Runtime parameters

RuntimeParameter = Annotated[Union[_T, None], Field(default=None), _RUNTIME_PARAMETER_ANNOTATION] module-attribute

Used to mark the attributes of a Step as a runtime parameter.

RuntimeParametersMixin

Bases: BaseModel

Mixin for classes that have RuntimeParameters attributes.

Attributes:

Name Type Description
_runtime_parameters Dict[str, Any]

A dictionary containing the values of the runtime parameters of the class. This attribute is meant to be used internally and should not be accessed directly.

runtime_parameters_names: RuntimeParametersNames property

Returns a dictionary containing the name of the runtime parameters of the class as keys and whether the parameter is required or not as values.

Returns:

Type Description
RuntimeParametersNames

A dictionary containing the name of the runtime parameters of the class as keys
RuntimeParametersNames

and whether the parameter is required or not as values.

get_runtime_parameters_info()

Gets the information of the runtime parameters of the class such as the name and the description. This function is meant to include the information of the runtime parameters in the serialized data of the class.

Returns:

Type Description
List[Dict[str, Any]]

A list containing the information for each runtime parameter of the class.
