Member Function Documentation

virtual unsigned int DtLanForwarderPort::abortPendingConnections ( )

virtual

Abort any embryonic connections.

Since LAN port does not initiate connections it cannot abort them either, so this method always returns 0

Implements DtForwarderPort.

virtual int DtLanForwarderPort::checkConnectionStatus ( const DtInetAddrAndPort *  target = 0 )

virtual

Test for lost connections - returns true if targeted connection is active or if no target specified returns false if at least one drop detected.

Implements DtForwarderPort.

virtual void DtLanForwarderPort::clearNeededConnections ( )

virtual

Clear the list of connections that this forwarder needs to establish.

Since the LAN port does not try to establish connections, this method does nothing.

Implements DtForwarderPort.

virtual DtAddressPortList DtLanForwarderPort::connections ( ) const

virtual

Get the list of all current connections to this port.

Implements DtForwarderPort.

static DtForwarderPort* DtLanForwarderPort::create ( const DtRIDParameters *  params, const DtBoost::shared_ptr< DtRouteMap >  routes, const MAKRti::DtInetAddr &  host, int  forwarderPort, const MAKRti::DtInetAddr &  forwardertoConnectTo  )

static

Creates an instance of a DtLanForwarderPort.

virtual void DtLanForwarderPort::dropMulticastGroup ( const MAKRti::DtInetAddr &  mcastAddr )

virtual

Implements DtForwarderPort.

virtual const DtFederateTrackingFilter* DtLanForwarderPort::fedTrackingFilter ( ) const

virtual

return federateTrackingFilter

virtual bool DtLanForwarderPort::flush ( )

inlinevirtual

Flush any unsent/buffered packets; return true if flush sent data.

Reimplemented from DtForwarderPort.

virtual DtAddressMsgPair DtLanForwarderPort::getNextMsg ( )

virtual

Get the next message to forward and the source connection.

Implements DtForwarderPort.

virtual bool DtLanForwarderPort::isReady ( ) const

virtual

Is the Port fully usable and available?

Implements DtForwarderPort.

virtual void DtLanForwarderPort::listenToMulticastGroup ( const MAKRti::DtInetAddr &  mcastAddr )

virtual

Listen / drop multicast groups (LAN-port-only)

Implements DtForwarderPort.

DtLanForwarderPort& DtLanForwarderPort::operator= ( const DtLanForwarderPort &  orig )

protected

unsigned int DtLanForwarderPort::pendingConnectionsAborted ( )

virtual

Return count of aborted connections.

Since LAN port does not initiate connections it cannot abort them either, so this method always returns 0

Implements DtForwarderPort.

virtual bool DtLanForwarderPort::populateConnectionInformation ( unsigned int &  numForwarderClientConns, unsigned int &  numForwarderExecConns, std::vector< MAKRti::DtString > &  clientConnectionHostNames, std::vector< MAKRti::DtInetAddr > &  clientConnectionAddrs  ) const

virtual

virtual void DtLanForwarderPort::selectParams ( MAKRti::DtSelectParamWithWrite &  selectParams )

virtual

Add this port's current select() notification set to the passed set.

Implements DtForwarderPort.

virtual void DtLanForwarderPort::sendByTransport ( const DtForwarderMsg &  msg ) const

virtual

Check transport metadata and send message to appropriate destinations.

Implements DtForwarderPort.

virtual void DtLanForwarderPort::sendToAllReliable ( const DtForwarderMsg &  msg ) const

virtual

Send a message via reliable transport to all available destinations.

Implements DtForwarderPort.

virtual void DtLanForwarderPort::sendToListReliable ( const DtForwarderMsg &  msg, const DtAddressPortList &  destinations  ) const

virtual

Send a message via reliable transport to the specified list of destinations.

Implements DtForwarderPort.

static void DtLanForwarderPort::setCreatorFunction ( DtForwarderPortCreatorFcn  creator )

static

Call this function to set an alternate creator function With this function, users can replace this DtLanForwarderPort with their own derived class.

virtual void DtLanForwarderPort::setForwarderId ( unsigned long  id )

virtual

Set forwarder ID.

When forwarder is configured via routes files, forwarderID is known at construction, but when configured dynamically it is determined by interactions between peer forwarders and must be set.

Reimplemented from DtForwarderPort.

virtual bool DtLanForwarderPort::updateFederateConnectionId ( unsigned long  orig, unsigned long  final  )

virtual

Update locally connected federate connection ID (LAN-port-only)

Implements DtForwarderPort.

virtual void DtLanForwarderPort::updateRoutes ( )

virtual

Handle changes to the Routing map.

Implements DtForwarderPort.
