Thanks Wouter, this will help a lot.
On a related item. I also found that in the "andromda-cartridge.xml" is where AndroMDA declares the variables that will be available for certain templates, once declared per template I can then reference those variables in my template.

One thing I noticed that in the "andromda-cartridge.xml" when declaring model elements for the template the plural name is used while the classifier
Attribute is singular, see below:
<modelElement variable="applicationUseCases">
<type ame="org.andromda.cartridges.bpm4struts.metafacades.StrutsUseCase">
       <property name="applicationUseCase"/>
   </type>
</modelElement>
Why is that?

That's because outputToSingleFile="true" is set, when this is set to true, all facades of type StrutsUseCase will be aggregated and a collection called "applicationUseCases" will be made available to the template (the file will then only be written once, instead of per model element).

Thanks again, your

Safaa

hi,

there's indeed an API for that, the objects you call from the templates

are called 'facades'

two types of facades exist:

 * uml metafacades, and

 * cartridge facades

the uml facades define an API on top of the element found in the UML model

(the meta-classes)

the cartridge facades extend this API and provide technology specific

features to the templates (for example the ClassifierFacade is extended,

although indirectly, by the SpringEntity facade in the spring cartridge)

the cartridge facades are documented in the Javadoc per cartridge, for

example the ones for bpm4struts are found here:

http://galaxy.andromda.org/docs/andromda-bpm4struts-cartridge/apidocs/index.html

the Javadoc to the generic facades for UML14 can be found here:

http://galaxy.andromda.org/docs/andromda-metafacades-uml14/apidocs/index.html

currently the implementation classes are listed (the ones with the

LogicImpl suffix) and their method start with 'handle' but you'll get the

picture

good luck, make sure to post future questions on our brand-new forum:
