I am trying to implement support for the UDP functionality I need. I think
that I need to implement the following classes:
For server support:
UDPPort(udp.Port) - adding support for broadcast
ConnectedUDPPort(UDPPort) - connected variant
For client (connection) support:
UDPConnectionBase(FileDescriptor) - creation of non-bound UDP sockets
UDPConnection(UDPConnectionBase) - addition of write method to implement
UDPConnectedConnection(UDPConnectionBase) - support for 'connected' UDP socket
and write method without host,port arguments.
UDPConnector(base.Connector) - connector class that can create use the
UDPConnectedConnector(UDPConnector) - one that works with
Extend the IReactorUDP interface and reactor implementation to support
connectXXX methods for the new connector types.
I am trying to support the creation of UDP connectors that are meant for
sending datagrams and will never be bound to a local port and listened on.
The current support for UDP does not implement and UDP connector type objects
only UDP Port type objects. This means that a bind is always performed even
when the connection is only meant for sending.
I have most of the implementation written (at least in outline).
One question. It appears to me that for UDP connection objects that concept of
a protocol does not make much sense. The IUDPTransport interface does have a
read method (as you would expect) so the protocol would never be called. This
also calls in to question the need for a 'protocol factory' for such
connections. Am I correct in this or am I missing something?
