OSID - osid.hold.IssueOublietteAssignmentSession Service Interface Definition

Interface	osid.hold.IssueOublietteAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `Issues` to `Oubliette` mappings. An `Issue` may appear in multiple `Oubliette` objects and removing the last reference to an `Issue` is the equivalent of deleting it. Each `Oubliette` may have its own authorizations governing who is allowed to operate on it. Adding a reference of an `Issue` to another `Oubliette` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignIssues
Description	Tests if this user can alter issue/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 issue is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canAssignIssuesToOubliette
Description	Tests if this user can alter issue/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 issue can be assigned.
Parameters	`osid.id.Id`	`oublietteId`	the `Id` of the `Oubliette`
Return	`osid.id.IdList`		list of assignable oubliette `Ids`
Errors	NULL_ARGUMENT		`oublietteId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableOublietteIdsForIssue
Description	Gets a list of oubliettes including and under the given oubliette node in which a specific issue can be assigned.
Parameters	`osid.id.Id`	`oublietteId`	the `Id` of the `Oubliette`
Parameters	`osid.id.Id`	`issueId`	the `Id` of the `Issue`
Return	`osid.id.IdList`		list of assignable oubliette `Ids`
Errors	NULL_ARGUMENT		`oublietteId` or `issueId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignIssueToOubliette
Description	Adds an existing `Issue` to a `Oubliette.`
Parameters	`osid.id.Id`	`issueId`	the `Id` of the `Issue`
Parameters	`osid.id.Id`	`oublietteId`	the `Id` of the `Oubliette`
Errors	ALREADY_EXISTS		`issueId` is already assigned to `oublietteId`
	NOT_FOUND		`issueId` or `oublietteId` not found
	NULL_ARGUMENT		`issueId` or `oublietteId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignIssueFromOubliette
Description	Removes an `Issue` from a `Oubliette.`
Parameters	`osid.id.Id`	`issueId`	the `Id` of the `Issue`
Parameters	`osid.id.Id`	`oublietteId`	the `Id` of the `Oubliette`
Errors	NOT_FOUND		`issueId` or `oublietteId` not found or `issueId` is not assigned to `oublietteId`
	NULL_ARGUMENT		`issueId` or `oublietteId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignIssueToOubliette
Description	Moves an `Issue` from one `Oubliette` to another. Mappings to other `Oubliettes` are unaffected.
Parameters	`osid.id.Id`	`issueId`	the `Id` of the `Issue`
	`osid.id.Id`	`fromOublietteId`	the `Id` of the current `Oubliette`
	`osid.id.Id`	`toOublietteId`	the `Id` of the destination `Oubliette`
Errors	NOT_FOUND		`issueId, fromOublietteId,` or `toOublietteId` not found or `issueId` not mapped to `fromOublietteId`
	NULL_ARGUMENT		`issueId, fromOublietteId,` or `toOublietteId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
