What the following line is saying about model component in MVC pattern:
If the model adheres to a strict
contract (interface). then these
components can be reused in other
application areas such as GUIs or
J2ME.
Does the above line mean, if the model components implement any interface based on any GUI and J2ME application, then these application can use it. Am I correct?
In the MVC pattern, the model should have no knowledge of what type of application or user interface is using it. It should only provide methods to access the data, and should not care what type of application is calling it. The quote you have means that if your model has a well-defined, non-application-specific interface, it can be used in any type of presentation (e.g. a GUI or J2ME mobile app, etc.)
