Member Function Documentation

accept()

int df::NetworkManager::accept

(

)

Accept network connection.

If successful, generate EventNetwork (accept). Return socket if new connection. Return -1 if no new connection, but no error. Return -2 if error.

close()

int df::NetworkManager::close

(

int

sock = -1

)

Close network connection on indicated socket (-1 for all).

If successful, generate EventNetwork (close). Return 0 if success, else -1.

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 if success, -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

index = 0

)

const

Return socket at indicated index. -1 if out of range.

isConnected()

bool df::NetworkManager::isConnected

(

int

sock = -1

)

const

Check if socket is connected.

Default (-1) checks if any socket is connected. Return true if (any) socket is connected, else false.

isData()

int df::NetworkManager::isData

(

int

sock = 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

Return true only for network events.

Return false for other engine events.

Reimplemented from df::Manager.

receive()

int df::NetworkManager::receive	(	void *	buffer,
		int	bytes,
		bool	leave,
		int	sock = 0
	)

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

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 = -1
	)

Send bytes from buffer to connected network socket (-1 for all).

Return 0 if success, -1 if error.

setDelay()

int df::NetworkManager::setDelay	(	int	new_delay,
		int	sock = 0
	)

Set delay amount added to outgoing messages (in ticks).

Return 0 if ok, else -1.

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.
