OSID - osid.ordering.rules.PriceEnablerLookupSession Service Interface Definition

Interface	osid.ordering.rules.PriceEnablerLookupSession
Implements	`osid.OsidSession`
Used By	`osid.ordering.rules.OrderingRulesManager`
Used By	`osid.ordering.rules.OrderingRulesProxyManager`
Description	This session provides methods for retrieving `PriceEnablers`. 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 store view: All price enabler methods in this session operate, retrieve and pertain to price enablers defined explicitly in the current store. Using an isolated view is useful for managing `PriceEnablers` with the `PriceEnablerAdminSession`. federated store view: All price enabler methods in this session operate, retrieve and pertain to all price enablers defined in this store and any other price enablers implicitly available in this store through store 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()` behave as a radio group and one should be selected before invoking the methods in this session.
Method	getStoreId
Description	Gets the `Store` `Id` associated with this session.
Return	`osid.id.Id`		the `Store Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getStore
Description	Gets the `Store` associated with this session.
Return	`osid.ordering.Store`		the store
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canLookupPriceEnablers
Description	Tests if this user can perform `PriceEnablers` 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	useComparativePriceEnablerView
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	usePlenaryPriceEnablerView
Description	A complete view of the `PriceEnabler` 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	useFederatedStoreView
Description	Federates the view for methods in this session. A federated view will include price enablers in stores which are children of this store in the store hierarchy.
Compliance	`mandatory`		This method is must be implemented.
Method	useIsolatedStoreView
Description	Isolates the view for methods in this session. An isolated view restricts lookups to this store only.
Compliance	`mandatory`		This method is must be implemented.
Method	useActivePriceEnablerView
Description	Only active price enablers are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	useAnyStatusPriceEnablerView
Description	All active and inactive price enablers are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	useEffectivePriceEnablerView
Description	Only price enablers whose effective dates are current are returned by methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	useAnyEffectivePriceEnablerView
Description	All price enablers of any effective dates are returned by all methods in this session.
Compliance	`mandatory`		This method is must be implemented.
Method	getPriceEnabler
Description	Gets the `PriceEnabler` specified by its `Id`. In plenary mode, the exact `Id` is found or a `NOT_FOUND` results. Otherwise, the returned `PriceEnabler` may have a different `Id` than requested, such as the case where a duplicate `Id` was assigned to a `PriceEnabler` and retained for compatibility.

Method	getPriceEnablersByIds
Description	Gets a `PriceEnablerList` corresponding to the given `IdList`.In plenary mode, the returned list contains all of the price 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 `PriceEnablers` may be omitted from the list and may present the elements in any order including returning a unique set.
Parameters	`osid.id.IdList`	`priceEnablerIds`	the list of `Ids` to retrieve
