Conditional File Generation [message #57472]

Hi all,
I am using Jet with exemplars to generate code from uml model. I have a
template and I obtain information from Java classes.
Right now I generate always the file, but I only want to generate it for
some classes (i.e.based on the name of the class).
I know how to check the class name in the template, but how can I check
that info in advance and indicate that the new file should only be
generated when the class name has an specific name?
Any help appreciated

Guadalupe:

I am guessing you are using a Rational Software Architect. If so, what
version?

Starting with version 7.5, each generation action has a Condition property
that you can set to an XPath expression (which is evaluated to a boolean
value using the XPath rules).

With earlier RSA versions, you have to resort to more creative techniques:
1) hand modify the main.jet template
2) use techniques similar to those found in this IBM Redbooks publication:

Thanks a lot!
I have version 7.5, I added the condition in the property view and then I
had to "refine" it in the main.jet.
I tried a simple condition and it worked, I will try more complex
conditions in the following days.
Thanks again,
Guadalupe
