Detailed Description

Server side of the SimDB socket interface. This class provides the server side functions to simplify the incoming connections handling and the messages sending/receiving.

Member Function Documentation

int ServerHandler::acceptConnection

(

)

Returns

The Socket descriptor of the connection just accepted, or the GENERIC_SOCKET_ERROR macro if something is wrong.

void ServerHandler::closeConnection	(	int	connectedSocket,
		SocketState &	threadState
	)

Chiude una connessione con un certo client

Parameters

connectedSocket	The socket with the client connection.
threadState	State of the thread which handles the connection.

bool ServerHandler::createSocket

(

)

Returns

true if the socket creation succeeds (through the socket() function), false otherwise.

char * ServerHandler::receiveFile	(	int	connectedSocket,
		SocketState &	threadState
	)

Parameters

connectedSocket	The socket with the client connection.
threadState	State of the thread which handles the connection.

Returns

Pointer to the base64-encoded file. We use a pointer for efficiency reasons.

string ServerHandler::receiveMessage	(	int	connectedSocket,
		SocketState &	threadState
	)

Receive a message from the client.

Parameters

connectedSocket	The socket whit the client connection.
threadState	State of the thread which handles the connection.

Returns

String with a message send by the client.

void ServerHandler::sendMessage	(	int	connectedSocket,
		const std::string &	message,
		SocketState &	threadState
	)

Parameters

connectedSocket	The socket with the client connection.
message	The message to send to the client.
threadState	State of the thread which handles the connection.

bool ServerHandler::startListening

(

)

Returns

true if the socket is ready to accept connection requests (through the bind() and listen() functions), false otherwise.

bool ServerHandler::stopService

(

)

Close the listening socket and stop the server communication service.

Returns

true if the operation succeeds, false otherwise.
