Can trigger a method call for an attribute change in an EMF model? [message #1059569]

Hi there,

Can I trigger a method call for an attribute change in an EMF model?

I need to call a validation method for an EMF attribute change. I am just wondering, if this type of functionality is possible with EMF models?

Any idea/help is appreciated.

Cheers,
Kosala

Kosala,

You can add an adapter to any EObject and listen for changes. Your
question is without much context though. What will this validation do?
How is the result of the validation used in the tool?

Hi Ed,

Thanks.

Attribute changes in an EMF model need to trigger OCL rules validation. OCL rules validate EMF model for changed attributes, and error results(if available) are displayed on the tool.

Kosala,

The latest version of EMF supports generating a live validator that will
revalidate all the instrinct constraints in the model after each command
stack execution. It's possible to expression such constraints using
OCL; you can look at that project's documentation.

Kosala,

You'd need to install a Kepler version of EMF. I think that would
install into Indigo...

There's no documentation other than my blog:
