OSID - osid.hold.rules.HoldEnablerOublietteAssignmentSession Service Interface Definition

Interface	osid.hold.rules.HoldEnablerOublietteAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.hold.rules.HoldRulesManager`
Used By	`osid.hold.rules.HoldRulesProxyManager`
Description	This session provides methods to re-assign `HoldEnabler` to `Oubliette` mappings. A `HoldEnabler` may appear in multiple `Oubliette` objects and removing the last reference to a `HoldEnabler` is the equivalent of deleting it. Each `Hold` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `HoldEnabler` to another `Oubliette` is not a copy operation (eg: does not change its `Id`).
Method	canAssignHoldEnablers
Description	Tests if this user can alter hold enabler/oubliette 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	canAssignHoldEnablersToOubliette
Description	Tests if this user can alter hold enabler/oubliette 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`	`oublietteId`	the `Id` of the `Oubliette`
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`oublietteId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableOublietteIds
Description	Gets a list of oubliettes including and under the given oubliette node in which any oubliette enabler can be assigned.
Parameters	`osid.id.Id`	`oublietteId`	the `Id` of the `Oubliette`
Return	`osid.id.IdList`		list of assignable hold `Ids`
Errors	NULL_ARGUMENT		`oublietteId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableOublietteIdsForHoldEnabler
Description	Gets a list of oubliettes including and under the given oubliette node in which a specific oubliette enabler can be assigned.
Parameters	`osid.id.Id`	`oublietteId`	the `Id` of the `Oubliette`
Parameters	`osid.id.Id`	`holdEnablerId`	the `Id` of the `HoldEnabler`
Return	`osid.id.IdList`		list of assignable oubliette `Ids`
Errors	NULL_ARGUMENT		`oublietteId` or `holdEnablerId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignHoldEnablerToOubliette
Description	Adds an existing `HoldEnabler` to a `Oubliette`.
Parameters	`osid.id.Id`	`holdEnablerId`	the `Id` of the `HoldEnabler`
Parameters	`osid.id.Id`	`oublietteId`	the `Id` of the `Oubliette`
Errors	ALREADY_EXISTS		`holdEnablerId` is already assigned to `oublietteId`
	NOT_FOUND		`holdEnablerId` or `oublietteId` not found
	NULL_ARGUMENT		`holdEnablerId` or `oublietteId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignHoldEnablerFromOubliette
Description	Removes a `HoldEnabler` from a `Oubliette`.
Parameters	`osid.id.Id`	`holdEnablerId`	the `Id` of the `HoldEnabler`
Parameters	`osid.id.Id`	`oublietteId`	the `Id` of the `Oubliette`
Errors	NOT_FOUND		`holdEnablerId` or `oublietteId` not found or `holdEnablerId` is not assigned to `oublietteId`
	NULL_ARGUMENT		`holdEnablerId` or `oublietteId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignHoldEnablerToOubliette
Description	Moves a `HoldEnabler` from one `Oubliette` to another. Mappings to other `Oubliettes` are unaffected.
Parameters	`osid.id.Id`	`holdEnablerId`	the `Id` of the `HoldEnabelr`
	`osid.id.Id`	`fromOublietteId`	the `Id` of the current `Oubliette`
	`osid.id.Id`	`toOublietteId`	the `Id` of the destination `Oubliette`
Errors	ALREADY_EXISTS		`holdEnablerId` already assigned to `toOublietteId`
	NOT_FOUND		`holdEnabler, fromOublietteId`, or `toOublietteId` not found or `holdEnablerId` not mapped to `fromOublietteId`
	NULL_ARGUMENT		`holdEnablerId, fromOublietteId`, or `toOublietteId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
