Interface QueueDistributorSession

All Superinterfaces:

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

public interface QueueDistributorSession
extends OsidSession

This session provides methods to retrieve Queue to Distributor mappings. A Queue may appear in multiple Distributor objects. Each distributor 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

QueueList	getQueuesByDistributor(Id distributorId) Gets the list of queues associated with a Distributor.
QueueList	getQueuesByDistributors(IdList distributorIds) Gets the list of queues corresponding to a list of Distributors.
void	useComparativeQueueDistributorView() The returns from the lookup methods may omit or translate elements based on this session, such as authorization, and not result in an error.
void	usePlenaryQueueDistributorView() A complete view of the Queue and Distributor returns is desired.

Method Detail

canLookupQueueDistributorMappings

boolean canLookupQueueDistributorMappings()

Tests if this user can perform lookups of queue/distributor 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.

useComparativeQueueDistributorView

void useComparativeQueueDistributorView()

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.

usePlenaryQueueDistributorView

void usePlenaryQueueDistributorView()

A complete view of the Queue and Distributor 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.
