InstanceState�_T)�boundc � � e Zd ZdZy)�StaleDataErroraa An operation encountered database state that is unaccounted for.
Conditions which cause this to happen include:
* A flush may have attempted to update or delete rows
and an unexpected number of rows were matched during
the UPDATE or DELETE statement. Note that when
version_id_col is used, rows in UPDATE or DELETE statements
are also matched against the current known version
identifier.
* A mapped object with version_id_col was refreshed,
and the version number coming back from the database does
not match that of the object itself.
* A object is detached from its parent object, however
the object was previously attached to a different parent
identity which was garbage collected, and a decision
cannot be made if the new parent was really the most
recent "parent".

d� ddd�� Zdd�Zy) �ObjectDeletedErrora� A refresh operation failed to retrieve the database
row corresponding to an object's known primary key identity.
A refresh operation proceeds when an expired attribute is
accessed on an object, or when :meth:`_query.Query.get` is
used to retrieve an object which is, upon retrieval, detected
as expired. A SELECT is emitted for the target row
based on primary key; if no row is returned, this
exception is raised.
The true meaning of this exception is simply that
no row exists for the primary key identifier associated
with a persistent object. The row may have been
deleted, or in some cases the primary key updated
to a new value, outside of the ORM's management of the target
object.
