RE: [Andromda-devel] Extending the $transform object

[Anthony M. <to...@am...>]

Rudie,

1) transfromClass vs transformClassname -  I fixed the source to match the
documentation.  It is now 'transformClassname'.

2) more functions in the StringUtilHelper - we can add more functions if
you'd like.  Here is my suggestion:

  instead of implementing all the string functions on the transform class,
make another class and put the helper methods on that class. Implement a
method on your transform that creates your new string helper.  Like so:

  $myStringHelper = $transform.myStringHelper

Then at some point, when you are happy with the set of methods you've put on
the your string helper, send us the code for that class. You can send us the
code by submitting a patch on sourceforge to AndroMDA and sending us an
email saying that you did this.  We can then look at you new string helper
class in isolation from your transform class and decide which methods to add
to the AndroMDA StringUtilHelper.

3)  I wasn't sure exactly what you meant?  So, I'll make a bit of a guess
...

  a) Is the requirement that you'd like to append generated information to
an existing file?

Or

  b) Is it that you'd like to create a file with information about all of
the model elements?

If it is (a) then we currently have no support for doing this, but if you
desparetly needed to do this you could probably get something to work with
some tricks in a new transform class.

If it is (b) then you can do this using existing AndroMDA functionality. In
the set of samples there is the 'model-report' sample.  It is a very simple
example of how to create a file with information about all the model
elements.
