Hi,
I'm building a dynamic ecore model and creating instances of that model. And my question is how can I add constraints to my dynamic model attributes that can be checked by the validation framework.
Let say I have a following code example:
EcoreFactory ecoreFactory = EcoreFactory.eINSTANCE;
EClass productClass = ecoreFactory.createEClass();
productClass.setName( "Product" );
EAttribute name = ecoreFactory.createEAttribute();
productClass.getEStructuralFeatures().add( name );
name.setName( "name" );
name.setEType( EcorePackage.eINSTANCE.getEString() );
EAttribute price = ecoreFactory.createEAttribute();
productClass.getEStructuralFeatures().add( price );
price.setName( "price" );
price.setEType( EcorePackage.eINSTANCE.getEDouble() );
And my goal is to add a min and max values constraints to the 'price' attribute.
Any working example will be appreciated.
Thanks,
Michal

Hi
The OCLinEcore tutorial is a working example in Help->Help Contents->OCL
Documentation.
