transformation template aritmetic operations

[shadowmulder]

Hi
I am transforming a physical model into a logical.

for one string manipulation I need a arithmetic operation (MINUS):

Code: [Select]

//e.g. find first occurence of _
$NameFirstUnderline = %FIND(attName,"_")%
//remove prefix
$Prefix = %LEFT(className,$NameFirstUnderline-1)%
how I decrease the index?

Long time ago I used that so my knowledge may be outdated. The transformation is rather limited and IIRC it is not possible to make math. But you can call a user-defined add-in function to do that for you.

Interesting, can you give me a little more info about that:
A link or a menu entry where I can find that

in what language this functions are written?

Hi,

Look here http://www.sparxsystems.com/enterprise_architect_user_guide/9.3/standard_uml_models/functionmacros.html for the EXEC_ADD_IN() macro.
BTW, for an actual project of mine I decided to generate the complete transformation intermediary language using AddIn function(s), because the transformation templates don't fit very well for my purposes.

You can write AddIns in any language that supports creating COM interop enabled DLLs. I personally prefer C# for this ...

Welcome to the club :-) I did exactly the same some years ago and would do that again next time it's needed.

Hello all,


Maybe the following will solve the question.

$result = %MATH_ADD($NameFirstUnderline,"-1")%
$Prefix = %LEFT(className,$result)%

(It may be limited to some upper editions.)

Hope this helps,

thx to you all, this helped!

the possibility to add some helper is good for deeper things

the MATH_ADD is really helpfull, why is this not in official reference? or why it cant be found over STRG+SPACE ?

Sometimes they add more features than the documentation guys can handle (which is not necessarily an advantage). However, EA's documentation is outstanding compared to most other SW I know. Probably Roy will read this post too and update the documentation.

I like EA, because it is a quick and stable SW, but to be honest, I know SW which has definitely better documentation (updated, structured and more understandable). What I also miss is more docu from outside (blogs, tutorials). The templating language is a blind flight, I use it only because it brings a big advantage.
But the forum gave me a quick answear   thx
