public interface View

A View implements the presentation of a model object to the user and allows interaction with the model object. Implementations can be bound to a model and change the state of the model as the user interacts with the View. If the View implements ModelChangeListener then it can also update in response to changes in the state of bound models that implement ModelChangeEventSource. A View can also issue Controls to its parent Controller in response to user interaction that influences with application logic.

A View is bound to a single model object, i.e. it presents some or all of the data in the bound model.

If a View needs to show data from multiple models, it will be bound to a parent model that contains those multiple models as accessible properties. Think of this parent container as an implementation view model rather than a business/domain model.

A View is created and displayed by a parent Controller the implements application/presentation logic.
