Interface ItemBusinessSession

All Superinterfaces:

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

public interface ItemBusinessSession
extends OsidSession

This session provides methods to retrieve Item to Business mappings. An Item may appear in multiple Business objects. Each catalog 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
