| # Parameter description classes |
| # |
| # The _params dictionary in each class maps parameter names to either |
| # a Param or a VectorParam object. These objects contain the |
| # parameter description string, the parameter type, and the default |
| # value (if any). The convert() method on these objects is used to |
| # force whatever value is assigned to the parameter to the appropriate |
| # type. |
| # |
| # Note that the default values are loaded into the class's attribute |
| # space when the parameter dictionary is initialized (in |
| # MetaSimObject._new_param()); after that point they aren't used. |
