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.
