public interface DeviceQuerySession extends OsidSession
This session provides methods for searching among Device
objects. The search query is constructed using the DeviceQuery.
This session defines views that offer differing behaviors for searching.
Devices may have a query record indicated by their respective record
types. The query record is accessed via the DeviceQuery.
