OSID - osid.bidding.AuctionLookupSession Service Interface Definition

Interface	osid.bidding.AuctionLookupSession
Implements	`osid.OsidSession`
Used By	`osid.bidding.BiddingManager`
Used By	`osid.bidding.BiddingProxyManager`
Description	This session provides methods for retrieving `Auctions`. The `Auction` represents a fixed connection between two `Items`. 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 auction house view: All auction methods in this session operate, retrieve and pertain to auctions defined explicitly in the current auction house. Using an isolated view is useful for managing `Auctions` with the `AuctionAdminSession`. federated auction house view: All auction methods in this session operate, retrieve and pertain to all auctions defined in this auction house and any other auctions implicitly available in this auction house through auction house inheritence. active auction view: All auction lookup methods return active auctions. any status auction view: Active and inactive auctions are returned from methods. 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 `useFederatedAuctionHouseView()` and `useIsolatedAuctionHouseView()` behave as a radio group and one should be selected before invoking any lookup methods.
