JSONCodec

class gufe.custom_json.JSONCodec(cls: type | None, to_dict: Callable[[Any], dict], from_dict: Callable[[dict], Any], is_my_obj: Callable[[Any], bool] | None = None, is_my_dict=None)

Custom JSON encoding and decoding for non-default types.

Parameters:

• cls (class) – Class for this codec. Assumes that all subclasses should be treated the same way. Can be None if is_my_obj and is_my_dict are given.

• to_dict (Callable) – method that converts the object to a dictionary

• from_dict (Callable) – method that restores the object based on the dictionary made by to_dict

• is_my_obj (Optional[Callable]) – Method to determine whether the input object should be treated by this encoder. Default behavior is to use isinstance(cls), and to create a dict that also includes the class name and the module of the object.

• is_my_dict (Optional[Callable]) – Method to determine whether the input dictionary should be treated by this decoder. Default behavior assumes usage of the default is_my_obj.
