41 \class QtPrivate::RefCount
42 \inmodule QtCore
43 \internal
44
45 QRefCount implements atomic ref counting for Qt's shared classes. It behaves very similar
46 to QAtomicInt, but ignores negative ref counts.
47
48 This can be used to allow to implement e.g. const read-only QStringData objects. QString::shared_null and
49 the qs(...) macro make use of this feature.
