed to process().
          :return:                       True if the state can be handled by the current engine, False otherwise.
