QueueSearchSession

public interface QueueQuerySession extends OsidSession

This session provides methods for searching among Queue objects. The search query is constructed using the QueueQuery.

This session defines views that offer differing behaviors for searching.

  • federated broker view: searches include queues in brokers of which this broker is an ancestor in the broker hierarchy
  • isolated broker view: searches are restricted to queues in this broker

Queues may have a query record indicated by their respective record types. The query record is accessed via the QueueQuery.
