Member Functions

accept virtual

virtual bool accept(
    const StreamSocket & socket
) = 0;

Returns true if the given StreamSocket connection should be handled, and passed on to the TCPServerDispatcher.

Returns false if the socket should be closed immediately.

The socket can be prevented from being closed immediately if false is returned by creating a copy of the socket. This can be used to handle certain socket connections in a special way, outside the TCPServer framework.
