OSID - osid.learning.ObjectiveObjectiveBankAssignmentSession Service Interface Definition

Interface	osid.learning.ObjectiveObjectiveBankAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `Objectives` to `ObjectiveBanks.` An `Objective` may map to multiple `ObjectiveBanks` and removing the last reference to an `Objective` 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 `Objective` to another `ObjectiveBank` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignObjectives
Description	Tests if this user can alter objective/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	canAssignObjectivesToObjectiveBank
Description	Tests if this user can alter objective/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 objective 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	getAssignableObjectiveBankIdsForObjective
Description	Gets a list of objective banks including and under the given objective bank node in which a specific objective can be assigned.
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Parameters	`osid.id.Id`	`objectiveId`	the `Id` of the `Objective`
Return	`osid.id.IdList`		list of assignable objective bank `Ids`
Errors	NULL_ARGUMENT		`objectiveId` or `objectiveBankId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignObjectiveToObjectiveBank
Description	Adds an existing `Objective` to an `ObjectiveBank.`
Parameters	`osid.id.Id`	`objectiveId`	the `Id` of the `Objective`
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Errors	ALREADY_EXISTS		`objectiveId` already mapped to `objectiveBankId`
	NOT_FOUND		`objectiveId` or `objectiveBankId` not found
	NULL_ARGUMENT		`objectiveId` or `objectiveBankId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignObjectiveFromObjectiveBank
Description	Removes an `Objective` from an `ObjectiveBank.`
Parameters	`osid.id.Id`	`objectiveId`	the `Id` of the `Objective`
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Errors	NOT_FOUND		`objectiveId` or `objectiveBankId` not found or `objectiveId` not mapped to `objectiveBankId`
	NULL_ARGUMENT		`objectiveId` or `objectiveBankId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignProficiencyToObjectiveBank
Description	Moves an `Objective` from one `ObjectiveBank` to another. Mappings to other `ObjectiveBanks` are unaffected.
Parameters	`osid.id.Id`	`objectiveId`	the `Id` of the `Objective`
	`osid.id.Id`	`fromObjectiveBankId`	the `Id` of the current `ObjectiveBank`
	`osid.id.Id`	`toObjectiveBankId`	the `Id` of the destination `ObjectiveBank`
Errors	NOT_FOUND		`objectiveId, fromObjectiveBankId,` or `toObjectiveBankId` not found or `objectiveId` not mapped to `fromObjectiveBankId`
	NULL_ARGUMENT		`objectiveId, fromObjectiveBankId,` or `toObjectiveBankId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
