C++ (Cpp) Ptr::focusIterator Examples

Example #1

File: qaxisstep.cpp Project: Akheon23/chromecast-mirrored-source.vendor

Item::Iterator::Ptr AxisStep::evaluateSequence(const DynamicContext::Ptr &context) const
{
    /* If we don't have a focus, it's either a bug or our parent isn't a Path
     * that have advanced the focus iterator. Hence, attempt to advance the focus on our own. */
    if(!context->contextItem())
        context->focusIterator()->next();

    Q_ASSERT(context->contextItem());

    const QXmlNodeModelIndex::Iterator::Ptr source(context->contextItem().asNode().iterate(m_axis));

    return makeItemMappingIterator<Item>(ConstPtr(this), source, context);
}

Example #2

{
    /* If we don't have a focus, it's either a bug or our parent isn't a Path
     * that have advanced the focus iterator. Hence, attempt to advance the focus on our own. */
    if(!context->contextItem())
        context->focusIterator()->next();

    Q_ASSERT(context->contextItem());

    const QXmlNodeModelIndex::Iterator::Ptr it(context->contextItem().asNode().iterate(m_axis));
    QXmlNodeModelIndex next(it->next());

    while(!next.isNull())
    {
        const Item candidate(mapToItem(next, context));

        if(candidate)
            return candidate;
        else
