Hi again,
How should I go to extend the uml14 metafacade? This metafacade does not have a uml diagram. It seems to have been done manually in the file andromda-metafacades.xml. If I am making a new metafacade (lets call it highermetafacade) should I overwrite all of the mappings of the andromda-metafacades.xml.
For example replacing:
<metafacade
metaobjectClass="org.omg.uml.modelmanagement.UmlPackage$Impl"
metafacadeClass="org.andromda.metafacades.uml14.PackageFacadeLogicImpl"/>
by:
<metafacade
metaobjectClass="org.andromda.metafacades.uml14.PackageFacadeLogicImpl"
metafacadeClass="org.andromda.metafacades.highermetafacade.PackageFacadeLogicImpl"/>
Is this what I should do or is there a better/easier solution?
Thanks,
François

Hi Francois,
You should be able to do this, by packageing up your
group of metafacades just like we've done with
andromda-metafacades-uml-*.jar and
andromda-metafacades-uml14-*.jar and placing them on
your classpath with the other default ones.
However there is currently only one set of metafacades belonging to the "default" namespace, and those are the uml and uml14 ones. What you'll need to do with yours then is someone how make them override the "default" namespace, which you should be able to do (I haven't tried)...by placing your new jar of metafacades on the classpath AFTER the normal uml and uml14 metafacades. Does that make sense? Anyway try that out, and if it doesn't work let me know, and I'll fix it so it does work.

Thanks for the answer Wouter.
I would like to adopt the strategy you're defining but for ametametafacade. In other words, I'd like to create a metafacade asuml14. I'm able to do what you're saying with the cartridge but myproblem is that the logic I'm implementing is then not available toother cartridges. I'd like to make myself a new metametafacade (in thelikes of uml14) and would user that metafacade in my cartridges. Mycartridges would then extend these metafacades if they need to.
Concretely:
uml -> uml14 -> HigherMetafacade -> cartridge1
-> cartridge2
-> cartridge3
This way I could add certain methods that are needed by all threecartridges in a metafacade without modifying the uml14 metafacade(which I shouldn't do...right?). Is it possible to define anotherlevel of metafacade...if so how could I do it?
Thanks,

You can pretty much implement any strategy you like,
you will need tomodel your cartridge using UML anyway,
and if you import the existingmodel as for example
used by the UML14 implementation you can extend

how to proceed ? Take a look at the UML model for one

[Andromda-user] Extending the uml14 metafacadeHi,I
would like to build my own metafacade which could be
used by manycartridges. The purpose is to be able to
have my cartridges extendthese metafacades instead of
the uml14 metafacades.For example, lets say I want to
add a method calledgetOneToOneAssociations to the
ClassifierFacade but don't want to modify the uml14 metafacade code (since its not in the
implementation). I don't want to implement this as a cartridge metafacade
either because it will be used by many cartridges and I would like to avoid
duplicating code.How can I do this? Can I extend the
uml14 metafacade and if so how?Otherwise how do I
proceed?Thanks,Francois-------------------------------------------------------This
