Detailed Description

Visitor that helps to perform action that depends on polymorphic object type.

Use cases:

• data serialization,
• pretty printing of CCObject *
• safe value reading from CCArray, CCDictionary, CCSet

Usage:

1. subclass CCDataVisitor
2. overload visit() methods for object that you need to handle
3. handle other objects in visitObject()
4. pass your visitor to CCObject::acceptVisitor()
