Interface SubscriptionPublisherSession

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidSession

public interface SubscriptionPublisherSession
extends OsidSession

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
