It checks that the class does not already exist. 
And check the preconditions. 

Le 9/2/16 16:41, Peter Uhn��k a ��crit :

What's the practical difference between calling

```
(RBAddClassRefactoring
                addClass: #SomeClass
                superclass: #Object
                subclasses: {}
                category: #Category) primitiveExecute; changes.
```
and
```
Object subclass: #SomeClass
instanceVariableNames: ''
classVariableNames: ''
package: 'Category'
```

likewise for the attribute?

I am doing source code generation in one project and using the latter approach, so I am curious about the benefit of the first one.

Thanks,
Peter
