OSID - osid.subscription.rules.DispatchProcessorEnablerLookupSession Service Interface Definition

Interface	osid.subscription.rules.DispatchProcessorEnablerLookupSession
Implements	`osid.OsidSession`
Used By	`osid.subscription.rules.SubscriptionRulesManager`
Used By	`osid.subscription.rules.SubscriptionRulesProxyManager`
Description	This session provides methods for retrieving `DispatchProcessorEnablers` . 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 publisher view: All dispatch processor enabler methods in this session operate, retrieve and pertain to dispatch processor enablers defined explicitly in the current publisher Using an isolated view is useful for managing `DispatchProcessorEnablers` with the `DispatchProcessorEnablerAdminSession` . federated publisher view: All dispatch processor enabler methods in this session operate, retrieve and pertain to all dispatch processor enablers defined in this publisher and any other dispatch processor enablers implicitly available in this publisher through publisher 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 `useFederatedPublisherView()` and `useIsolatedPublisherView() beha` ve as a radio group and one should be selected before invoking any lookup methods.
Method	getPublisherId
Description	Gets the `Publisher` `Id` associated with this session.
Return	`osid.id.Id`		the `Publisher Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getPublisher
Description	Gets the `Publisher` associated with this session.
Return	`osid.subscription.Publisher`		the publisher
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canLookupDispatchProcessorEnablers
Description	Tests if this user can perform `DispatchProcessorEnabler` 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	useComparativeDispatchProcessorEnablerView
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	usePlenaryDispatchProcessorEnablerView
Description	A complete view of the `DispatchProcessorEnabler` 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	useFederatedPublisherView
Description	Federates the view for methods in this session. A federated view will include dispatch processor enablers in publishers which are children of this publisher in the publisher hierarchy.
Compliance	`mandatory`		This method is must be implemented.
Method	useIsolatedPublisherView
Description	Isolates the view for methods in this session. An isolated view restricts lookups to this publisher only.
Compliance	`mandatory`		This method is must be implemented.
Method	getDispatchProcessorEnabler
Description	Gets the `DispatchProcessorEnabler` specified by its `Id` . In plenary mode, the exact `Id` is found or a `NOT_FOUND` results. Otherwise, the returned `DispatchProcessorEnabler` may have a different `Id` than requested, such as the case where a duplicate `Id` was assigned to a `DispatchProcessorEnabler and r` etained for compatibility.
Parameters	`osid.id.Id`	`dispatchProcessorEnablerId`	`Id` of the `DispatchProcessorEnabler`
Return	`osid.subscription.rules.DispatchProcessorEnabler`		the dispatch processor enabler
Errors	NOT_FOUND		`dispatchProcessorEnablerId` not found
	NULL_ARGUMENT		`dispatchProcessorEnablerId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method is must be implemented.
Method	getDispatchProcessorEnablersByIds
Description	Gets a `DispatchProcessorEnablerList` corresponding to the given `IdList` . In plenary mode, the returned list contains all of the dispatch processor 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 `DispatchProcessorEnablers may be` omitted from the list and may present the elements in any order including returning a unique set.
Parameters	`osid.id.IdList`	`dispatchProcessorEnablerIds`	the list of `Ids` to retrieve
Return	`osid.subscription.rules.DispatchProcessorEnablerList`		the returned `DispatchProcessorEnabler` list
Errors	NOT_FOUND		an `Id was` not found
	NULL_ARGUMENT		`dispatchProcessorEnablerIds` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getDispatchProcessorEnablersByGenusType
Description	Gets a `DispatchProcessorEnablerList` corresponding to the given dispatch processor enabler genus `Type` which does not include dispatch processor enablers of genus types derived from the specified `Type` . In plenary mode, the returned list contains all known dispatch processor enablers or an error results. Otherwise, the returned list may contain only those dispatch processor enablers that are accessible through this session.
Parameters	`osid.type.Type`	`dispatchProcessorEnablerGenusType`	a dispatch processor enabler genus type
Return	`osid.subscription.rules.DispatchProcessorEnablerList`		the returned `DispatchProcessorEnabler` list
Errors	NULL_ARGUMENT		`dispatchProcessorEnablerGenusType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getDispatchProcessorEnablersByParentGenusType
Description	Gets a `DispatchProcessorEnablerList` corresponding to the given dispatch processor enabler genus `Type` and include any additional dispatch processor enablers with genus types derived from the specified `Type` . In plenary mode, the returned list contains all known dispatch processor enablers or an error results. Otherwise, the returned list may contain only those dispatch processor enablers that are accessible through this session.
Parameters	`osid.type.Type`	`dispatchProcessorEnablerGenusType`	a dispatch processor genus type
