OpenDaylight: How to get notified when a switch connects

Question

I am working with opendaylight Carbon. I want to write a DataTreeChangeListener which gets notified when a switch connects. I tried modeling this on the LearningSwitch example of the OpenFlow plugin but I do not see any notification when mininet connects to openflow.

Any pointers on how to do this would be greatly appreciated.

Thanks,

Is is OK for you if you get notified when a link appears (and therefore, get the source and destination switches from the link)? — Marievi, Sep 07 '17 at 05:49
I found a good pointer on how to do this by looking at the learningswitch example. However, I now find I get multiple notifications. — LostInTheFrequencyDomain, Sep 07 '17 at 17:07
Could you explain a bit more what you mean by multiple notifications? Or show some code? — Marievi, Sep 07 '17 at 18:20

Have look at this, we use this class to add default flows when DPN gets connected
