Obtain global node position and placing node to global position

Hi! I trying to create drag and drop mechanics and stuck with local to global and local-to-global transformations. In docs I found getNodeToWorldTransform and getWorldToNodeTransform methods but when I receive AffineTransform any methods where presented here in runtime only raw data. (Using Cocos 1.6.1) Looking for some guidance how can I actually use that matrices or some other, proper solution.

Thanks in advance!
