xpt templates [message #504673]

Hi,

In my diagram project, I changed A specific editpart, called FBEditPart,
which is located in diagram.edit.parts.FBEditPart.

I just added a new method and some inner classes. Now I'd like to use a
template so the code is generated automatically. So I made an new
template file NodeEditPart.xpt

Is it enough to simply add a new Define statement or do I have to change
an existing one?

And how can I specify that I want only FBEditPart to be affected and not
other EditParts?

Currently, my NodeEditPart.xpt looks like this:

------------------------------------------------------------
«IMPORT 'http://www.eclipse.org/gmf/2009/GenModel'»
«EXTENSION xpt::diagram::ViewmapAttributesUtils»
«EXTENSION xpt::diagram::editparts::Utils»
«EXTENSION xpt::diagram::Utils»

«DEFINE additions FOR gmfgen::GenNode-»
«IF ----- only true if this is an FBEditPart ------»
----- method code -----
----- class1 code -----
----- class1 code -----
----- class1 code -----
«ENDIF-»
«ENDDEFINE»
------------------------------------------------------------

Is this the right approach?

Thanks,
Matthias

Hi Matthias,

You should use AROUND keyword instead of DEFINE to customize code
generation from your *.gmfgen. You should also look at UML2Tools source
code to see how they do.

Best Regards.

Hi,

I figured out, how to do it: It is possible to add custom code to the
'additions' DEFINE statement. This is expanded after all the other code
of the NodeEditPart is generated. In addition, GenNodes have the string
attribute 'editPartClassName', so I can simply test if that one is equal
to 'FBEditPart'.

However, I keep getting a strange error message:

Problems while generating code
Exception (org.eclipse.gmf.internal.xpand.util.ParserException,
@aspects::diagram::editparts::NodeEditPart
[131:33-131:33] "ERROR_TOKEN"unexpected token(s)
ignored(aspects::diagram::editparts::NodeEditPart:131:33:131 :33: ))
while generating code

ignored(aspects::diagram::editparts::NodeEditPart:131:33:131 :33: ))
..
..
..
(This is repeated several times)

It looks like a syntax error, but I cannot figure it out. Does anyone
know, what is wrong here?

Thanks in advance,
Matthias

This is my additions rule in NodeEditPart.xpt:

«DEFINE additions FOR gmfgen::GenNode-»
«IF self.editPartClassName == "FBEditPart"-»
protected void handleNotificationEvent(Notification notification) {
super.handleNotificationEvent(notification);
...
}

public class FBCommand extends Command {
...
}

public class FBDeleteEventsAndVarsCommand extends FBCommand {
...
}

public class FBAdaptEventsAndVarsCommand extends FBCommand {
...
}
«ENDIF-»
«ENDDEFINE»

Hi again,

I just tried to generate my diagram code with an old template, which
used to work. I get the same error here. This must mean that it's not a
syntax error. However, I have no idea what to make of this.

Regards,
Matthias

Hi laura,

Have you tried with AROUND statement instead of DEFINE statement and by
adding all dependants DEFINE statements of the statement you want to
customize?

Hi Esteban, and thanks for your answer.

My problem is when I try to add some IF statements, because I am interested in modify the code ONLY for some elements.

In old xpt files I used for a node:
IF this.elementType.displayName.compareTo("nameOfMyType") == 0 and it works perfectly...I can't figure out how to solve this now, I think it is a problem of dependences.

Have you tried this anyway?

Thanks Smile

Hi Laura,

Do you override the impl/diagram/editparts/NodeEditPart.xpt template?
Which release of GMF do you use?
I have a example of GMF templates customization at
https://gforge.inria.fr/scm/viewvc.php/trunk/v1/plugins/fr.i nria.adam.calico.models.application.ui.editors.graphical/mod els/m2t/aspects/impl/diagram/editparts/?root=calico
if it can help.

I use Eclipse Helios M6.

Can you show your template customization?

Thanks a lot Esteban!

I use the IF statements as you do in your xpt template and it works!

I tried to make the condition dependant of the node type name but I get an error.
Also, I tried to use the OR in the IF statement like this:

«IF getEditPartQualifiedClassName() = 'com.ptb.rad.bpmn.emf.bpmn.diagram.edit.parts.ManualTaskEdit Part'
|| getEditPartQualifiedClassName() = 'com.ptb.rad.bpmn.emf.bpmn.diagram.edit.parts.ManualTask2Edi tPart' »
«EXPAND ..... »

without sucess, I have to use IF and ELSEIF as you :S

At least it works fine!
Thanks again!
