Detailed Description

Base backend class for KTimeZone classes.

KTimeZone and each class inherited from it must have a corresponding backend class to implement its constructors and its virtual methods, and to provide a virtual clone() method. This allows KTimeZone virtual methods to work together with reference counting of private data.

Note

Classes derived from KTimeZoneBackend should not normally implement their own copy constructor or assignment operator, and must have a non-const d-pointer.
