# strict-iterators
Warns when `iterator` objects are implicitly cast to `const_iterator`.
This is mostly equivalent to passing -DQT_STRICT_ITERATORS to the compiler.
This prevents detachments but also caches subtle bugs such as:
QHash<int, int> wrong;
if (wrong.find(1) == wrong.cend()) {
qDebug() << "Not found";
} else {
qDebug() << "Found"; // find() detached the container before cend() was called, so it prints "Found"
}
QHash<int, int> right;
if (right.constFind(1) == right.cend()) {
qDebug() << "Not found"; // This is correct now !
} else {
qDebug() << "Found";
}
