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 error.

◆ close()

int df::NetworkManager::close ( int  sock_index = 0)

Close network connection on indicated socket.

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

◆ closeAll()

int df::NetworkManager::closeAll ( )

Close all network connections.

If successful, generate EventNetwork (close), for each. 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 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

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_index = 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_index = 0 
)

Send bytes from buffer to connected network socket.

Return 0 if success, -1 if error.

◆ setDelay()

int df::NetworkManager::setDelay ( int  new_delay,
int  sock_index 
)

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.
