class DescriptorReference(Generic[_DESC]): (source)

View In Hierarchy

a descriptor that refers to a descriptor. used for cases where we need to have an instance variable referring to an object that is itself a descriptor, which typically confuses typing tools as they don't know when they should use ``__get__`` or not when referring to the descriptor assignment as an instance variable. See sqlalchemy.orm.interfaces.PropComparator.prop
