Method Detail

getLayoutStrategy

public String getLayoutStrategy()

Returns the text of the layoutStrategy attribute that corresponds to this BorderLayout portal component. Will be either BorderLayout.LAYOUT_BY_ORDER or BorderLayout.LAYOUT_BY_TITLE. LAYOUT_BY_ORDER will arrange the Placeholders in order based on their position in the layout (e.g. the first Placeholder listed will be "north", the next will be "west", etc.). LAYOUT_BY_TITLE will arrange the Placeholders based on their title. Placeholders with no title attribute or with a title attribute whose value is not one of "north", "west", "center", "east", or "south" will be ignored and not rendered. In the case of multiple placeholders with the same title, only one will be rendered - which one is not defined.

Returns

The text of the layoutStrategy attribute as a String. If unspecified in the .layout file, BorderLayout.LAYOUT_BY_ORDER is returned.

getBorderLayoutPresentationContext

public static BorderLayoutPresentationContext getBorderLayoutPresentationContext(HttpServletRequest request)

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