public class MenuPresentationContext
extends PresentationContext

This class represents a portal menu component. All presentation-related attributes of a menu component are available from instances of this class. Such instances are typically used during portal rendering via look and feel skeleton files (e.g. singlelevelmenu.jsp, multilevelmenu.jsp).

This class exposes the render-related attributes of a generic menu, but the actual structural data it uses to generate the menu itself comes from it's parent BookPresentationContext.

The presence of an instance of this class indicates that a tabbed menu (of 'n' levels) should be rendered for the parent book.

public static MenuPresentationContext getMenuPresentationContext(javax.servlet.http.HttpServletRequest request)
This is a convenience method for returning a reference to the current MenuPresentationContext. Note this method will only work if called from within a portal (typically, from the singlelevelmenu.jsp or the multilevelmenu.jsp skeleton). This method may return null if called when no appropriate context exists, but such a context should safely exist when being fetched from the associated skeleton JSP during normal portal rendering.

request - The current HTTPServletRequest instance
A reference to the current MenuPresentationContext, if any


public BookPresentationContext getBookPresentationContext()

Get the presentation context for the parent book.

Will return null if the menu is not nested within a book.
