OSID - osid.tracking.rules.QueueConstrainerFrontOfficeAssignmentSession Service Interface Definition

Interface	osid.tracking.rules.QueueConstrainerFrontOfficeAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.tracking.rules.TrackingRulesManager`
Used By	`osid.tracking.rules.TrackingRulesProxyManager`
Description	This session provides methods to re-assign `QueueConstrainer` to `FrontOffice` mappings. a `QueueConstrainer` may appear in multiple `FrontOffice` objects and removing the last reference to a `QueueConstrainer` is the equivalent of deleting it. Each `FrontOffice` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `QueueConstrainer` to another `FrontOffice` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignQueueConstrainers
Description	Tests if this user can alter queue constrainer/office 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 lookup operations to unauthorized users.
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canAssignQueueConstrainersToFrontOffice
Description	Tests if this user can alter queue constrainer/office 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 lookup operations to unauthorized users.
Parameters	`osid.id.Id`	`frontOfficeId`	the `Id` of the `FrontOffice`
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`frontOfficeId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableFrontOfficeIds
Description	Gets a list of front office including and under the given front office node in which any queue constrainer can be assigned.
Parameters	`osid.id.Id`	`frontOfficeId`	the `Id` of the `FrontOffice`
Return	`osid.id.IdList`		list of assignable front office `Ids`
Errors	NULL_ARGUMENT		`frontOfficeId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableFrontOfficeIdsForQueueConstrainer
Description	Gets a list of front office including and under the given front office node in which a specific queue constrainer can be assigned.
Parameters	`osid.id.Id`	`frontOfficeId`	the `Id` of the `FrontOffice`
Parameters	`osid.id.Id`	`queueConstrainerId`	the `Id` of the `QueueConstrainer`
Return	`osid.id.IdList`		list of assignable front office `Ids`
Errors	NULL_ARGUMENT		`frontOfficeId` or `queueConstrainerId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignQueueConstrainerToFrontOffice
Description	Adds an existing `QueueConstrainer` to a `FrontFront Office` .
Parameters	`osid.id.Id`	`queueConstrainerId`	the `Id` of the `QueueConstrainer`
Parameters	`osid.id.Id`	`frontOfficeId`	the `Id` of the `FrontOffice`
Errors	ALREADY_EXISTS		`queueConstrainerId` is already assigned to `frontOfficeId`
	NOT_FOUND		`queueConstrainerId` or `frontOfficeId` not found
	NULL_ARGUMENT		`queueConstrainerId` or `frontOfficeId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignQueueConstrainerFromFrontOffice
Description	Removes a `QueueConstrainer` from a `FrontFront Office` .
Parameters	`osid.id.Id`	`queueConstrainerId`	the `Id` of the `QueueConstrainer`
Parameters	`osid.id.Id`	`frontOfficeId`	the `Id` of the `FrontOffice`
Errors	NOT_FOUND		`queueConstrainerId` or `frontOfficeId` not found or `queueConstrainerId` not assigned to `frontOfficeId`

Compliance	`mandatory`		This method must be implemented.
Method	reassignQueueConstrainerToFrontOffice
Description	Moves a `QueueConstrainer` from one `FrontOffice` to another. Mappings to other `FrontOffices` are unaffected.
