Member Typedef Documentation

typedef std::list<DtDeRecord> makVrv::DtDeCommunicator::IgRecords

Constructor & Destructor Documentation

virtual makVrv::DtDeCommunicator::~DtDeCommunicator ( )

virtual

DTOR.

makVrv::DtDeCommunicator::DtDeCommunicator ( DtDe &  de, DtDriverConfiguration &  config  )

protected

CTOR. Create derived class instead.

Member Function Documentation

virtual bool makVrv::DtDeCommunicator::initialize ( )

virtual

Initialize, called by Ig after it's member is set.

virtual void makVrv::DtDeCommunicator::listenForMasterIg ( )

virtual

Start listening for a master.

Exceptions

DtCorruptedState

if the DtIG is configured to be a master.

virtual bool makVrv::DtDeCommunicator::hasMasterIg ( ) const

virtual

Check to see if the client has a Master IG.

virtual void makVrv::DtDeCommunicator::disconnectMasterIg ( const std::string &  masterName )

virtual

Disconnect from the Master IG (starts listening automatically)

bool makVrv::DtDeCommunicator::connectToSlaveIg	(	const std::string &	slaveAddr,
		int	port,
		std::string &	igNameOut
	)

Attempt to connect to a slave.

Exceptions

DtCorruptedState

if the DtIG is NOT configured to be a master. If connectToSlaveIg() returns true, igNameOut will contain the name of the connected slave IG.

void makVrv::DtDeCommunicator::disconnectSlaveIg	(	const std::string &	name,
		bool	lostConnection = false
	)

Disconnect a slave IG with a given name. If lostConnection is true, this is being called because the master failed to send to a remote display. This will cause the named RD to be added to the Remote Display Reconnector to attempt re-attachment.

virtual void makVrv::DtDeCommunicator::tick ( )

virtual

Tick the driver.

virtual void makVrv::DtDeCommunicator::addIgRecord ( const DtDeRecord &  record )

virtual

Get the current driver configuration.

Add a client.

virtual void makVrv::DtDeCommunicator::removeIgRecord ( const DtDeRecord &  record, bool  lostConnection = false  )

virtual

Remove a client. The lostConnection flag is set to true if the record is removed because a connection to the display was lost. This is provided to propogate that fact to the signal_clientToByDeleted signal.

DtDeRecord& makVrv::DtDeCommunicator::hostIgRecord

(

)

Get the record for the host IG (aka this de instance that owns the communicator.

DtDeRecord* makVrv::DtDeCommunicator::findRecordByIgName

(

const std::string &

igName

)

Find a record by Ig's name.

DtDeRecord* makVrv::DtDeCommunicator::findRecordByDisplayName

(

const std::string &

displayName

)

Find a record by the Ig's Display name.

bool makVrv::DtDeCommunicator::masterIgOnly

(

)

const

Check to see if only a single master de is in use.

const IgRecords& makVrv::DtDeCommunicator::connectedIgs

(

)

const

Get a set of the current IG instances.

virtual const std::string& makVrv::DtDeCommunicator::name ( ) const

virtual

Return the name of this driver. Composed of the host name and process id.

static const char* makVrv::DtDeCommunicator::className ( )

static

Returns the name of this class. Required for DtSubjectAnnouncer::findInstance().

bool makVrv::DtDeCommunicator::validateSlaveConnection ( const std::string &  ipAddr )

protected

Make slave connectable.

void makVrv::DtDeCommunicator::invalidateSlaveConnection ( const std::string &  ipAddr )

protected

Disallow slave connection.

virtual void makVrv::DtDeCommunicator::addSlave ( DtTcpMessageClient *  client, std::string &  igNameOut  )

protectedvirtual

Add the specified client to the server(s) and returns the client's name in igNameOut.
