OSID - osid.messaging.ReceiptMailboxSession Service Interface Definition

Interface	osid.messaging.ReceiptMailboxSession
Implements	`osid.OsidSession`
Used By	`osid.messaging.MessagingManager`
Used By	`osid.messaging.MessagingProxyManager`
Description	This session provides methods to retrieve `Receipt` to `Mailbox` mappings. A `Receipt` may appear in multiple `Mailboxes`. Each `Mailbox` may have its own authorizations governing who is allowed to look at it. This lookup session defines several views: comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete result set or is an error condition Like all `OsidSessions`, `ReceiptMailboxSessions` are dedicated to single processing threads and a single authenticated user.
Method	canLookupReceiptMailboxMappings
Description	Tests if this user can perform lookups of receipt/mailbox mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known lookup 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 looking up mappings is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	useComparativeMailboxView
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 must be implemented.
Method	usePlenaryMailboxView
Description	A complete view of the `Receipt` and `Mailbox` 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 must be implemented.
