+/*!
+    \class QScriptValueIterator
+
+    \brief The QScriptValueIterator class provides a Java-style iterator for QScriptValue.
+
+    \ingroup script
+
+
+    The QScriptValueIterator constructor takes a QScriptValue 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 QScriptValue:
+
+    \snippet doc/src/snippets/code/src_script_qscriptvalueiterator.cpp 0
+
+    The next() advances the iterator. The name(), value() and flags()
+    functions return the name, value and flags of the last item that was
+    jumped over.
+
+    If you want to remove properties as you iterate over the
+    QScriptValue, use remove(). If you want to modify the value of a
+    property, use setValue().
+
+    Note that QScriptValueIterator only iterates over the QScriptValue'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 doc/src/snippets/code/src_script_qscriptvalueiterator.cpp 1
+
+    Note that QScriptValueIterator will not automatically skip over
+    properties that have the QScriptValue::SkipInEnumeration flag set;
+    that flag only affects iteration in script code.  If you want, you
+    can skip over such properties with code like the following:
+
+    \snippet doc/src/snippets/code/src_script_qscriptvalueiterator.cpp 2
