Member Enumeration Documentation

enum Faith::Socket::SocketError


Constructor & Destructor Documentation

Faith::Socket::Socket ( const Faith::String address,
int  port,
Object parent = 0 

connects to the address address and the port port

The actual connection doesn't occur until connect() is called

Faith::Socket::Socket ( int  fd,
Object parent = 0 

creates a socket from the given file descriptor, which is already open and connected

Faith::Socket::Socket ( Object parent = 0  ) 

Faith::Socket::~Socket (  ) 

closes the socket if it is open

Member Function Documentation

void Faith::Socket::canRead (  )  [signal]

void Faith::Socket::canWrite (  )  [signal]

void Faith::Socket::close (  )  [slot]

Terminate the call. The other end will be told after having recieved all that was written

void Faith::Socket::connect (  )  [slot]

begins the connection to the peer

This function will emit connected or connectFailed when it is done

After this, canRead and canWrite may be emitted as well

void Faith::Socket::connected (  )  [signal]

void Faith::Socket::connectFailed (  )  [signal]

SocketError Faith::Socket::error (  )  const [inline]

the error state. If there is no error, returns NoError

bool Faith::Socket::hasData (  )  const

true if read can read something

bool Faith::Socket::isClosed (  )  const

true if the socket has been closed and there is no more data to read

bool Faith::Socket::isConnected (  )  const

There is another end connected

bool Faith::Socket::isConnectionFailed (  )  const

The connection has failed (and connectFailed was emitted

Faith::String Faith::Socket::peer (  )  const

the address of the peer, or an empty string if the peer is unavailable

void Faith::Socket::peerDisconnected (  )  [signal]

emitted when the other end disconnects (before you do, that is) (The next read will return 0)

int Faith::Socket::read ( void *  data,
int  count 

reads from the socket into data

this is a non-blocking operation, so if data is not immediately available, a value less than count may be returned (even 0)

data is the array to write into, it has a size of at length count
count is the number of bytes to read
the number of bytes read, possibly 0 if the other end has closed the socket, or there was an error

void Faith::Socket::setPeer ( const Faith::String address,
int  port 

sets the address to connect to

int Faith::Socket::write ( const void *  data,
int  count 

writes into the socket from data

This is non-blocking, so it may not write all the data specified, returning how much actually was written

data is the array to read the data from, it has a size no smaller than count
count the number of bytes to attempt to write
the number of bytes written, possibly 0 if there was an error
