Represents a document to index.
Note that, if you are writting a search engine and you want to change \core_search\document
behaviour, you can overwrite this class, will be automatically loaded from \search_YOURENGINE\document.

| __construct($itemid, $componentname, $areaname) X-Ref |
| We ensure that the document has a unique id across search areas. param: int $itemid An id unique to the search area param: string $componentname The search area component Frankenstyle name param: string $areaname The area name (the search area class name) return: void |
| add_stored_file($file) X-Ref |
| Add a stored file to the document. param: \stored_file|int $file The file to add, or file id. return: void |
| get_files() X-Ref |
| Returns the array of attached files. return: \stored_file[] |
| set($fieldname, $value) X-Ref |
| Setter. Basic checkings to prevent common issues. If the field is a string tags will be stripped, if it is an integer or a date it will be casted to a PHP integer. tdate fields values are expected to be timestamps. param: string $fieldname The field name param: string|int $value The value to store return: string|int The stored value |
| set_extra($fieldname, $value) X-Ref |
| Sets data to this->extradata This data can be retrieved using \core_search\document->get($fieldname). param: string $fieldname param: string $value return: void |
| get($field) X-Ref |
| Getter. Use self::is_set if you are not sure if this field is set or not as otherwise it will trigger a \coding_exception param: string $field return: string|int |
| is_set($field) X-Ref |
| Checks if a field is set. param: string $field return: bool |
| set_is_new($new) X-Ref |
| Set if this is a new document. False if unknown. param: bool $new |
| get_is_new() X-Ref |
| Returns if the document is new. False if unknown. return: bool |
| get_default_fields_definition() X-Ref |
| Returns all default fields definitions. return: array |
| format_time_for_engine($timestamp) X-Ref |
| Formats the timestamp preparing the time fields to be inserted into the search engine. By default it just returns a timestamp so any search engine could just store integers and use integers comparison to get documents between x and y timestamps, but search engines might be interested in using their own field formats. They can do it extending this class in \search_xxx\document. param: int $timestamp return: string |
| format_string_for_engine($string) X-Ref |
| Formats a string value for the search engine. Search engines may overwrite this method to apply restrictions, like limiting the size. The default behaviour is just returning the string. param: string $string return: string |
| format_text_for_engine($text) X-Ref |
| Formats a text value for the search engine. Search engines may overwrite this method to apply restrictions, like limiting the size. The default behaviour is just returning the string. param: string $text return: string |
| import_time_from_engine($time) X-Ref |
| Returns a timestamp from the value stored in the search engine. By default it just returns a timestamp so any search engine could just store integers and use integers comparison to get documents between x and y timestamps, but search engines might be interested in using their own field formats. They should do it extending this class in \search_xxx\document. param: string $time return: int |
| get_text_format() X-Ref |
| Returns how text is returned from the search engine. return: int |
| set_data_from_engine($docdata) X-Ref |
| Fills the document with data coming from the search engine. param: array $docdata return: void |
| set_doc_url(\moodle_url $url) X-Ref |
| Sets the document url. param: \moodle_url $url return: void |
| get_doc_url() X-Ref |
| Gets the url to the doc. return: \moodle_url |
| set_doc_icon(document_icon $docicon) X-Ref |
| Sets document icon instance. param: \core_search\document_icon $docicon |
| get_doc_icon() X-Ref |
| Gets document icon instance. return: \core_search\document_icon |
| set_context_url(\moodle_url $url) X-Ref |
| No description |
| get_context_url() X-Ref |
| Gets the url to the context. return: \moodle_url |
| export_for_engine() X-Ref |
| Returns the document ready to submit to the search engine. return: array |
| apply_defaults() X-Ref |
| Apply any defaults to unset fields before export. Called after document building, but before export. Sub-classes of this should make sure to call parent::apply_defaults(). |
| export_for_template(\renderer_base $output) X-Ref |
| Export the document data to be used as a template context. Adding more info than the required one as people might be interested in extending the template. Although content is a required field when setting up the document, it accepts '' (empty) values as they may be the result of striping out HTML. SECURITY NOTE: It is the responsibility of the document to properly escape any text to be displayed. The renderer will output the content without any further cleaning. param: renderer_base $output The renderer. return: array |
| format_text($text) X-Ref |
| Formats a text string coming from the search engine. By default just return the text as it is: - Search areas are responsible of sending just plain data, the search engine may append HTML or markdown to it (highlighing for example). - The view is responsible of shortening the text if it is too big param: string $text Text to format return: string HTML text to be renderer |
