Class BajaDataProvider

java.lang.Object
  |
  +--oracle.cabo.servlet.ui.data.BajaDataProvider

All Implemented Interfaces:

DataProvider

public class BajaDataProvider

extends java.lang.Object

implements DataProvider

DataProvider for serving all the UIX Servlet related state. This DataProvider will serve the following DataObjects:

• If the EventResult is a UIEventResult, any DataObjects served by its DataProvider.
• ctrl:page: Page properties
• ctrl:pageState: State properties for current Page
• ctrl:eventResult: EventResult properties
• ctrl:httpSession: HttpSession properties
• ctrl:servletContext: ServletContext properties
• ctrl:servletRequest: ServletRequest attributes

Note that for servlet requests, we serve up the attributes, not the parameters. This DataProvider will own all requests for the UIX Servlet namespace - if added, any other data providers that attempt to serve the UIX servlet namespace may be rejected.

This class will automatically be attached when using a BajaRenderingContext, and it in fact relies on the BajaContext and Page being stored on a RenderingContext in the same places as BajaRenderingContext stores them.
