Detailed Description

UServerSocket.

example:

creates a ServerSocket on this port
 UServerSocket* servs = new UServerSocket(666);

newConnection() will be called each time 'servs' receives a connection request
NB: in this example, 'servs' is given as an argument to the non-member fonction
newConnection() via ucall(). Aternatively, newConnection() could be an instance 
method of an object having a UServerSocket instance, see UCall for more info.

 servs->onInput(ucall(servs, newConnection));

 void newConnection(UServerSocket* servs) {
accepts the connection and returns the corresponding socket
     USocket* s = servs->accept();
     s->onInput(ucall(s, socketInputCB));  // see USocket
     ....
 }

Member Function Documentation

accept()

USocket * ubit::UServerSocket::accept ( )

virtual

listens for a connection to be made and accepts it.

This method blocks until a connection is made. It is typically called in a callback function: see onInput() and class UServerSocket

Note: accept() calls createSocket() to create the new socket. By default this functions returns {new USocket}. It can be redefined by UServerSocket subclasses to create appropriate socket objets.

onInput()

void ubit::UServerSocket::onInput ( UCall &  c )

virtual

adds a callback that is fired when data is received on the server socket.

accept() is typically called in such a callback
