Re: [Pharo-users] how to add a class via programatic refactoring

Feb. 9, 2016


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

Le 9/2/16 16:41, Peter UhnÃ¡k a Ã©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
