[QGIS-Developer] multipartToSingleParts via code

Hi Ben and Nyall,
thanks for your answers.
I resolve the question with the Nyall's processing link and using a part of the code in that link.
It's a little bit difficult for me explain better what's happened because my plugin it's articulated (for my experience), and the multiparttosinglepart is a little part of the code.
You can see the actual version installing it from the official repository, the name is "opeNoise", but in the actual there isn't this problem because I didn't need to use multiparttosinglepart.
Now I'm workinkg to a develop of the plugin.
In any case now it's all ok, even if I didn't use processing algorithm in the code.
Thank you very much!

Oggetto: Re: [QGIS-Developer] multipartToSingleParts via code
Correct me if I'm wrong but my understanding is that you want to be able to call "multiparttosingleparts" in his code the same way you call dissolve.
from qgis.xxx import *
xxx = YYY
Have you tried looking at the API?
I haven't used the qgis processing algorithims in my Python code that way since they already work fine the way they do now. May I know why you'd like such a use case?

Sorry, I don't understand exactly what it is you're wanting to do. Can
