[henshin-dev] ConditionalUnit example

[Sébastien Pasero <sebastien.pasero@xxxxxx>]

Hi,

I would like to have some examples using a ConditionalUnit during a 
Henshin transformation.
I don't understand how the "if" condition works :
 - Shall the rule return a boolean parameter ? How ?
 - Shall the rule return a parameter, and if it's null or empty, the 
condition is false ?
 - Anything else ?

Here is what I'm doing :
My source ecore model contains a class "Platform", with an attribute 
named "wordSize", which can have following values : 16 or 32.
I would like to transform this to :
 - a class "MyNewPlatform" with its attribute "wordSize" set to _16 
(it's an enumeration value) if Platform.wordSize = 16
 - a class "MyNewPlatform" with its attribute "wordSize" set to _32 
(it's an enumeration value) if Platform.wordSize = 32

Could you help me with this ?

Regards,
Sebastien
