Does anybody have any examples of using qualifiers with associations? The Rhapsody documentation that I can find at least mentions the word qualifiers, and even briefly states what it could be used for. I can't find any detailed instructions of how to use it, or examples.

I'm trying to:

1. Create an object
2. Add the object to an association with a key
3. Do stuff
...
...
...
Eventually. Remove the object from the assocation with a key and delete the object.

It looks like qualifiers might assist in this, but I can't find any documentation on it.

Which implementation language do you plan to use? C/C++/Java/Ada?
An example requires using a concrete implementation language...

C++

I know (or think) that I add associations with:

unsigned int key = VALUE;
ClassA *objectA = (ClassA*)(new Class());
addItsOrderedAssociation(key, objectA);


I thought I could access the element by key with:

itsOrderedAssociation[key]->functionCall();

but that doesn't seem to work. I'm resorting to stepping through source code to reverse engineer how to access the element by key.

I found my problem. I read up on OMMap and learned that its implemented as a balanced binary tree. I didn't know that the first (root) node is permanent and cannot be returned. So, I added a dummy node to serve as the root node, and everything works fine.
