Hi,
I am trying to run following query on OCL Interpreter Console basically it tries to calculate Depth of Inheritance tree. From the theoritical part it looks fine, I need to define this query for my work, but it is hard to redefine it on UML metamodel , and on M2 layer. I do not find iterate(), isRoot() in the current specifications. I will be very gratefull if some body share his thougts to run it on eclipse OCL interpreter console or any other method to find DIT on OCL interpreter.

The source of this query is the following paper:
source: http://ctp.di.fct.unl.pt/QUASAR/Resources/Papers/2002/QUAOOS E2002FinalAline.pdf

Class::DIT():Integer 
post: result = (if self.IsRoot() then 
                   0 
    else 
       1 + self.Parents()->iterate(elem:Class; acc:Integer=0 | 
if elem.DIT() > acc then 
elem.DIT() 
else 
acc 
endif) 
    endif)


Thanks in advance,
arise
