Python plug-in -- UML: how to access the association end?

[georges Louis <georges louis univ-lr fr>]

Hi,

Does anyone know how to access, from a Python plug-in, the "association 
end" in a UML diagram  ?
More precisely, I would need the multiplicity and the role name.

(I see the ends in the .dia file, I see them at various places in the C 
code, but I don't find them in the Python objects. The example scripts I 
have seen do not use them either.)

Thanks

Georges Louis
