Implementing Components with their Controllers and Interfaces 
In this section the Web Dynpro controller and interface concept is illustrated in a concrete sample component. Based on some controller-specific declarations the IPrivate- and IPublic-APIs are extended by the Code Generation Framework of the Web Dynpro Tools.
The sample component comprises three controllers:
Component controller SampleComp
Window controller SampleWin
View controller SampleView
Procedure
Programming Tasks
The sample code blocks of the next three sections demonstrate how to solve typical programming tasks by invoking the generated controller interfaces IPublic- and IPrivate in the application code. These interfaces are based on the declarations (like methods, events, controller usages, actions or plugs) done by the application developer.
