OSID - osid.provisioning.rules.QueueEnablerLookupSession Service Interface Definition

Interface	osid.provisioning.rules.QueueEnablerLookupSession
Implements	`osid.OsidSession`
Used By	`osid.provisioning.rules.ProvisioningRulesManager`
Used By	`osid.provisioning.rules.ProvisioningRulesProxyManager`
Description	This session provides methods for retrieving `QueueEnablers`. This session defines views that offer differing behaviors when retrieving multiple objects. comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete set or is an error condition isolated distributor view: All queue enabler methods in this session operate, retrieve and pertain to queue enablers defined explicitly in the current distributor Using an isolated view is useful for managing `QueueEnablers` with the `QueueEnablerAdminSession`. federated distributor view: All queue enabler methods in this session operate, retrieve and pertain to all queue enablers defined in this distributor and any other queue enablers implicitly available in this distributor through distributor inheritence. Generally, the comparative view should be used for most applications as it permits operation even if there is data that cannot be accessed. The methods `useFederatedDistributorView()` and `useIsolatedDistributorView() be` have as a radio group and one should be selected before invoking any lookup methods.
Method	getDistributorId
Description	Gets the `Distributor` `Id` associated with this session.
Return	`osid.id.Id`		the `Distributor Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getDistributor
Description	Gets the `Distributor` associated with this session.
Return	`osid.provisioning.Distributor`		the distributor
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canLookupQueueEnablers
Description	Tests if this user can perform `QueueEnabler` lookups. A return of true does not guarantee successful authorization. A return of false indicates that it is known all 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 lookup methods are not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	useComparativeQueueEnablerView
Description	The returns from the lookup methods may omit or translate elements based on this session, such as authorization, and not result in an error. This view is used when greater interoperability is desired at the expense of precision.
Compliance	`mandatory`		This method is must be implemented.
Method	usePlenaryQueueEnablerView
Description	A complete view of the `QueueEnabler` returns is desired. Methods will return what is requested or result in an error. This view is used when greater precision is desired at the expense of interoperability.
Compliance	`mandatory`		This method is must be implemented.
Method	useFederatedDistributorView
Description	Federates the view for methods in this session. A federated view will include queue enablers in distributors which are children of this distributor in the distributor hierarchy.
Compliance	`mandatory`		This method is must be implemented.
Method	useIsolatedDistributorView
Description	Isolates the view for methods in this session. An isolated view restricts lookups to this distributor only.
Compliance	`mandatory`		This method is must be implemented.
Method	getQueueEnabler
Description	Gets the `QueueEnabler` specified by its `Id`. In plenary mode, the exact `Id` is found or a `NOT_FOUND` results. Otherwise, the returned `QueueEnabler` may have a different `Id` than requested, such as the case where a duplicate `Id` was assigned to a `QueueEnabler and reta` ined for compatibility.
Parameters	`osid.id.Id`	`queueEnablerId`	`Id` of the `QueueEnabler`
Return	`osid.provisioning.rules.QueueEnabler`		the queue enabler
Errors	NOT_FOUND		`queueEnablerId` not found
	NULL_ARGUMENT		`queueEnablerId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method is must be implemented.
Method	getQueueEnablersByIds
Description	Gets a `QueueEnablerList` corresponding to the given `IdList`. In plenary mode, the returned list contains all of the queue enablers specified in the `Id` list, in the order of the list, including duplicates, or an error results if an `Id` in the supplied list is not found or inaccessible. Otherwise, inaccessible `QueueEnablers may be om` itted from the list and may present the elements in any order including returning a unique set.
Parameters	`osid.id.IdList`	`queueEnablerIds`	the list of `Ids` to retrieve
Return	`osid.provisioning.rules.QueueEnablerList`		the returned `QueueEnabler` list
Errors	NOT_FOUND		an `Id was` not found
	NULL_ARGUMENT		`queueEnablerIds` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getQueueEnablersByGenusType
Description	Gets a `QueueEnablerList` corresponding to the given queue enabler genus `Type` which does not include queue enablers of genus types derived from the specified `Type`. In plenary mode, the returned list contains all known queue enablers or an error results. Otherwise, the returned list may contain only those queue enablers that are accessible through this session.
Parameters	`osid.type.Type`	`queueEnablerGenusType`	a queue enabler genus type
Return	`osid.provisioning.rules.QueueEnablerList`		the returned `QueueEnabler` list
Errors	NULL_ARGUMENT		`queueEnablerGenusType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getQueueEnablersByParentGenusType
Description	Gets a `QueueEnablerList` corresponding to the given queue enabler genus `Type` and include any additional queue enablers with genus types derived from the specified `Type`. In plenary mode, the returned list contains all known queue enablers or an error results. Otherwise, the returned list may contain only those queue enablers that are accessible through this session.
Parameters	`osid.type.Type`	`queueEnablerGenusType`	a queue genus type
Return	`osid.provisioning.rules.QueueEnablerList`		the returned `QueueEnabler` list
Errors	NULL_ARGUMENT		`queueEnablerGenusType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getQueueEnablersByRecordType
Description	Gets a `QueueEnablerList` containing the given queue enabler record `Type`. In plenary mode, the returned list contains all known queue enablers or an error results. Otherwise, the returned list may contain only those queue enablers that are accessible through this session.
Parameters	`osid.type.Type`	`queueEnablerRecordType`	a queue enabler record type
Return	`osid.provisioning.rules.QueueEnablerList`		the returned `QueueEnabler` list
Errors	NULL_ARGUMENT		`queueEnablerRecordType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getQueueEnablers
Description	Gets all `QueueEnablers`. In plenary mode, the returned list contains all known queue enablers or an error results. Otherwise, the returned list may contain only those queue enablers that are accessible through this session.
Return	`osid.provisioning.rules.QueueEnablerList`		a list of `QueueEnablers`
