Base class for all report filters
Filters provide a form for collecting user input, and then return appropriate SQL fragments based on these values

| __construct(filter $filter) X-Ref |
| Do not allow the constructor to be called directly or overridden param: filter $filter |
| create(filter $filter) X-Ref |
| Creates an instance of a filter type, based on supplied report filter instance The report filter instance is used by reports/entities to define what should be filtered against, e.g. a SQL fragment param: filter $filter The report filter instance return: static |
| get_header() X-Ref |
| Returns the filter header return: string |
| get_entity_name() X-Ref |
| Returns the filter's entity name return: string |
| get_filter_persistent() X-Ref |
| Returns the filter persistent Note that filters for system reports don't store a persistent and will return null. return: filter_model|null |
| applies_to_values(array $values) X-Ref |
| Given an array of current filter values for the report, determine whether the filter would apply to the report (i.e. user has configured it from it's initial "Any value" state). A filter would typically be considered applied if it returns SQL filter clauses, but child classes may override this method if they use different logic param: array $values return: bool |
| get_sample_values() X-Ref |
| Return sample filter values, that when applied to a report would activate the filter - that is, cause the filter to return SQL snippet. Should be overridden in child classes, to ensure compatibility with stress tests of reports return: array |
