public interface BrokerQuerySession extends OsidSession

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

This session defines views that offer differing behaviors for searching.

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

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