Interface CompositionRepositorySession

All Superinterfaces:

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

public interface CompositionRepositorySession
extends OsidSession

This session provides methods to retrieve Composition to Repository mappings. A Composition may appear in multiple Repository objects. Each Repository 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 Detail

useComparativeCompositionRepositoryView

void useComparativeCompositionRepositoryView()

The returns from the lookup methods may omit or translate elements based on this session, such as authorization, and not result in an error. This view is used when greater interoperability is desired at the expense of precision.

Compliance:

mandatory - This method is must be implemented.

usePlenaryCompositionRepositoryView

void usePlenaryCompositionRepositoryView()

A complete view of the Composition and Repository returns is desired. Methods will return what is requested or result in an error. This view is used when greater precision is desired at the expense of interoperability.

Compliance:

mandatory - This method is must be implemented.

canLookupCompositionRepositoryMappings

boolean canLookupCompositionRepositoryMappings()

Tests if this user can perform lookups of composition/repository 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.

Returns:

false if looking up mappings is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.
