android - Avoid deleting children objects - Realm -

-

i have following scenario:

one dose has 1 or more nutrients , when dose deleted nutrients stay in database. there annotation allows that?

thank in advance!

if delete dose object, links invalidated, nutrient classes belong stay in database when call dose.deletefromrealm().

so that's default use-case.
