public interface Model

Responsible for the state of a component. Model's can be state-full or non-state-full. By default Models are non-state-full. Non-state-full models are models whose state dies when its enclosing page loses its visibility. On the other hand, the state in state-full models lives on when its enclosing page loses its visibility. The state in state-full models is kept alive by persisting it on the client browser in hidden HTML input elements, cookies or some other client storage mechanism. Do not confuse this persistence with the server side persistence provided AbstractThreadLocalModel.

State is transferred to a model when a HTTP request is received from the client and extracted from it when a HTTP response is sent to the client. Under default operation this process is handled dynamically by the controller using the Java Bean design pattern. When applying state, the controller examines the model for member functions with the following properties:

• name begins with set
• the name suffix following set matches the name of the HTTP request parameter
• returns void
• accepts one argument of the proper type

It then calls these functions to apply the incoming state to the model. When extracting state, the controller examines the model for member functions with the following properties:

• name begins with get
• accepts zero arguments

It then calls these functions to extract the state of the model. The developer must be cognizant of these rules when naming member functions on models.
