Functionality

The connectors are controllers that are responsible for the individual input and output fields on the HTML page. The connectors establish the link between the view and the domain model.

All connectors are registered on the view and wait for the proxy objects in the view (= screen elements)to be instantiated. As soon as a screen element has been generated, the corresponding connector callsup all necessary data of the fields in the domain model and sets it in the view by invoking the corresponding screen element methods.

Relationships

Abstract superclass of all connectors.

Example

Notes

Comment:

For performance reasons, the connectors do not register themselves on the event (-> exponential increasein registrations), but only register themselves on their superclass CL_CONNECTOR_POC. The latter is itself registered as the only one on the event.

To the connectors it is irrelevant which class the screen element has. It is merely checked which interfacesthe screen element implements (IF_AC_*_POC). Each interface describes certain properties of the element. Each connector holds the interface references only, not the actual object reference.
