Implementsosid.OsidSession
Description

This session provides methods to retrieve Subscription to Publisher mappings. A Subscription may appear in multiple Publishers. Each Publisher 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
MethodcanLookupSubscriptionPublisherMappings
Description

Tests if this user can perform lookups of subscription/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 intendedas a hint to an application that may opt not to offer lookup operations to unauthorized users.

Returnboolean false if looking up mappings is not authorized, true otherwise
