DCUtRUdpCoordinator class
Coordinates DCUtR hole-punching over a UdpSocket.
Each outgoing datagram is prefixed with a 4-byte magic (0x44435452,
i.e. "DCTR") followed by the serialized DCUtRMessage. Incoming
datagrams are parsed, validated, and used to drive the supplied
DCUtRStateMachine.
Constructors
- DCUtRUdpCoordinator(UdpSocket _socket, DCUtRStateMachine _stateMachine)
- Creates a coordinator that drives DCUtR over the supplied UDP socket and state machine.

sendConnect(
InternetAddress addr, int port, List< int> observedAddr) → Future<bool> -
Sends a DCUtR CONNECT message to
addr:portand transitions the state machine withonConnectSent(). -

-
stopListening(
) → void - Cancels the subscription on the UDP socket.
