C++ (Cpp) isExtensible Examples

Example #1

File: Structure.cpp Project: dog-god/iptv

// In future we may want to cache this property.
bool Structure::isSealed(JSGlobalData& globalData)
{
    if (isExtensible())
        return false;

    materializePropertyMapIfNecessary(globalData);
    if (!m_propertyTable)
        return true;

    PropertyTable::iterator end = m_propertyTable->end();
    for (PropertyTable::iterator iter = m_propertyTable->begin(); iter != end; ++iter) {
        if ((iter->attributes & DontDelete) != DontDelete)
            return false;
    }
    return true;
}

Example #2

File: Structure.cpp Project: jbat100/webkit

// In future we may want to cache this property.
bool Structure::isFrozen(JSGlobalData& globalData)
{
    if (isExtensible())
        return false;

    materializePropertyMapIfNecessary(globalData);
    if (!propertyTable())
        return true;

    PropertyTable::iterator end = propertyTable()->end();
    for (PropertyTable::iterator iter = propertyTable()->begin(); iter != end; ++iter) {
        if (!(iter->attributes & DontDelete))
            return false;
        if (!(iter->attributes & (ReadOnly | Accessor)))
            return false;
    }
    return true;
