Hi, Stefan,
This works because EClassifiers intern() their instance-class names, and
Java ensures that string constants are interned, so this is actually
more efficient than .equals() and it's correct.
Cheers,
Christian

protected void basicSetInstanceClassName(String value)
{
if (instanceClassName == null && generatedInstanceClassName != null)
{
instanceClassName = generatedInstanceClassName;
generatedInstanceClassName = null;
}
setInstanceClassNameGen(value == null ? null : value.intern());
if (instanceClass != null)
{
setInstanceClassGen(null);
}
}
