Interface EngineQuerySession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
All Known Subinterfaces:
EngineSearchSession
public interface EngineQuerySession extends OsidSession

This session provides methods for searching Engines. The search query is constructed using the EngineQuery. The engine record Type also specifies the record for the engine query.

Engines may have a query record indicated by their respective record types. The query record is accessed via the EngineQuery. The returns in this session may not be cast directly to these interfaces.

Like all OsidSessions, EngineQuerySessions are dedicated to single processing threads and a single authenticated user.
