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

Interface	osid.subscription.rules.SubscriptionEnablerPublisherSession
Implements	`osid.OsidSession`
Description	This session provides methods to retrieve `SubscriptionEnabler` to `Subscription` mappings. A `SubscriptionEnabler` may appear in multiple `Subscription` objects. Each subscription 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
Method	canLookupSubscriptionEnablerPublishertMappings
Description	Tests if this user can perform lookups of subscription enabler/publisher 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	useComparativeSubscriptionEnablerPublisherView
