Inherited from _ClassScanMapperConfig:

Method __init__ Undocumented
Class Variable __slots__ Undocumented
Instance Variable allow_dataclass_fields if true, look for dataclass-processed Field objects on the target class as well as superclasses and extract ORM mapping directives from the "metadata" attribute of each Field.
Instance Variable allow_unmapped_annotations Undocumented
Instance Variable clsdict_view Undocumented
Instance Variable collected_annotations Undocumented
Instance Variable collected_attributes Undocumented
Instance Variable column_copies Undocumented
Instance Variable column_ordering Undocumented
Instance Variable dataclass_setup_arguments if the class has SQLAlchemy native dataclass parameters, where we will turn the class into a dataclass within the declarative mapping process.

Class Method _update_annotations_for_non_mapped_class Undocumented
Method _cls_attr_override_checker Produce a function that checks if a class has overridden an attribute, taking SQLAlchemy-enabled dataclass fields into account.
Method _cls_attr_resolver produce a function to iterate the "attributes" of a class which we want to consider for mapping, adjusting for SQLAlchemy fields embedded in dataclass fields.
