	Send a response, for functions that have multiple responses make this call.
virtual void	queueResponse (DtResponse response)
	Queue a response for future sending.
virtual void	sendQueuedResponses ()
	Sends all queued responses and clears the queue.
virtual void	emptyResponseQueue ()
	Empty the response queue (deleting any unsent responses).

Constructor & Destructor Documentation

MAKLogger::DtLgrCommandHandler::DtLgrCommandHandler	(	const DtString &	name,
		DtRuntimeCommandFactory *	,
		DtCommandDispatcherSP
	)

Constructor which provides the name, the runtime factory, and the dispatcher which receives and transmits commands.

virtual MAKLogger::DtLgrCommandHandler::~DtLgrCommandHandler ( )

virtual

DTOR.

Member Function Documentation

void MAKLogger::DtLgrCommandHandler::addCommandHandler ( const DtCommandDefinition &  commandDef, DtCommandFunctorSP  commandFunctor  )

protected

Add a commandHandler, this should not be virtual as it is called in constructors.

DtCommandDispatcherSP MAKLogger::DtLgrCommandHandler::dispatcher

(

)

Get the dispatcher the command handler is connected to.

virtual const DtString& MAKLogger::DtLgrCommandHandler::driverInfo ( )

virtual

Get the name of the driver.

virtual const DtString& MAKLogger::DtLgrCommandHandler::driverName ( ) const

virtual

Get the name of the driver.

virtual void MAKLogger::DtLgrCommandHandler::emptyResponseQueue ( )

protectedvirtual

Empty the response queue (deleting any unsent responses).

virtual bool MAKLogger::DtLgrCommandHandler::getPipeline ( )

pure virtual

Attempt to acquire the pipeline.

Return values

true	The pipeline has been acquired.
false	The pipeline has not been acquired.

Implemented in MAKLogger::DtLgrSimDriver, MAKLogger::DtStateObserverModel, MAKLogger::DtLgrEditorDriver, MAKLogger::DtLgrRecordDriver, and MAKLogger::DtLgrPlaybackDriver.

virtual bool MAKLogger::DtLgrCommandHandler::hasPipeline ( ) const

pure virtual

Does this object own the pipeline.

Return values

true	The pipeline is owned.
false	The pipeline is not owned.

Implemented in MAKLogger::DtLgrSimDriver, MAKLogger::DtStateObserverModel, MAKLogger::DtLgrEditorDriver, MAKLogger::DtLgrRecordDriver, and MAKLogger::DtLgrPlaybackDriver.

void MAKLogger::DtLgrCommandHandler::lock

(

)

Locks the Command Handler.

virtual void MAKLogger::DtLgrCommandHandler::processCommand ( const DtCommand &  command )

virtual

Process a specific command.

virtual void MAKLogger::DtLgrCommandHandler::queueResponse ( DtResponse  response )

protectedvirtual

Queue a response for future sending.

virtual bool MAKLogger::DtLgrCommandHandler::releasePipeline ( )

pure virtual

Attempt to release the pipeline.

This function is called when the pipeline has been requested by a different driver. If the driver can't release the pipeline it will return false. By default this method simply succeeds. If the driver should override this function if it wishes to deny the request.

Return values

true	The pipeline has been released.
false	The pipeline has not been released.

Implemented in MAKLogger::DtStateObserverModel, MAKLogger::DtLgrSimDriver, MAKLogger::DtLgrEditorDriver, MAKLogger::DtLgrRecordDriver, and MAKLogger::DtLgrPlaybackDriver.

void MAKLogger::DtLgrCommandHandler::removeCommandHandler ( const DtCommandDefinition &  commandDef )

protected

Remove a commandHandler, this is typically not called but necessary for replacing a command handler.

virtual void MAKLogger::DtLgrCommandHandler::sendQueuedResponses ( )

protectedvirtual

Sends all queued responses and clears the queue.

virtual void MAKLogger::DtLgrCommandHandler::sendResponse ( DtResponse  response )

protectedvirtual

Send a response, for functions that have multiple responses make this call.

virtual void MAKLogger::DtLgrCommandHandler::tick ( )

pure virtual

Tick the driver, cause it to do anything on a regular basis.

Implemented in MAKLogger::DtStateObserverModel, MAKLogger::DtLgrSimDriver, MAKLogger::DtLgrEditorDriver, MAKLogger::DtLgrHlaSimDriver, MAKLogger::DtLgrRecordDriver, and MAKLogger::DtLgrPlaybackDriver.

void MAKLogger::DtLgrCommandHandler::unlock

(

)

Unlocks the Command Handler.
