Batch Table Hierarchy (BTH) is a BaseExtension of a Batch Table.

add_class(class_name: str, property_names: list[str]) → HierarchyClass[source]

classmethod from_dict(extension_dict: Dict[str, Any]) → BatchTableHierarchy[source]

Creates an instance of the default extension class BaseExtension. This instance will store all attributes in a single field.

Parameters:: extension_dict – a dict containing all attributes of the extension (keys and values).
Returns:: a BaseExtension instance.

get_instance_parent_indexes(instance: HierarchyInstance) → list[int][source]

Returns:: a dict containing all attributes of the extension (keys and values).
