This is an example subset of the Learning OSID where two of the OsidSessions manage retrieval and querying of learning objectives.
| Method | supportsObjectiveLookup | ||
|---|---|---|---|
| Description | Tests if an objective lookup service is supported. An objective lookup service defines methods to access objectives. | ||
| Return | boolean | true if objective lookup is supported, false otherwise | |
| Compliance | mandatory | This method must be implemented. | |
| Method | getObjectiveLookupSession | ||
| Description | Gets the OsidSession associated with the objective lookup service. | ||
| Return | osid.learning.ObjectiveLookupSession | an ObjectiveLookupSession | |
Errors | OPERATION_FAILED | unable to complete request | |
| UNIMPLEMENTED | supportsObjectiveLookup() is false | ||
| Compliance | optional | This method must be implemented if supportsObjectiveLookup() is true. | |
Method | supportsObjectiveQuery | ||
| Description | Tests if an objective query service is supported. | ||
| Return | boolean | true if objective query is supported, false otherwise | |
| Compliance | mandatory | This method must be implemented. | |
| Method | getObjectiveQuerySession | ||
| Description | Gets the OsidSession associated with the objective query service. | ||
| Return | osid.learning.ObjectiveQuerySession | an ObjectiveQuerySession | |
| Errors | OPERATION_FAILED | unable to complete request | |
| UNIMPLEMENTED | supportsObjectiveQuery() is false | ||
| Compliance | optional | This method must be implemented if supportsObjectiveQuery() is true. | |
