Interface EnrollmentAdminSession

All Superinterfaces:

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

All Known Subinterfaces:

EnrollmentBatchAdminSession

public interface EnrollmentAdminSession
extends OsidSession

This session creates, updates, and deletes Enrollments. 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 an Enrollment, an EnrollmentForm is requested using getEnrollmentFormFormForCreate() specifying the desired record Types or none if no record Types are needed. The returned EnrollmentForm 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 EnrollmentForm is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each EnrollmentForm corresponds to an attempted transaction.

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

The delete operations delete Enrollments. To unmap an EnrollmentForm from the current CourseCatalog, the EnrollmentCourseCatalogAssignmentSession should be used. These delete operations attempt to remove the EnrollmentForm 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.

                                      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.

canCreateEnrollments

boolean canCreateEnrollments()

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

Compliance:

mandatory - This method must be implemented.

canCreateEnrollmentWithRecordTypes

boolean canCreateEnrollmentWithRecordTypes(Type[] enrollmentRecordTypes)

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

Parameters:

enrollmentRecordTypes - array of enrollment record types

Returns:

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

Throws:

NullArgumentException - enrollmentRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getEnrollmentFormForCreate

                                        Id resourceId,
                                        Type[] enrollmentRecordTypes)
                                          throws NotFoundException,

the enrollment form

Throws:

NotFoundException - programOfferingId, or resourceId is not found

NullArgumentException - programOfferingId, resourceId, or enrollmentRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form for requested recod types

Compliance:
