Attributes

call(owner: T_Owner, event: EntityDependencyEventType, record: T_Record, *, matched_attributes: frozenset[str] | None = None) → None[source]
Parameters:
Return type:

None

classmethod get_owner_class(cls: type[T], source: type[T] | None = None, **kwargs: Unpack[GetConcreteParentArgumentKwargs]) → type[R]

Resolve and cache the concrete parent argument defined by the descriptor.

The descriptor caches the result per owning class via instance_lru_cache() so repeated introspections remain constant time.

Raises:

GenericsError – If the underlying parent argument cannot be resolved to a concrete type.

Parameters:
Return type:

type[R]

classmethod get_record_class(cls: type[T], source: type[T] | None = None, **kwargs: Unpack[GetConcreteParentArgumentKwargs]) → type[R]

Resolve and cache the concrete parent argument defined by the descriptor.

The descriptor caches the result per owning class via instance_lru_cache() so repeated introspections remain constant time.

Raises:

GenericsError – If the underlying parent argument cannot be resolved to a concrete type.

Parameters:
Return type:

type[R]

match_attributes(owner: T_Owner, record: T_Record, journal: Journal) → frozenset[str] | None[source]
Parameters:
