/**
|
|
* Base class for filtering the subtree for certain node statuses.
|
|
*
|
|
* The simplest way of building a CMSSiteTreeFilter is to create a pagesToBeShown() method that
|
|
* returns an Iterator of maps, each entry containing the 'ID' and 'ParentID' of the pages to be
|
|
* included in the tree. The reuslt of a DB::query() can be returned directly.
|
|
*
|
|
* If you wish to make a more complex tree, you can overload includeInTree($page) to return true/
|
|
* false depending on whether the given page should be included. Note that you will need to include
|
|
* parent helper pages yourself.
|
|
*
|
|
* @package cms
|
|
* @subpackage content
