Hi All,
asking it here, as I couldn't find any clear answer in QHash docs.
Provided I have only one instance of my QHash (so, no detaches are being done),
and the only API of the QHash I'm using is: insert(), remove(), contains() and
operator[], how long I may rely on the reference to value returned by
QHash::operator[]?
E.g.:
QHash<int, MyValue> hash;
hash.insert(1, MyValue(...));
hash.insert(2, MyValue(...));
MyValue &val = hash[1];
hash.remove(2);
// May I rely that now my reference is still valid? Wondering, if any
internal rehash on remove could copy internal data, so that it invalidates the
reference obtained earlier.
Assuming that I keep and use this reference only until I explicitly called
hash.remove() for the key associated with my reference - may I assume that this
reference will be valid?
Best regards
Jarek
