=================================
:mod:`zope.event` Documentation
=================================
This package provides a simple event system on which
application-specific event systems can be built. For example, a
type-based event dispatching system that builds on `zope.interface
<https://zopeinterface.readthedocs.io/en/latest/>`_ can be found in
`zope.component <https://zopecomponent.readthedocs.io/en/latest>`_. A
simpler system is distributed with this package and is described in :doc:`classhandler`.
Application code can generate events without being concerned about the
event-processing frameworks that might handle the events.
Events are objects that represent something happening in a system.
They are used to extend processing by providing processing plug
points.
