inlineinherited |
Copies all relations of sourceObj (pointing from or to sourceObj) to this object (including weights).
Useful if you want to make a complete copy of a StoreArray object to make modifications to it, but retain all information on linked objects.
Note: this only works if sourceObj inherits from the same base (e.g. RelationsObject), and only for related objects that also inherit from the same base.
