OSID - osid.bidding.rules.AuctionProcessorAuctionHouseAssignmentSession Service Interface Definition

Interface	osid.bidding.rules.AuctionProcessorAuctionHouseAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.bidding.rules.BiddingRulesManager`
Used By	`osid.bidding.rules.BiddingRulesProxyManager`
Description	This session provides methods to re-assign `AuctionProcessor` to `AuctionHouse` mappings. An `AuctionProcessor` may appear in multiple `AuctionHouse` objects and removing the last reference to an `AuctionProcessor` is the equivalent of deleting it. Each `AuctionHouse` may have its own authorizations governing who is allowed to operate on it. Adding a reference of an `AuctionProcessor` to another `AuctionHouse` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignAuctionProcessors
Description	Tests if this user can alter auction processor/auction house 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` . This is intended as a hint to an application that may opt not to offer lookup operations to unauthorized users.
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
