A Server object provides member functions for initializing your server application and for running it.
Each application that uses Push Framework classes can only contain one object derived from Server.
Declare your server object at the global level. When you instantiate your server object,
call the available initialization members such as ::setProtocol, ::setClientFactory etc before you call ::start.
class PUSHFRAMEWORK_API Server
/** @name TORs **/
/** @name Configuration **/
\param pProtocol should point to a valid Protocol instance with a lifetime > to the lifetime of the Server instance.
Set the Protocol default instance for all subsequent listeners created without a particular protocol
specification. For more infos see ::createListener
void setProtocol(Protocol* pProtocol);
\param pClientFactory pointer to a ClientFactory object. The object should remain valid till you call Server::stop.
A call to setClientFactory is necessary before calling Server::start.
void setClientFactory(ClientFactory* pClientFactory);
\param port The port number to listen to. If port is used by another application, ::start will fail.
\param pOptions Optional options on how to deal with clients connected to that port.
Push Framework creates a dedicated thread to listen for all incoming connection on the port specified. The pOptions
is very useful when you want to handle clients that support different communication protocol. If pOptions is NULL
the Protocol instance supplied by ::setProtocol will be used.
bool createListener(int port, ListenerOptions* pOptions = NULL);
\param nMaxConnections The default value is 1000.
Restrict the number of simultaneously clients able to be present at your server.
void setMaxConnections(int nMaxConnections);
\param workerCount Number of threads to spawn.
Specify the number of thread to spawn for servicing the incoming requests. If not called,
the library will spawn 2*nLogicalProcessors on the server machine.
void setWorkerCount(int workerCount);
\param serviceId Service id also called the request id.
\param pService reference to the Service instance to be registered.
\param serviceName display name.
Supplies a Service instance address to be invoked for incoming requests identified as belonging the same service id value.
void registerService(unsigned int serviceId, Service* pService, const char* serviceName);
\param serverName Text value.
Sets your server infos. The value is displayed by the remote Dashboard after the "info" command.
void setServerInfos(const char* serverName);
\param ver reference to the results variable.
Query the version of Push Framework.
void getVersion(Version& ver);
\param uLoginExpireDuration Value in seconds. The internal default value is 15 seconds.
If a a new connection is not logged within the specified maximum duration, the library will automatically
shuts it down.
void setLoginExpiryDuration(unsigned int uLoginExpireDuration);
\param ipStart Ip value
\param ipStop Ip value
Specify a range of ip addresses to be blocked.
void addBlockedIPRange(const char* ipStart, const char* ipStop);
\param ipStart Ip value
\param ipStop Ip value
Specify a range of ip addresses to be allowed.
void addPermitIPRange(const char* ipStart, const char* ipStop);
/** @name Profiling and remote control **/
\param sPort The port number to listen to
\param password password to use for monitors authentication. This should be a null terminating string
Allow the remote monitoring dashboard to access this server by connecting to the given listening port and with the given password.
void enableRemoteMonitor(short sPort, const char* password);
\param samplingRate Duration in seconds. A value between 10s and 3mn is OK.
Activates performance profiling. This tells the framework to constantly collect performance measure
that are sampled then sent at the duration rate given by the samplingRate parameter.
void enableProfiling(unsigned int samplingRate);
Deactivates profiling. Remote Monitoring Dashboard can no longer receive performance signals.
However it is still able to send remote commands and receive their corresponding replies.
\param command a null terminating string containing the received user command.
An 256-length buffer. Write a null terminating string to this buffer and return the value of true so the framework sends it as a reply.
virtual bool handleMonitorRequest(const char* command, char* lpOut);
/** @name Start and stop **/
\param startInSeparateThread if false then the call is blocking.
Runs the server. The call is blocking if startInSeparateThread is false.
The method initializes all needed data and launches all necessary threads (example : worker threads, listening threads, ..).
The server is then ready to accept remote connections and service their requests.*/
void start(bool startInSeparateThread = false);
Stops the server. Your application is expected to exit after this call.
You can't call start after stop.*/
Pauses the server. This only affects the listening process.
The server continue to service existing clients till they disconnect.
It only stops from accepting new connections. Also continues to service remote Dashboards.*/
Resumes server. Server is able to accept new connections.
/*********** @name Others *************/
Returns a reference to the ClientFactory previously gathered by the call to ::setClientFactory.
Returns a usable reference to the Broadcasting Manager.
virtual void* workerThreadBegin();
virtual void workerThreadEnd(void*);
virtual OutgoingPacket* getTestPacket();
virtual void disposeOutgoingPacket(OutgoingPacket* pPacket) = 0;
