+    \class QJSValueIterator
+
+    \brief The QJSValueIterator class provides a Java-style iterator for QJSValue.
+
+    \ingroup qtjavascript
+    \inmodule QtQml
+
+
+    The QJSValueIterator constructor takes a QJSValue as
+    argument.  After construction, the iterator is located at the very
+    beginning of the sequence of properties. Here's how to iterate over
+    all the properties of a QJSValue:
+
+    \snippet code/src_script_qjsvalueiterator.cpp 0
+
+    The next() advances the iterator. The name() and value()
+    functions return the name and value of the last item that was
+    jumped over.
+
+    Note that QJSValueIterator only iterates over the QJSValue's
+    own properties; i.e. it does not follow the prototype chain. You can
+    use a loop like this to follow the prototype chain:
+
+    \snippet code/src_script_qjsvalueiterator.cpp 1
+
+    \sa QJSValue::property()

+/*!
+    Constructs an iterator for traversing \a object. The iterator is
+    set to be at the front of the sequence of properties (before the
+    first property).
