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.

Inheritance

Static Methods

bind(host, int port, {bool reuseAddress: true}) → Future<RawDatagramSocket>

Creates a new raw datagram socket binding it to an address and port.

Constructors

RawDatagramSocket()

Properties

address → InternetAddress

Returns the address used by this socket.

read-only
broadcastEnabled → bool

Set or get, whether IPv4 broadcast is enabled.…

read / write
first → Future<RawSocketEvent>

Returns the first element of the stream.…

read-only, inherited
hashCode → int

Get a hash code for this object.…

read-only, inherited

Reports whether this stream is a broadcast stream.

read-only, inherited
isEmpty → Future<bool>

Reports whether this stream contains any elements.…

read-only, inherited
last → Future<RawSocketEvent>

Returns the last element of the stream.…

read-only, inherited
length → Future<int>

Counts the elements in the stream.

read-only, inherited
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
runtimeType → Type

A representation of the runtime type of the object.

read-only, inherited
single → Future<RawSocketEvent>

read-only, inherited
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.
