[TYPO3-mvc] how to get add and remove of an property object

[Domi]

Hello,

I have a domain object and walk through all properties. On MM relations 
there is now a ObjectStorage. Is it possible somehow to get the add - 
remove of this property? I looked into the reflection service but 
coudn't find it.

for example I have countries as property, but the add / remove would be 
addCountry or removeCountry.

Is this possible?

Thanks
Dominic
