Detailed Description
The Object-oriented API does not have the concept of a GAMS alias. An alias cannot be entered into a GamsDatabase by API methods. Nevertheless, if the GamsDatabase is loaded from a GDX container (e.g. the GamsJob.out_db), the database can contain aliases. Such an alias can be retrieved as a GamsSet and consists of the elements of the aliased set. The method to find out if a GamsSet in a GamsDatabase is indeed an alias is to check if the symbol name is different from the lookup name (i.e. bool isAlias = db["ii"].name != "ii"). This example model goes through the logic of how aliases are handled in the Object-oriented API.
