String attribute as a connection [message #236007]

Hello everyone,

I would highly appreciate if someone could help me.

Thing I wanted to do is next:

I have 2 abstract classes A and B, and C and D extends them both. Since B
represents constraints, it has String attribute 'requires'.

I would like in the editor to be able to make a connection between two
instances of A's subclasses (C and D, or C and C'...) which would indicate
that C 'requires' D, in other words to fill C's attribute 'requires' with
value 'D', and vice versa, to fill D's attribute with value C.

It is a bit complicated because of this abstract classes, but I need to
have them because of some other dependencies.

My question is: is it possible to do something like this and does anyone
have any suggestion how to do it?

Thanks very much in advance at least for your time reading this.

Regards,
Nikola

Hello Nikola,

Can you use a reference (instead of String "requires" attribute)? And ..
looks like you have to create common superclass for A and B.. (to let B reference
instances of this sulerclass or you can use A as a type of this reference).

Alex, thank you very much for a quick response.

I know that it would be easier if those are references instead of String
attribute, but I didn't want to change the model, because some other stuff
are using it too. But it looks that I will need to do the modifications
after all.

Thanks again.
