Public Member Functions inherited from QIterator< QMetaSequence >
	QIterator (QIterable< QMetaSequence > *iterable, void *iterator)
	Creates an iterator from an iterable and a pointer to a native iterator.
bool	operator== (const QIterator &o) const
	Returns true if other points to the same item as this iterator; otherwise returns false.
bool	operator!= (const QIterator &o) const
	Returns true if other points to a different item than this iterator; otherwise returns false.
QIterator &	operator++ ()
	The prefix {++} operator ({++it}) advances the iterator to the next item in the container and returns an iterator to the new current item.
QIterator &	operator-- ()
	The prefix {–} operator ({–it}) makes the preceding item current and returns an iterator to the new current item.
QIterator &	operator+= (qsizetype j)
	Advances the iterator by j items.
QIterator &	operator-= (qsizetype j)
	Makes the iterator go back by j items.
QIterator	operator+ (qsizetype j) const
	Returns an iterator to the item at j positions forward from this iterator.
QIterator	operator- (qsizetype j) const
	Returns an iterator to the item at j positions backward from this iterator.

\typealias QSequentialIterable::const_iterator

The QSequentialIterable::const_iterator allows iteration over a container in a QVariant.

A QSequentialIterable::const_iterator can only be created by a QSequentialIterable instance, and can be used in a way similar to other stl-style iterators.

        QList<int> intList = {7, 11, 42};
 
        QVariant variant = QVariant::fromValue(intList);
        if (variant.canConvert<QVariantList>()) {
            QSequentialIterable iterable = variant.value<QSequentialIterable>();
            // Can use C++11 range-for:
            for (const QVariant &v : iterable) {
                qDebug() << v;
            }
            // Can use iterators:
            QSequentialIterable::const_iterator it = iterable.begin();
            const QSequentialIterable::const_iterator end = iterable.end();
            for ( ; it != end; ++it) {
                qDebug() << *it;
            }
        }

The QSequentialIterable::iterator allows iteration over a container in a QVariant.

A QSequentialIterable::iterator can only be created by a QSequentialIterable instance, and can be used in a way similar to other stl-style iterators.

Returns the current item, converted to a QVariantRef.
