If you are interested in the meta type of "thisfolder" in this
case, you can use "REQUEST.PARENTS[0].meta_type".

If you are interested in the one of "myobject", you must find
"myobject". You could use acquisition (not very safe)
or iterate over "PARENTS" (a sequence) or make a catalog search
or ...
