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.
