OSID - osid.learning.ActivityObjectiveBankAssignmentSession Service Interface Definition

Interface	osid.learning.ActivityObjectiveBankAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.learning.LearningManager`
Used By	`osid.learning.LearningProxyManager`
Description	This session provides methods to re-assign `Activities` to `ObjectiveBanks`. An `Activity` may map to multiple `ObjectiveBanks` and removing the last reference to a `Activity` is the equivalent of deleting it. Each `ObjectiveBank` may have its own authorizations governing who is allowed to operate on it. Moving or adding a reference of an `Activity` to another `ObjectiveBank` is not a copy operation (eg: does not change its `Id`).
Method	canAssignActivities
Description	Tests if this user can alter activity/objective bank mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known mapping methods in this session will result in a `PERMISSION_DENIED`. This is intended as a hint to an application that may opt not to offer assignment operations to unauthorized users.
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canAssignActivitiesToObjectiveBank
Description	Tests if this user can alter activity/objective bank mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known mapping methods in this session will result in a `PERMISSION_DENIED`. This is intended as a hint to an application that may opt not to offer assignment operations to unauthorized users.
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`objectiveBankId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableObjectiveBankIds
Description	Gets a list of objective banks including and under the given objective bank node in which any activity can be assigned.
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Return	`osid.id.IdList`		list of assignable objective bank `Ids`
Errors	NULL_ARGUMENT		`objectiveBankId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableObjectiveBankIdsForActivity
Description	Gets a list of objective banks including and under the given objective bank node in which a specific activity can be assigned.
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Parameters	`osid.id.Id`	`activityId`	the `Id` of the `Activity`
Return	`osid.id.IdList`		list of assignable objective bank `Ids`
Errors	NULL_ARGUMENT		`activityId` or `objectiveBankId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignActivityToObjectiveBank
Description	Adds an existing `Activity` to a `ObjectiveBank`.
Parameters	`osid.id.Id`	`activityId`	the `Id` of the `Activity`
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Errors	ALREADY_EXISTS		`activityId` already mapped to `objectiveBankId`
	NOT_FOUND		`activityId` or `objectiveBankId` not found
	NULL_ARGUMENT		`activityId` or `objectiveBankId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignActivityFromObjectiveBank
Description	Removes a `Activity` from a `ObjectiveBank`.
Parameters	`osid.id.Id`	`activityId`	the `Id` of the `Activity`
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Errors	NOT_FOUND		`activityId` or `objectiveBankId` not found or `activityId` not mapped to `objectiveBankId`
	NULL_ARGUMENT		`activityId` or `objectiveBankId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignActivityToObjectiveBank
Description	Moves an `Activity` from one `ObjectiveBank` to another. Mappings to other `ObjectiveBanks` are unaffected.
Parameters	`osid.id.Id`	`activityId`	the `Id` of the `Activity`
	`osid.id.Id`	`fromObjectiveBankId`	the `Id` of the current `ObjectiveBank`
	`osid.id.Id`	`toObjectiveBankId`	the `Id` of the destination `ObjectiveBank`
Errors	ALREADY_EXISTS		`activityId` already assigned to `toObjectiveBankId`
	NOT_FOUND		`activityId, fromObjectiveBankId`, or `toObjectiveBankId` not found or `activityId` not mapped to `fromObjectiveBankId`
	NULL_ARGUMENT		`activityId, fromObjectiveBankId`, or `toObjectiveBankId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
