Interface ActivityAdminSession

All Superinterfaces:

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

All Known Subinterfaces:

ActivityBatchAdminSession

public interface ActivityAdminSession
extends OsidSession

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

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

The delete operations delete Activities. To unmap an Activity from the current ObjectiveBank, the ActivityObjectiveBankAssignmentSession should be used. These delete operations attempt to remove the Activity itself thus removing it from all known ObjectiveBank catalogs.

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

Method Detail

getObjectiveBankId

Id getObjectiveBankId()

Gets the ObjectiveBank Id associated with this session.

Returns:

the ObjectiveBank Id associated with this session

Compliance:

mandatory - This method must be implemented.

getObjectiveBank

ObjectiveBank getObjectiveBank()
                               throws OperationFailedException,
                                      PermissionDeniedException

Gets the ObjectiveBank associated with this session.

Returns:

the ObjectiveBank associated with this session

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

Compliance:

mandatory - This method must be implemented.

canCreateActivities

boolean canCreateActivities()

Tests if this user can create Activities. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating an Activity 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.

Returns:

false if Activity creation is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

canCreateActivityWithRecordTypes

boolean canCreateActivityWithRecordTypes(Type[] activityRecordTypes)

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

Parameters:

activityRecordTypes - array of activity record types

Returns:

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

Throws:

NullArgumentException - activityRecordTypes is null

Compliance:

mandatory - This method must be implemented.

getActivityFormForCreate

ActivityForm getActivityFormForCreate(Id objectiveId,
                                    Type[] activityRecordTypes)
                                      throws NotFoundException,
                                             OperationFailedException,
                                             PermissionDeniedException

Gets the activity form for creating new activities. A new form should be requested for each create transaction.

Parameters:

objectiveId - the Id of the Objective

activityRecordTypes - array of activity record types

Returns:

the activity form

Throws:

NotFoundException - objectiveId is not found

NullArgumentException - objectiveId or activityRecordTypes is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure

UnsupportedException - unable to get form for requested record types

Compliance:

mandatory - This method must be implemented.

createActivity

Activity createActivity(ActivityForm activityForm)
                        throws OperationFailedException,
                               PermissionDeniedException

Creates a new Activity.

Parameters:

activityForm - the form for this Activity

Returns:

the new Activity

Throws:

IllegalStateException - activityForm already used in a create transaction
