Hi,

This link will have all the classes information and search for the API classes you wanted to know more about

http://help.sap.com/javadocs/nwce/current/wdr/allclasses-frame.html

ex: IWDController interface is an API of all Web Dynpro controllers

Thanks

Hi

1) Controller Shortcut Variables

private final IPrivate wdThis; private final IPrivate.IContextNode wdContext;

private final IWDViewController wdControllerAPI;

private final IWDComponent wdComponentAPI;

public (IPrivate wdThis) {

this.wdThis = wdThis;

this.wdContext = wdThis.wdGetContext();

this.wdControllerAPI = wdThis.wdGetAPI();

this.wdComponentAPI = wdThis.wdGetAPI().getComponent();

}

2) Within any Web Dynpro controller, three shortcut variables are always present, whose values are all derived from the member variable wdThis.wdThis is the Web Dynpro specific self reference and should be used in preference to the standard Java self reference of this.

3) The member variable wdThis is populated from a parameter of the same name, passed in by the Web Dynpro framework when the controller is instantiated.

wdThis is refernece pointing to web dynpro ( entity )object (like view controller, component controller etc)

All other terms you mentioned are interface to represent each web dynpro entity. e.g each View Controller implements IWDViewController.. and same for others.

Please refer to sample tutorials to learn how to use them.
