`Protected`calculateClassKey

calculateClassKey(clas: ClassType): string
Calculates a key for a class which encodes its unique properties, i.e. duplicate classes have the same key. This key is used to identify duplicated classes. Override this method to change the properties which make a class unique.
Parameters
- clas: ClassType
  the current class type
Returns string
a string key
