Get scaled size , anchor in points

cocos2d-x C++
#1

Why there isn’t any method returning scaled size or anchor point? I use something like this:

static float getScaledWidth(CCNode* pNode)
{
    return pNode->getContentSize().width * pNode->getScaleY();
}

static float getScaledHeight(CCNode* pNode)
{
    return pNode->getContentSize().height * pNode->getScaleY();
}

static CCSize getScaledSize(CCNode* pNode)
{
    return CCSize(getScaledWidth(pNode),getScaledHeight(pNode));
}
