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

Interface	osid.hold.rules.IssueConstrainerEnablerOublietteAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.hold.rules.HoldRulesManager`
Used By	`osid.hold.rules.HoldRulesProxyManager`
Description	This session provides methods to re-assign `IssueConstrainerEnabler` to `Oubliette` mappings. An `IssueConstrainerEnabler` may appear in multiple `Oubliette` catalogs and removing the last reference to an `IssueConstrainerEnabler` 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 `IssueConstrainerEnabler` to another `Oubliette is n` ot a copy operation (eg: does not change its `Id`).
Method	canAssignIssueConstrainerEnablers
Description	Tests if this user can alter issue constrainer 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. T` his 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	canAssignIssueConstrainerEnablerToOubliette

Method	getAssignableOublietteIds
Description	Gets a list of oubliettes including and under the given oubliette node in which any issue constrainer enabler can be assigned.
Parameters	`osid.id.Id`	`oublietteId`	the `Id` of the `Oubliette`
Return	`osid.id.IdList`		list of assignable oubliette `Ids`

Parameters	`osid.id.Id`	`issueConstrainerEnablerId`	the `Id` of the `IssueConstrainerEnabler`
Return	`osid.id.IdList`		list of assignable oubliette `Ids`
Errors	NULL_ARGUMENT		`oublietteId` or `issueConstrainerEnablerId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignIssueConstrainerEnablerToOubliette
Description	Adds an existing `IssueConstrainerEnabler` to an `Oubliette`.
Parameters	`osid.id.Id`	`issueConstrainerEnablerId`	the `Id` of the `IssueConstrainerEnabler`
Parameters	`osid.id.Id`	`oublietteId`	the `Id` of the `Oubliette`
Errors	ALREADY_EXISTS		`issueConstrainerEnablerId` is already assigned to `oublietteId`
	NOT_FOUND		`issueConstrainerEnablerId` or `oublietteId` not found
	NULL_ARGUMENT		`issueConstrainerEnablerId` or `oublietteId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignIssueConstrainerEnablerFromOubliette
Description	Removes an `IssueConstrainerEnabler` from an `Oubliette`.
