OSID - osid.learning.ProficiencyObjectiveBankAssignmentSession Service Interface Definition

Interface	osid.learning.ProficiencyObjectiveBankAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `Proficiencies` to `ObjectiveBank` objects. A `Proficiency` may appear in multiple `ObjectiveBank` objects and removing the last reference to a `Proficiency` is the equivalent of deleting it. Each `ObjectiveBank` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `Proficiency` to another `ObjectiveBank` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignProficiencies
Description	Tests if this user can alter proficiency/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	canAssignProficienciesToObjectiveBank
Description	Tests if this user can alter proficiency/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 proficiency in which any proficiency can be assigned.
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Return	`osid.id.IdList`		list of assignable objectiveBank `Ids`
Errors	NULL_ARGUMENT		`objectiveBankId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableObjectiveBankIdsForProficiency
Description	Gets a list of objective banks including and under the given objective bank proficiency in which a specific proficiency can be assigned.
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Parameters	`osid.id.Id`	`proficiencyId`	the `Id` of the `Proficiency`
Return	`osid.id.IdList`		list of assignable objectiveBank `Ids`
Errors	NULL_ARGUMENT		`objectiveBankId` or `proficiencyId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignProficiencyToObjectiveBank
Description	Adds an existing `Proficiency` to a `ObjectiveBank.`
Parameters	`osid.id.Id`	`proficiencyId`	the `Id` of the `Proficiency`
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Errors	ALREADY_EXISTS		`proficiencyId` is already mapped to `objectiveBankId`
	NOT_FOUND		`proficiencyId` or `objectiveBankId` not found
	NULL_ARGUMENT		`proficiencyId` or `objectiveBankId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignProficiencyFromObjectiveBank
Description	Removes a `Proficiency` from a `ObjectiveBank.`
Parameters	`osid.id.Id`	`proficiencyId`	the `Id` of the `Proficiency`
Parameters	`osid.id.Id`	`objectiveBankId`	the `Id` of the `ObjectiveBank`
Errors	NOT_FOUND		`proficiencyId` or `objectiveBankId` not found or `proficiencyId` not mapped to `objectiveBankId`
	NULL_ARGUMENT		`proficiencyId` 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 a `Proficiency` from one `ObjectiveBank` to another. Mappings to other `ObjectiveBanks` are unaffected.
Parameters	`osid.id.Id`	`proficiencyId`	the `Id` of the `Proficiency`
	`osid.id.Id`	`fromObjectiveBankId`	the `Id` of the current `ObjectiveBank`
	`osid.id.Id`	`toObjectiveBankId`	the `Id` of the destination `ObjectiveBank`
Errors	NOT_FOUND		`proficiencyId, fromObjectiveBankId,` or `toObjectiveBankId` not found or `proficiencyId` not mapped to `fromObjectiveBankId`
	NULL_ARGUMENT		`proficiencyId, fromObjectiveBankId,` or `toObjectiveBankId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
