Interface IScreenflow
- All Known Implementing Classes:
- AbstractScreenflow
- public interface IScreenflow
encapsulates both the definition of a dynamic screenflow as well as the
firing of the needed event to actually navigate into this screenflow.
Implementing classes add the complete screenflow they need into a given
screenflow definition. In the case of the WDF, this means, that they add
the needed PaneElements and ControlElements to the
given ControllerDynPage. As the last step, the class must add
a NextScreenElement to the current PaneElement that
is to be replaced by the first and outermost PaneElement of the
class. The WdfEvent that triggers this transistion is the one that
must be returned by the execute method.
When the user navigates within a single iView for some time, more and more
IScreenflows will be added to the screenflow definition. This also
means that PaneElements or ControlElements with the same
ID could be added to this definition with unexpected and unwanted effects - wrong or
missing parameterization could be the result. Therefore, implementing classes must
add their classname in front of any elements that are created and added to the
screenflow definition.
