Create a copy of the class on the heap.
The exact semantics of the descendent class determine what is required to make a duplicate of the instance. Not all classes can even do a clone operation.
The main user of the clone function is the PDictionary
class as it requires copies of the dictionary keys.
The default behaviour is for this function to assert.
- Returns
- pointer to new copy of the class instance.
Reimplemented from PObject.
