Hi
As Yi said, Ryu dynamically generates event classes, including
EventOFPSwitchFeatures class.
You can see the detailed description in the Ryu documentation:
http://ryu.readthedocs.io/en/latest/ryu_app_api.html#event-classes
Thanks,
Fujimoto

Hi
Ryu generate events at runtime by using exists OpenFlow definition
(ryu/ofproto/....)
The reason I think is they don't need to create new file when they add
new OpenFlow definition.
You can find here:

Greeting!
It’s confused me that when I read the simple_switch_13.py in app,
the file mentioned about off_event.EventOFPSwitchFeatures,but I
don’t find the EventOFPSwitchFeatures class in ofp_event.py in
controller.And I want to know how could simple_switch_13.py run
without defining EventOFPSwitchFeatures class?
ps:the ofp_event.EventOFPPacketIn event is not defining in this
file too.
Thanks!
