Iterate sub-structures.
These are usable iff solvAttrSubEntry is `true`. Note Unfortunately the underlying libsolv dataiterator as returned by subBegin and subFind loses some context when being created. Thus it's not possible to invoke subBegin and subFind on an iterator that was previously returned by one of those methods. The result will be an `end` iterator. For the same reason it is not possible for an iterator to leave the sub-structure again. * // Lookup all "update:reference" entries for a specific solvable * sat::LookupAttr q( sat::SolvAttr::updateReference, p->satSolvable() ); * for_( res, q.begin(), q.end() ) * { * // List all sub values * for_( sub, res.subBegin(), res.subEnd() ) * { * cout << sub.asString() << endl; * } * * // Directly access c specific value: * sat::LookupAttr::iterator it( res.subFind( sat::SolvAttr::updateReferenceHref ) ); * if ( it != res.subEnd() ) * cout << it.asString() << endl; * } *
