Interface LessonAdminSession

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidSession

public interface LessonAdminSession
extends OsidSession

This session creates, updates, and deletes Lessons. The data for create and update is provided by the consumer via the form object. OsidForms are requested for each create or update and may not be reused.

Create and update operations differ in their usage. To create a Lesson, a LessonForm is requested using getLessonFormForCreate() specifying the desired record Types or none if no record Types are needed. The returned LessonForm will indicate that it is to be used with a create operation and can be used to examine metdata or validate data prior to creation. Once the LessonForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each LessonForm corresponds to an attempted transaction.

For updates, LessonForms are requested to the Lesson Id that is to be updated using getLessonForUpdate(). Similarly, the LessonForm has metadata about the data that can be updated and it can perform validation before submitting the update. The LessonForm can only be used once for a successful update and cannot be reused.

The delete operations delete Lessons. To unmap a Lesson from the current CourseCatalog, the LessonCourseCatalogAssignmentSession should be used. These delete operations attempt to remove the Lesson itself thus removing it from all known CourseCatalog catalogs.

This session includes an Id aliasing mechanism to assign an external Id to an internally assigned Id.

Method Detail

getCourseCatalogId

Id getCourseCatalogId()

Gets the CourseCatalog Id associated with this session.

Returns:

the CourseCatalog Id associated with this session

Compliance:

mandatory - This method must be implemented.

getCourseCatalog

CourseCatalog getCourseCatalog()
                               throws OperationFailedException,
                                      PermissionDeniedException

Gets the CourseCatalog associated with this session.

Returns:

the course catalog

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canCreateLessons

boolean canCreateLessons()

Tests if this user can create Lessons. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a Lesson will result in a PERMISSION_DENIED. This is intended as a hint to an application that may not wish to offer create operations to unauthorized users.

Returns:

false if Lesson creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateLessonWithRecordTypes

boolean canCreateLessonWithRecordTypes(Type[] lessonRecordTypes)

Tests if this user can create a single Lesson using the desired record types. While CoursePlanManager.getLessonRecordTypes() can be used to examine which records are supported, this method tests which record(s) are required for creating a specific Lesson. Providing an empty array tests if a Lesson can be created with no records.

Parameters:

lessonRecordTypes - array of lesson record types

Returns:

true if Lesson creation using the specified record Types is supported, false otherwise

Throws:

NullArgumentException - lessonRecordTypes is null

Compliance:

mandatory - This method must be implemented.

                                  throws NotFoundException,

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form for requested record types

Compliance:

mandatory - This method must be implemented.
