Code generation during generation of .gmfgen file [message #545025]

hi all

my idea was to change the code for the figures used for all nodes in an editor in the codegen templates. but after some searching i found out that this code is already generated during creation of the .gmfgen file (it is located in the 'classBody' attribute of the 'viewmap' of each node in the 'GenDiagram').

since this code is also generated (and has the usual '@generated' comments), i guess there must be templates for the generation somewhere. so my question is, does anybody know where this templates are located and what's the best way to change them (if any)?

thanks in advance

Hi,

there are two options for the gmfgen creation you may choose at gen
model creation wizard's the last page:
- java transformation (the default one)
- qvto transformation

and you may choose dynamic templates.

The java transformation is done with the TransformToGenModelOperation
class. The transformation might be executed outside the wizard too. And
you might customize the operation for your own purpose.

Abstract:

ResourceSet resourceSet = ...
org.eclipse.emf.codegen.ecore.genmodel.GenModel genModel = ...
org.eclipse.gmf.mappings.Mapping mapping = ...

org.eclipse.gmf.internal.bridge.transform.TransformToGenMode lOperation
operation = new
org.eclipse.gmf.internal.bridge.transform.TransformToGenMode lOperation
(resourceSet);

operation.loadMappingModel(mapping.eResource().getURI(), progressMonitor);
operation.loadGenModel(genModel.eResource().getURI(), progressMonitor);

operation.setGenURI(gmfGenUri);
org.eclipse.gmf.internal.bridge.transform.TransformOptions options =
operation.getOptions();
options.setUseMapMode(true);
options.setUseRuntimeFigures(true);
options.setFigureTemplatesPath(null);
options.setTransformation(null);
options.setPreReconcileTransform(null);
options.setPostReconcileTransform(null);

IStatus transformationResult =
operation.executeTransformation(progressMonitor);

hi sven

thanks for your in-depth answer. i think the dynamic templates thing is what i'm looking for.
as far as i understand, the 'dynamic templates' field takes the path to my templates folder, right?
so now i only have to find out where the default templates are located.
are they in 'org.eclipse.gmf.codegen' too? didn't look like that.
any hints appreciated.

cheers

Hi Marco,

I've never used the qvto transformation explicitly. But based on my
experiences: I would expect an full qualified path
(platform://resources/youryPlugin/path).

take a look at
org.eclipse.gmf.internal.bridge.transform.TransformToGenMode lOperation.createGenModelProducer(VisualIdentifierDispenserP rovider)
....
{
URI transfURI =
URI.createURI(getOptions().getMainTransformation().toExterna lForm());
QvtoTransformationHelper helper = new
QvtoTransformationHelper(transfURI);
}

hi sven

uhm, if i understand you right, you suggest to find the path to the default templates by looking into the code?
i do not really understand what's going on there, not sure where the path is taken from.
i guess things like default paths must be in some config file, but i wasn't able to find them yet...
not sure how things like that are handled in eclipse...
i'll now check the dependencies for the templates.
if someone else has an idea, please let me know.

cheers marco

hi stéphane

thanks for your answer. i know this link, but as far as i see they only
use the codegen templates that are used for generating the code
from the .gmfgen model.
but i am looking for the templates that are used in an earlier step
during creation of the .gmfgen model itself (there is some code
generated into the model, see first post).
and as far as i can see the templates for that are not in 'org.eclipse.gmf.codegen'.

cheers

Hi,

why don't you use Custom Figure in the .gmfgraph?

Regards,

hi aurelien

well, all i want to do is
a) change the content of the labels in my figure
b) add listeners so the labels get updated on model change
i don't know if using a custom figure (as the main figure i guess?) would help me in this case.
but since i'm not sure how custom figures work, i'll have a look.

cheers

ok, finally found the templates...
in case anyone else is interested:

they are located in package:

org.eclipse.gmf.graphdef.codegen

to use them, add a root template dir to your project folder, and copy the templates you need (including folder structure!) into it.
in the last step of the "create generator model" wizard you can set the "GMFGraph dynamic templates" root folder.

cheers
