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.

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.READ_CLOSED will never be received as an UDP socket cannot be closed by a remote peer.

Static Methods

bind ( host, int port, {bool reuseAddress: true} ) → Future<RawDatagramSocket>
Creates a new raw datagram socket binding it to an address and port.

Instance Properties

readEventsEnabled bool
read/write
Set or get, if the RawDatagramSocket should listen for RawSocketEvent.READ events. Default is true.
writeEventsEnabled bool
read/write
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 anoth...
multicastLoopback bool
read/write
Set or get, whether multicast traffic is looped back to the host.
multicastHops int
read/write
Set or get, the maximum network hops for multicast packages originating from this socket.

read/write
Set or get, the network interface used for outgoing multicast packages.

read/write
Set or get, whether IPv4 broadcast is enabled.
