All Implemented Interfaces
  Serializable

Direct Known Subclasses:
  BookBackingContext

    public class PageBackingContext

extends WindowBackingContext

This is the backing context for a page. As such, it is meant to be called from backing files or pageflows. If you want to access this context from a JSP, look at PagePresentationContext instead.

Call `getContextFromRequest` to obtain the backing context for the active window.

Field Detail

### CLASS_NAME

    protected static final String CLASS_NAME

Method Detail

### getLabel

    public String getLabel()

  Returns the definition label on the page

  Specified by:
    `getLabel` in class `WindowBackingContext`
  Returns
    the definition label of the page

### getParentBookBackingContext

    public BookBackingContext getParentBookBackingContext()

  Returns the BookBackingContext of the book that is the parent of the page represented by this context.

  Returns
    the BookBackingContext of the Book that is the parent of the page represented by this context, or null if there is no parent book.
  See Also
    `Page.getBook()`

### getMarkupName

    public String getMarkupName()

  Returns the value of the Page's markupName attribute.

### getMarkupType

    public String getMarkupType()

  Returns the value of the Page's markupType attribute.

### getParentPageBackingContext

    public PageBackingContext getParentPageBackingContext()

  Returns the PageBackingContext of the Page that is the parent of the page represented by this context.

  Overrides:
    `getParentPageBackingContext` in class `WindowBackingContext`
  Returns
    the PageBackingContext of the Page that is the parent of the Page represented by this context or null if there is no parent page.
  See Also
    `Page.getParentPage()`

### 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 as the parent book may not 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/book is active.

### isHidden

    public boolean isHidden()

  Return the value of the underlying object's `hidden` attribute. 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
    a boolean, the value of the underlying object's `hidden` attribute.

### setActive

    public void setActive(boolean active)

  Set the value of the underlying object's `active` attribute. 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.

  Parameters
    `active` - boolean, the new value of the underlying object's `active` attribute.

### setHidden

    public void setHidden(boolean hidden)

  Set the value of the underlying object's `hidden` attribute.

  Parameters
    `hidden` - boolean, the new value of the underlying object's `hidden` attribute.

### getPageBackingContext

    public static PageBackingContext getPageBackingContext(javax.servlet.http.HttpServletRequest request)

  Get the PageBackingContext from the request

### getActiveImage

    public String getActiveImage()

  Get the path to the image displayed in the menu tab when the page is active.

  Returns
    the path to the image

### setActiveImage

    public void setActiveImage(String activeImage)

  Set the path to the image displayed in the menu tab when the page is active.

  Parameters
    `activeImage` - a uri to the new activate image.

### getInactiveImage

    public String getInactiveImage()

  Get the path to the image displayed in the menu tab when the page is inactive.

  Returns
    the path as defined in the IDE for the image when the page is inactive.

### setInactiveImage

    public void setInactiveImage(String inactiveImage)

  Set the path to the image displayed in the menu tab when the page is already active.

  Parameters
    `inactiveImage` -

### getRolloverImage

    public String getRolloverImage()

  Get the path to the rollover image to be displayed on the menu tab for this page.

### setRolloverImage

    public void setRolloverImage(String rolloverImage)

  Set the path to the rollover image to be displayed on the menu tab for this page.

  Parameters
    `rolloverImage` -

### isDisplayed

    public boolean isDisplayed()

  Return true if this page is going to be displayed. This method should be called late in the lifecycle `preRender()` to determine if this page will be displayed. If called earlier in the lifecycle `handlePostBackData()` it will return true if the page was previously display.

  Note: this is different from `isActive` in that an active page is not necessarily always displayed as the parent book may not be active.

  Returns
    true or false

### getWindowBackingContexts

    public List getWindowBackingContexts()

  Return the collection of chils WindowBackingContexts (BookBackingContext or PortletBackingContext) for this page. If no portlets and books exist returns an empty list.

  Returns
    List of `BookBackingContext and PortletBackingContext`s objects

### getBookBackingContextRecursive

    public BookBackingContext getBookBackingContextRecursive(String definitionLabel)

  Return a book searching the entire tree recursively. If you are interested in both books AND pages use `getPageBackingContextRecursive()` as that method returns both.
  Note: this method may return null if called from the init() method of a backing context.

  Parameters
    `definitionLabel` - of the book
  Returns
    the Book of interest or null if not found.

### getPageBackingContextRecursive

    public PageBackingContext getPageBackingContextRecursive(String definitionLabel)

  Return a book or a page but traverse the entire tree. The search will go inside books that are on pages too.
  Note: this method may return null if called from the init() method of a backing context.

  Parameters
    `definitionLabel` -
  Returns
    pageBackingContext or (BookBackingContext if book) of the page or book with matching definition label.

### getPortletBackingContextRecursive

    public PortletBackingContext getPortletBackingContextRecursive(String instanceLabel)

  Return the portlet backing context matching the supplied instance label.
  Note: this method may return null if called from the init() method of a backing context.

  Parameters
    `instanceLabel` - unique instance label of the portlet
  Returns
    a reference to the portlet's BackingContext if it exist otherwise null.

### getPortletsBackingContextRecursive

    public PortletBackingContext[] getPortletsBackingContextRecursive(String definitionLabel)

  Return portlet backing contexts 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 `getPortletBackingContextRecursive(String instanceLabel)`.
  Note: this method may return null if called from the init() method of a backing context.

  Parameters
    `definitionLabel` - label of the portlet
  Returns
    a non null array of PortletBackingContext.
