Detailed Description

The DtDriver for CIGI.

Provides communication between the IG (DtDe) and the DtCigiConnection which does most of the actual processing of CIGI messages (except for those that need the DtDe, like HAT/HOT/LOS, etc)

virtual const std::string& makVrv::DtCigiDriver::className ( ) const

virtual

Get this Driver's class name.

Implements makVrv::DtDriver.

const DtCigiConnectionInitializer & makVrv::DtCigiDriver::connectionSettings ( ) const

inline

Returns the CIGI connection settings.

References myInitializer.

virtual void makVrv::DtCigiDriver::setConnectionSettings ( const DtCigiConnectionInitializer & settings )

virtual

Set the connection settings.

virtual DtConfiguration makVrv::DtCigiDriver::createConfiguration ( ) const

virtual

Create a configuration for the driver.

Reimplemented from makVrv::DtDriver.

virtual void makVrv::DtCigiDriver::realizeConfiguration ( const DtConfiguration & config )

virtual

Realize the driver via a generic configuration.

Reimplemented from makVrv::DtDriver.

virtual void makVrv::DtCigiDriver::run ( )

virtual

Function that will be called when the thread is started.

Runs the loop that ticks the driver, processes CIGI messages, updates the IG, and sends any responses/start-of-frame.

virtual DtAgentManagerInterface& makVrv::DtCigiDriver::sceneInterface ( )

virtual

Returns the scene interface.

Returns an asynchronous interface if running a separate thread.

Reimplemented from makVrv::DtDriver.

virtual

Returns whether the CIGI Driver is using a separate thread for CIGI message processing.
