Abstract class to define functionality shared by all pluggable components used in the question bank view.| __construct(view $qbank) X-Ref |
| Constructor. param: view $qbank the question bank view we are helping to render. |
| init() X-Ref |
| A chance for subclasses to initialise themselves, for example to load lang strings, without having to override the constructor. |
| get_extra_joins() X-Ref |
| Return an array 'table_alias' => 'JOIN clause' to bring in any data that this feature requires. The return values for all the features will be checked. It is OK if two features join in the same table with the same alias and identical JOIN clauses. If two features try to use the same alias with different joins, you get an error. Tables included by default are question (alias q) and those defined in {@see view::get_required_joins()} It is importnat that your join simply adds additional data (or NULLs) to the existing rows of the query. It must not cause additional rows. return: string[] 'table_alias' => 'JOIN clause' |
| get_required_fields() X-Ref |
| Use table alias 'q' for the question table, or one of the ones from get_extra_joins. Every field requested must specify a table prefix. return: string[] fields required. |
