Member Function Documentation

accept()

int df::NetworkManager::accept

(

)

Accept network connection.

If successful, generate EventNetwork (accept). Return sock index if new connection (note, 0 for first). Return -1 if no new connection, but no error. Return -2 if errror.

close()

int df::NetworkManager::close

(

int

sock_index = 0

)

Close network connection on indicated socket.

Return 0 if success, else -1.

closeAll()

int df::NetworkManager::closeAll

(

)

Close all network connections.

Return 0 if success, else negative number.

connect()

int df::NetworkManager::connect	(	std::string	host,
		std::string	port = DRAGONFLY_PORT
	)

Make network connection to host at port.

If successful, generate EventNetwork (connect). Return return socket index if success, -1 if error.

genDataEvents()

int df::NetworkManager::genDataEvents

(

int

sock_index = 0

)

const

If complete network message on indicated socket, (first int is message size, in bytes) generate EventNetwork (data).

Return 1 if generated event, 0 if no message, -1 if error.

getInstance()

static NetworkManager & df::NetworkManager::getInstance ( )

static

Get the one and only instance of the NetworkManager.

getMaxConnections()

int df::NetworkManager::getMaxConnections

(

)

const

Get maximum number of connections.

getNumConnections()

int df::NetworkManager::getNumConnections

(

)

const

Get number of connected sockets.

getSocket()

int df::NetworkManager::getSocket

(

int

sock_index = 0

)

const

Return system socket from socket index, -1 if error.

isAnyData()

int df::NetworkManager::isAnyData

(

)

const

Check if data on any connected socket.

Return index of first socket with data. Return -1 if no socket has data.

isConnected()

bool df::NetworkManager::isConnected

(

int

sock_index = 0

)

const

Return true if socket is connected, else false.

isData()

int df::NetworkManager::isData

(

int

sock_index = 0

)

const

Check if network data on indicated socket.

Return amount of data (0 if no data), -1 if not connected or error.

isServer()

bool df::NetworkManager::isServer

(

)

const

Return true if successufully setup as server, else false.

isValid()

bool df::NetworkManager::isValid ( std::string  event_type ) const

overridevirtual

Accept only network events.

Returns false for other engine events.

Reimplemented from df::Manager.

receive()

int df::NetworkManager::receive	(	void *	buffer,
		int	nbytes,
		bool	leave,
		int	sock_index = 0
	)

Receive from connected network socket (no more than nbytes).

If leave is true, don't remove data from socket (peek). Return number of bytes received, -1 if error.

send()

int df::NetworkManager::send	(	const void *	buffer,
		int	bytes,
		int	sock_index = 0
	)

Send bytes from buffer to connected network socket.

Return 0 if success, -1 if error.

setMaxConnections()

void df::NetworkManager::setMaxConnections

(

int

new_max_sock

)

Set maximum number of connections.

setServer()

int df::NetworkManager::setServer	(	bool	server = true,
		std::string	port = DRAGONFLY_PORT
	)

Setup NetworkManager as server (if false, reset to client).

Return 0 if ok, else -1.

shutDown()

void df::NetworkManager::shutDown ( )

overridevirtual

Shut down NetworkManager.

Reimplemented from df::Manager.

startUp()

int df::NetworkManager::startUp ( )

overridevirtual

Start up NetworkManager.

Reimplemented from df::Manager.
