/** |
| 44 |
* The abstract WebExplorer_Module_AbstractNavigationList class |
| 45 |
* includes the base/common/generic infrastructure to display |
| 46 |
* a table of navigation links which point to arbitrary other items. |
| 47 |
* |
| 48 |
* The structure making up the navigation table is loaded from |
| 49 |
* an arbitrary data source. It contains information about labels |
| 50 |
* urls, alt-texts and such. |
| 51 |
* |
| 52 |
* It handles the actual querying of data sources for child classes |
| 53 |
* inheriting from it. |
| 54 |
* |
| 55 |
* It's using the DataSource::Generic chain to access the common |
| 56 |
* backend datasource query API (queryData/querySchema). |
| 57 |
* |
| 58 |
* Metadata about the data source access is bundled inside a |
| 59 |
* helper object called Data::Locator. |
| 60 |
* |
| 61 |
* The results - probably a simple list - are displayed inside |
| 62 |
* a VerticalCSSNavTable. For being able to handle arbitrary |
| 63 |
* results here, the 'propagate' method has to be overwritten. |
| 64 |
* |
| 65 |
* The links contain http query arguments which should trigger |
| 66 |
* the request processor (MVC) to navigate into the selected |
| 67 |
* top-level node. |
| 68 |
* This displays a list of second level nodes inside the content area |
| 69 |
* which are most probably full blown row-based results. |
| 70 |
* (ms-lingo: recordsets) |
