Detailed Description

Instances of the DtTcpForwarder__vl__ class manage TCP connections for variants of Forwarder (servers) which accept TCP connections.

Constructor & Destructor Documentation

DtTcpForwarder__vl__::DtTcpForwarder__vl__	(	int	port,
		const DtInetAddr &	networkInterface = `DtInetAddr::inaddrAny()`
	)

Constructor.

Accepts port number and interface on which to listen for incoming client connections.

DtTcpForwarder__vl__::DtTcpForwarder__vl__ ( )

Constructor which will NOT open up a socket manager.

Instead, construction of the socket manager is left to a derived class.

DtTcpForwarder__vl__::~DtTcpForwarder__vl__ ( )

virtual

Destructor.

References mySocketMgr.

DtTcpForwarder__vl__::DtTcpForwarder__vl__ ( const DtTcpForwarder__vl__ & )

private

Copy CTOR Not Implemented – Copy Not Allowed!

Member Function Documentation

DtTcpForwarder__vl__& DtTcpForwarder__vl__::operator= ( const DtTcpForwarder__vl__ & )

private

Assignment Operator Not Implemented – Assignment Not Allowed!

void DtTcpForwarder__vl__::readAndForward	(	DtTime	maxTimeOverAll,
		DtTime	maxTimePerSocket
	)

virtual

Retrieve all messages from each TCP connection and forward each to all other TCP connections.

The amount of time spent processing each individual connection is limited by maxTimePerSocket and the total amount of time spent processing all connections is limited by maxTimeOverAll.

References DtTcpMsgSocket::isConnected(), myBeginSock, myClock, mySocketMgr, DtTcpMsgSocketMgr::removeAndDelete(), DtTcpMsgSocketMgr::socketIter(), and DtTcpMsgSocketMgr::socketSet().

void DtTcpForwarder__vl__::readAndForward	(	DtTcpMsgSocket *	sock,
		DtTime	stopTime
	)

virtual

Retrieve all messages from a single TCP connection and forward each to all other TCP connections, stopping when the clock reaches the specified stop time.
