In factory method pattern, the framework must instantiate classes but it only knows about the abstract classes, which it cannot initiate. How would one solve this problem ?
Correct answer: D. all of the mentioned
- A. encapsulating the knowledge of which document subclass to is to be created and
- B. moving this knowledge out of the framework
- C. instantiating the application specific documents without knowing their class
- D. all of the mentioned
Explanation
The Factory Method moves application-specific creation knowledge out of the framework and lets subclasses instantiate the appropriate concrete documents. This allows the framework to work with abstract classes without directly constructing them.
