| get_tool_proxy() X-Ref |
| Get the tool proxy object. return: stdClass |
| set_tool_proxy($toolproxy) X-Ref |
| Set the tool proxy object. param: object $toolproxy The tool proxy for this service request |
| get_type() X-Ref |
| Get the type object. return: stdClass |
| set_type($type) X-Ref |
| Set the LTI type object. param: object $type The LTI type for this service request |
| get_typeconfig() X-Ref |
| Get the type config array. return: array|null |
| set_typeconfig($typeconfig) X-Ref |
| Set the LTI type config object. param: array $typeconfig The LTI type config for this service request |
| get_permitted_scopes() X-Ref |
| Get the scope(s) permitted for this service in the context of a particular tool type. A null value indicates that no scopes are required to access the service. return: array|null |
| get_scopes() X-Ref |
| Get the scope(s) permitted for this service. A null value indicates that no scopes are required to access the service. return: array|null |
| get_configuration_options(&$mform) X-Ref |
| Returns the configuration options for this service. param: \MoodleQuickForm $mform Moodle quickform object definition |
| instance_added(object $lti) X-Ref |
| Called when a new LTI Instance is added. param: object $lti LTI Instance. |
| instance_updated(object $lti) X-Ref |
| Called when a new LTI Instance is updated. param: object $lti LTI Instance. |
| override_endpoint(string $messagetype, string $targetlinkuri,?string $customstr, int $courseid, ?object $lti = null) X-Ref |
| Called when the launch data is created, offering a possibility to alter the target link URI. param: string $messagetype message type for this launch param: string $targetlinkuri current target link uri param: null|string $customstr concatenated list of custom parameters param: int $courseid param: null|object $lti LTI Instance. return: array containing the target link URL and the custom params string to use. |
| instance_deleted(int $id) X-Ref |

| get_configuration_parameter_names() X-Ref |
| Return an array with the names of the parameters that the service will be saving in the configuration return: array Names list of the parameters that the service will be saving in the configuration |
| is_used_in_context($typeid, $courseid) X-Ref |
| Default implementation will check for the existence of at least one mod_lti entry for that tool and context. It may be overridden if other inferences can be done. Ideally a Site Tool should be explicitly engaged with a course, the check on the presence of a link is a proxy to infer a Site Tool engagement until an explicit Site Tool - Course relationship exists. param: int $typeid The tool lti type id. param: int $courseid The course id. return: bool returns True if tool is used in context, false otherwise. |
| is_allowed_in_context($typeid, $courseid) X-Ref |
| Checks if there is a site tool or a course tool for this site. param: int $typeid The tool lti type id. param: int $courseid The course id. return: bool returns True if tool is allowed in context, false otherwise. |
| get_launch_parameters($messagetype, $courseid, $userid, $typeid, $modlti = null) X-Ref |
| Return an array of key/values to add to the launch parameters. param: string $messagetype 'basic-lti-launch-request' or 'ContentItemSelectionRequest'. param: string $courseid The course id. param: string $userid The user id. param: string $typeid The tool lti type id. param: string $modlti The id of the lti activity. return: array Key/value pairs to add as launch parameters. |
| get_jwt_claim_mappings() X-Ref |
| Return an array of key/claim mapping allowing LTI 1.1 custom parameters to be transformed to LTI 1.3 claims. return: array Key/value pairs of params to claim mapping. |
| get_service_path() X-Ref |
| Get the path for service requests. return: string |
| parse_value($value) X-Ref |
| Parse a string for custom substitution parameter variables supported by this service's resources. param: string $value Value to be parsed return: string |
| check_tool($typeid, $body = null, $scopes = null) X-Ref |
| Check that the request has been properly signed and is permitted. param: string $typeid LTI type ID param: string $body Request body (null if none) param: string[] $scopes Array of required scope(s) for incoming request return: boolean |
| check_tool_proxy($toolproxyguid, $body = null) X-Ref |
| Check that the request has been properly signed. param: string $toolproxyguid Tool Proxy GUID param: string $body Request body (null if none) return: boolean |
| check_type($typeid, $courseid, $body = null) X-Ref |
| Check that the request has been properly signed. param: int $typeid The tool id param: int $courseid The course we are at param: string $body Request body (null if none) return: bool |
