- \class QJSValueIterator
-
- \brief The QJSValueIterator class provides a Java-style iterator for QJSValue.
-
- \ingroup qtjavascript
-
-
- 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 doc/src/snippets/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 doc/src/snippets/code/src_script_qjsvalueiterator.cpp 1
-
- Note that QJSValueIterator will not automatically skip over
- properties that have the QJSValue::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_qjsvalueiterator.cpp 2
-
- \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).
-*/
-QJSValueIterator::QJSValueIterator(const QJSValue& object)
- : d_ptr(new QJSValueIteratorPrivate(QJSValuePrivate::get(object)))
-{}
-
-/*!
- Destroys the iterator.
-*/
-QJSValueIterator::~QJSValueIterator()
-{}
-
-/*!
- Returns true if there is at least one item ahead of the iterator
- (i.e. the iterator is \e not at the back of the property sequence);
- otherwise returns false.
-
- \sa next()
-*/
-bool QJSValueIterator::hasNext() const
-{
- Q_D(const QJSValueIterator);
- QScriptIsolate api(d->engine());
- return d->hasNext();
