Creating new connector in Transformation Template

[Kezia]

Hi,

I have difficulty in creating a new connector in XSD Transformation template. This is the scenario :
I want to create a new class based on an existing class and add a new connector which its type is Dependency and its stereotype is "derivedFrom". I have tried sample code from EA help :

Code: [Select]


Dependency
{
%TRANSFORM_REFERENCE("SourceDependency",classGUID)%
stereotype="derivedFrom"
Source
{
  %TRANSFORM_REFERENCE("Class",classGUID)%
}
Target
{
  GUID=%qt%%classGUID%%qt%
}
}

and put above code in the class template :

Code: [Select]


Class
{
 name=%qt%%className%%qt%

 %TRANSFORM_CURRENT("name")%
 %TRANSFORM_REFERENCE("XSDClass")%
%if elemType=="Class"%
%list="Attribute" @separator="\n" @indent="  "%
%endIf%
}

%list="Connector" @separator="\n" @indent="  "%
Dependency
{
%TRANSFORM_REFERENCE("SourceDependency",classGUID)%
stereotype="derivedFrom"
Source
{
  %TRANSFORM_REFERENCE("Class",classGUID)%
}
Target
{
  GUID=%qt%%classGUID%%qt%
}
}
But it did not work. The "derivedFrom" connector didn't appear on the Links tab of the class property.
What's wrong with my code?
Thanks.

I'm probably no good advisor here (I do transformation using the automation). But the Dependency part needs to be put into another macro (say sourceDep). This is then called via %list="sourceDep" @separator="\n" @indent="  "%

You need some kind of guard in sourceDep like
%if connectorType != "Dependency"%
%endTemplate%

There is a way to specify this with %list, but I'm not sure how.

Hi Thomas,

I have tried your suggested way by creating a new template and then called it in the class using %list. It didn't work.

Here is the Class template

Code: [Select]


Class
{
 name=%qt%%className%%qt%

 %TRANSFORM_CURRENT("name")%
 %TRANSFORM_REFERENCE("XSDClass")%
%if elemType=="Class"%
%list="Attribute" @separator="\n" @indent="  "%
%endIf%
}
%list="Connector_derivedFrom" @separator="\n" @indent="  "%
%list="Connector" @separator="\n" @indent="  "%


Here is the Connector_derivedFrom template

Code: [Select]


Dependency
{
%TRANSFORM_REFERENCE("SourceDependency",classGUID)%
stereotype="derivedFrom"
Source
{
  %TRANSFORM_REFERENCE("Class",classGUID)%
}
Target
{
  GUID=%qt%%classGUID%%qt%
}
}


It seems that %list macro would be only executed if there is any template in class with TemplateName as mentioned %list=<TemplateName>.
For example : %list="Attribute" @separator="\n" @indent="  "% --> if there is none Atribute, this will generate nothing instead of generate a new Attribute as I expected.
Am I right in above understanding? (I'm not sure about that)

What I want is, create a new connector with type "Dependency" and stereotype "derivedFrom", so there is no such as connector in the class before. I want this connector exists once on each class, so I think I should put it in the class template, to be executed each time class template executed.

Could you help me please?

Dependency  
{  
%TRANSFORM_REFERENCE("SourceDependency",classGUID)%  
stereotype="derivedFrom"  
Source  
{  
  %TRANSFORM_REFERENCE("Class",classGUID)%  
}  
Target  
{  
  GUID=%qt%%classGUID%%qt%  
}  
}  

can't work. The classGUID is only know in the class' context. There must be something for the connectors. Try to browse through the existing templates...

I have tried remove classGUID, the TRANSFORM_REFERENCE only provide name.
%TRANSFORM_REFERENCE("SourceDependency")%
By default transform reference will gets the GUID of current class. Not works.

Three days searching for the answer and too few documentation and sample make me desperate  

Are there any code template expert who can help me?

Inspire by NUnit Class Template. Finally I did it.
Here are the XSD Class Template code:

Class
{
 name=%qt%%className%%qt%

 %TRANSFORM_CURRENT("name")%
 %TRANSFORM_REFERENCE("MyClass")%
 %if elemType=="Class"%
 %list="Attribute" @separator="\n" @indent="  "%
 %endIf%
}

%list="Connector" @separator="\n" @indent="  "%

Dependency
{
 %TRANSFORM_REFERENCE("SourceDependency",classGUID)%
 stereotype="derivedFrom"
 Source
 {
   %TRANSFORM_REFERENCE("MyClass",classGUID)%
 }
 Target
 {
   GUID=%qt%%classGUID%%qt%
 }
}


I found my fault. It was at the "Source" of "Dependency" code. The TRANSFORM_REFERENCE name must be the same with TRANSFORM_REFERENCE name of the class.
Hope my answer helps the other who have the same problem.
Thanks to God

Well done!

And thanks for the hint.
