Interface AgentAgencySession

All Superinterfaces:

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

public interface AgentAgencySession
extends OsidSession

This session provides methods to retrieve Agents to Agency mappings. An Agent may appear in multiple Agency objects. Each Agency may have its own authorizations governing who is allowed to look at it.

This lookup session defines two views:

• comparative view: elements may be silently omitted or re-ordered
• plenary view: provides a complete result set or is an error condition
