public class LayoutPresentationContext
extends PresentationContext

Used to provide access to presentation-related attributes specific to the Layout in use. Typically used during portal rendering via look and feel skeleton files. The skeleton file name for a Layout portal component must be <type>layout.jsp, where <type> is the string specified by the type attribute in the Layout portal component. For example:

<netuix:layout type="custom" title="Custom Layout" ...>

will delegate rendering tasks to customlayout.jsp in your skeleton directory.

Method Detail

getType

public String getType()

Returns the text of the type attribute that corresponds to this Layout portal component.

Returns

The text of the type attribute as a String, if any

getPlaceholders

public List getPlaceholders()

This is a convenience method for getting PlaceholderPresentationContexts for all placeholder children of this layout. The same functionality can be achieved by calling PresentationContext#getChildren().

Returns

A list containing PlaceholderPresentationContexts of all immediate placeholder children of this layout, or null if no placeholder children exist.

getLayoutPresentationContext

public static LayoutPresentationContext getLayoutPresentationContext(javax.servlet.http.HttpServletRequest request)

This is a convenience method for returning a reference to the one and only LayoutPresentationContext. Note this method will only work if called from within a portal. 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 LayoutPresentationContext, if any
