classes in packages. [message #470242]

Hi,

Whenever I start UML graphical editor, my eclipse runs out of memory after a
few minutes. Any thoughts on recommended memory size?
For now, I am using the EMF editor and opening the file in the graphical
editor to take a printout in the end.

I created a few packages and relationships between classes of these
packages.
When I view the same in graphical editor, i am just getting the list view of
classes in a package box. Neither class attributes nor associations are
visible any more.
Is there a way to visualize the same?

Thanks
Pradeep

Hello Pradeep,

Check your log file. Usually there are not much information provided about
the OutOfMemoryError,
but please check whether it is about PermGen space or not.

If yes, than increase it via command line parameters to eclipse launcher.
Here, at Windows, I am using following command to run Eclipse

start eclipse.exe -vmargs -Xmx512m -Xms256m -XX:PermSize=64M -XX:MaxPermSize=128M

and it works well enough.

Regarding the second question, I am not sure I understand you.
If possible please provide me with model / diagram files, probably it will
help me to understand and fix the problem.

Regards,
Michael

Please find the example attached.(Both uml file and the screenshot of
generated diagram).

Brief description:

1) I took the same PurchaseOrder uml model.
2) Created two packages, customer, company
3) Moved Customer, Address, etc. to customer package.
4) Order, Supplier etc. to company package.
5) Reinitialized the diagram.
6) If you see now, all the links are no more visible.

Also please find the attached diagram that I have drawn using GMF for some
other project.
I expect some thing like that.

Hello Pradeep,

Its expected behavior, we are not displaying links to/from elements inside
the list compartments (that are, in fact, pure labels).
(BTW, your other sample shows the links to inner nodes that have its own
complete graphical representation, figures, etc).

May be I am wrong, but in the whole UML spec (06-04-02) I did not saw any
samples of such links.
Also none of Borland/Together UML products for last 7 years showed such links.
As far as I can remember, IBM / Rational products also followed this way.
So, may be wrong, but we are in good company now :).

Please submit feature request, however, if you think this should be done
different way.

Regards,
Michael

Hi Michael,

I think there should be a way to visualize my classes and associations in
the diagram.
Do you think they should be given a listbox treatment and with a simple name
just because they are inside a package?

Here is how a diagram looks like in Rational software modeler. While I am
not a big fan of those package links, atleast my classes are visible.
