Class DServer

DServer accepts TCP connections and generates an event for each one. DServer is an abstract class, and should be inherited by a child that implements its event handlers. See Simple Server for sample DServer code.

Functions

• DServer(DEngine *engine)
• bool bind(IpVersion ipVersion, uint16_t portNumber)
• void close(void)
• string getErrMsg(void)
• bool startListening(void)

Event Handlers

• virtual void connectHandler(boost::asio::ip::tcp::socket *socket) = 0
• virtual void errorHandler(string errorDesc) = 0

DServer(DEngine *engine)

The constructor registers this DServer with the given engine.

bool bind(IpVersion ipVersion, uint16_t portNumber)

Binds the server to the specified portNumber. ipVersion should be set to either DA_IPV4 or DA_IPV6. This function returns false if it couldn't bind the socket, and sets errMsg with a description of the problem.

void close(void)

string getErrMsg(void)

bool startListening(void)

Start listening for connections. connectHandler will be called whenever a client connects. Returns false on errors and sets errMsg.

virtual void connectHandler(boost::asio::ip::tcp::socket *socket) = 0

This event handler is called when a client connects. socket can be used to construct a DClient, which will handle the connection. If you prefer to use socket directly, you are responsible for deleting it when finished.

virtual void errorHandler(string errorDesc) = 0
