Deprecated ORM Event Interfaces
===============================
.. module:: sqlalchemy.orm.interfaces
This section describes the class-based ORM event interface which first
existed in SQLAlchemy 0.1, which progressed with more kinds of events up
until SQLAlchemy 0.5. The non-ORM analogue is described at :ref:`dep_interfaces_core_toplevel`.
.. deprecated:: 0.7
As of SQLAlchemy 0.7, the new event system described in
:ref:`event_toplevel` replaces the extension/proxy/listener system, providing
a consistent interface to all events without the need for subclassing.
