RawDatagramSocket class
The RawDatagramSocket is a low-level interface to an UDP socket, exposing the raw events signaled by the system. It's a Stream of RawSocketEvents.
Note that the event RawSocketEvent.readClosed will never be received as an UDP socket cannot be closed by a remote peer.

Constructors
Properties
- address → InternetAddress
-
Returns the address used by this socket.
read-only
- broadcastEnabled ↔ bool
-
Set or get, whether IPv4 broadcast is enabled. [...]
read / write
- multicastHops ↔ int
-
Set or get, the maximum network hops for multicast packages
originating from this socket. [...]
read / write
- multicastInterface ↔ NetworkInterface
-
Set or get, the network interface used for outgoing multicast packages. [...]
read / write
- multicastLoopback ↔ bool
-
Set or get, whether multicast traffic is looped back to the host. [...]
read / write
- port → int
-
Returns the port used by this socket.
read-only
- readEventsEnabled ↔ bool
-
Set or get, if the RawDatagramSocket should listen for
RawSocketEvent.read events. Default is
true.read / write - writeEventsEnabled ↔ bool
-
Set or get, if the RawDatagramSocket should listen for
RawSocketEvent.write events. Default is
true. This is a one-shot listener, and writeEventsEnabled must be set to true again to receive another write event.read / write -
