This package provides a family of controllers that interface between the model provided by EVBRESTClient and the presentation views provided by EVBRestUI.
All of these controller classes provide the following options:
-model
An EVBRestClient that will
be used as the model in the MVC triad. The
client must be properly configured and the same client can,
and often will be shared between controllers.
-viewShould be the view instance associated with the specific controller (see CONTROLLER VIEW PAIRS below).
All controllers have exactly one public method: update
which takes no parameters. Prior to the first call of
update
the object must be fully configured with a valid
-model and -view. What
update does is request the appropriate
statistics from the model and then configure them in the
appropriate option of the view. In a normal application,
this will be done periodically, e.g. from a rescheduled
after.
Each controller class in this package must be paired with the correct view or a compatible view like object. The table below assumes you are pairing a controller with its compatible view in the EVBRestUI package.
