Cloning and Inheritance

• Object.clone is paranoid
  • clone is protected
  • clone only clones Cloneable objects
    
  • clone throws checked exception
• You don't have that luxury
• Manager.clone must be defined if Manager adds mutable fields
• Rule of thumb: if you extend a class that defines clone, redefine clone
• Lesson to learn: Tagging interfaces are inherited. Use them only to tag properties that inherit
