How to set NAME_EDEFAULT [message #792648]

Hi

Is it possible to set NAME_EDEFAULT for an EClass somewhere in the model
generator or in the model itself, maybe using the Ecore diagram editor?

Currently we are doing this to set the default name for each impl class
generated:

public class LongImpl extends SimpleTypeImpl implements
org.best_of_robotics.bride.datatypes.Long {
/**
* @generated NOT
*/
protected LongImpl() {
super();
name = "long";
}
....

since SimpleTypeImpl has:

public abstract class DataTypeImpl extends EObjectImpl implements DataType {

protected static final String NAME_EDEFAULT = null;
protected String name = NAME_EDEFAULT;
....

Thanks

You'll need to use the properties view to set the default value literal
property of the attribute.

Is the name feature defined in LongImpl or in a base class?

If you had to force it (which you don't) why wouldn't you change the
value of this declaration? After all, you'll notice that this value is
used to determine the result of eIsSet...

A base class. Guess we have to do a push down refactoring and add the
name attribute to each subclass and then set a default value for it?

or set this in each subclass in the code and use @generated NOT?

What would be best practice?

Ok, so the solution is to use Interfaces as super types and thus the
generator will produce an implementation code for each field declared in
the interface.
