Direct Known Subclasses:

BookPresentationContext

public class PagePresentationContext
extends WindowPresentationContext

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

Method Detail

isHidden

public boolean isHidden()

A hidden page is a page that does not show up as a tab in a book's menu. It may still be activated via links and events, however.

Returns

True, if this is a hidden page

isActive

public boolean isActive()

Return true if this page is active. Note this is different from isDisplayed() in that an active page is not necessarily always displayed, since the parent book may not itself be active. Active pages can have an inactive parent book but when the parent is activated again the current page is remembered.

Returns

True, if the page is active.

isVisible

public boolean isVisible()

Returns true if this page is visible. Note that this is different from isDisplayed() and isActive(). Generaly this method is useless as the pages that are not being displayed are suspended and never get visible set to false. It is recommended that you use isDisplayed() or isActive() instead.

Overrides:

isVisible in class PresentationContext

Returns

True if the page is visible

isDisplayed

public boolean isDisplayed()

Return true if this page is being displayed. Note that this is different from isActive() in that an active page is not necessarily always displayed, since the parent book may not be active.

Returns

True, if the page is displayed

getLabel

public String getLabel()

Return the label for this page. This is equivalent to calling WindowPresentationContext.getDefinitionLabel().

Specified by:

getLabel in class WindowPresentationContext

Returns

The page's label

getWindowPresentationContexts

public List getWindowPresentationContexts()

Return the collection of child WindowPresentationContexts (BookPresentationContext or PortletPresentationContext) for this page. If no child portlets and books exist, this returns an empty list.

Returns

A list of BookPresentationContext and PortletPresentationContexts objects

getActiveImage

public String getActiveImage()

Returns the webapp-qualified path to a fully skinned, classified, localized, and themed image to be displayed when this page is active. Such an image may be optionally displayed in the page tab of it's parent book's menu. This setting is optional, so this method may return null.

Returns

The path to the active image for this page; null if not set

getInactiveImage

public String getInactiveImage()

Returns the webapp-qualified path to a fully skinned, classified, localized, and themed image to be displayed when this page is inactive. Such an image may be optionally displayed in the page tab of it's parent book's menu. This setting is optional, so this method may return null.

Returns

The path to the active image for this page; null if not set

getRolloverImage

public String getRolloverImage()

Returns the webapp-qualified path to a fully skinned, classified, localized, and themed image to be displayed when this page is inactive. Such an image may be optionally displayed in the page tab of it's parent book's menu. This setting is optional, so this method may return null.

Returns

The path to the active image for this page; null if not set

getBookPresentationContextRecursive

public BookPresentationContext getBookPresentationContextRecursive(String definitionLabel)

Returns a book, searching the entire tree recursively. If you are interested in both books AND pages use getPagePresentationContextRecursive(java.lang.String) as that method returns both.

Parameters

definitionLabel - The definitionLabel of the desired book

Returns

The Book of interest or null if not found.

getPagePresentationContextRecursive

public PagePresentationContext getPagePresentationContextRecursive(String definitionLabel)

Returns a book or a page but traverse the entire tree; this will go inside books that are on pages too.

Parameters

definitionLabel - The definitionLabel of the desired page

Returns

PagePresentationContext (or BookPresentationContext if a book) of the page or book with a matching definition label

getPortletPresentationContextRecursive

public PortletPresentationContext getPortletPresentationContextRecursive(String instanceLabel)

Returns the PortletPresentationContext matching the supplied instance label.

Parameters

instanceLabel - The Unique instance label of the desired portlet

Returns

A reference to the PortletPresentationContext if it exists; null otherwise

getPortletsPresentationContextRecursive

public PortletPresentationContext[] getPortletsPresentationContextRecursive(String definitionLabel)

Returns an array of PortletPresentationContexts matching the supplied definition label. Since many portlets can share the same definition label, more then one portlet can be returned. If you are interested in just one portlet then try getPortletPresentationContextRecursive(java.lang.String).

Parameters

definitionLabel - The label of the portlet(s)

Returns

A non-null array of PortletPresentationContexts

getParentBookPresentationContext

public BookPresentationContext getParentBookPresentationContext()

Get the presentation context for the parent book.

May return null if the page is not nested within a book.

getPagePresentationContext

public static PagePresentationContext getPagePresentationContext(javax.servlet.http.HttpServletRequest request)

This is a convenience method for returning a reference to the current PagePresentationContext. Note this method will only work if called from within a portal (typically, from the page.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.

Parameters

request - The current HTTPServletRequest instance

Returns

A reference to the current PagePresentationContext, if any
