What about real polymorphism ?? [message #41991]

Hi group,

my problem is with IDL's polymorphism, i think it's a half-polymorphims
instead real polymorphism.

Supose we have a class Person and two subclasses Man and Woman. Class
Person has a class called GetInfo() that is overriden in both Man and
Woman. The question is:

How can i create an array of Person's (that is Man or Woman objects) and
call the method GetInfo() in the way that depends on the subtype of
every object it invoques the Man GetInfo() or the Woman GetInfo()??

One possible solution is using OBJ_ISA funtion for every object in the
array but i want to know if it is possible only with polymorfism in IDL
like in Java or other OO languages.

Thanks.
