It can not make any assumption about your pointer. In theory your 
collection could contain Integers that were simply casted to Pointers. 
In that case a "disposing of the pointer's data" would be fatal!

The methods return Pointers which you can cast to PTLERec. This you can 
then access like a usual object (e.g. dereferencing, etc)
