RawSocket class
A RawSocket is an unbuffered interface to a TCP socket.
The raw socket delivers the data stream in the same chunks as the underlying operating system.
It is not the same as a POSIX raw socket.

Properties
- address → InternetAddress
-
Returns the InternetAddress used to connect this socket.
read-only
- port → int
-
Returns the port used by this socket.
read-only
- readEventsEnabled ↔ bool
-
Set or get, if the RawSocket should listen for RawSocketEvent.read
events. Default is
true
.read / write - remoteAddress → InternetAddress
-
Returns the remote InternetAddress connected to by this socket.
read-only
- remotePort → int
-
Returns the remote port connected to by this socket.
read-only
- writeEventsEnabled ↔ bool
-
Set or get, if the RawSocket 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 -
first
→ Future<
RawSocketEvent> -

last
→ Future<
RawSocketEvent> -

Methods
-
available(
) → int - Returns the number of received and non-read bytes in the socket that can be read.
-
close(
) → Future< RawSocket> - Closes the socket. Returns a Future that completes with this when the underlying connection is completely destroyed. [...]
-
getRawOption(
RawSocketOption option ) → Uint8List -
Use getRawOption to get low level information about the RawSocket. See
RawSocketOption for available options. [...]
@Since("2.2")
-
read(
[int len] ) → Uint8List -
Read up to
len
bytes from the socket. This function is non-blocking and will only return data if data is available. The number of bytes read can be less thenlen
if fewer bytes are available for immediate reading. If no data is availablenull
is returned. -
setOption(
SocketOption option, bool enabled ) → bool - Use setOption to customize the RawSocket. See SocketOption for available options. [...]
-
setRawOption(
RawSocketOption option ) → void -
Use setRawOption to customize the RawSocket. See RawSocketOption for
available options. [...]
@Since("2.2")
-
shutdown(
SocketDirection direction ) → void -
Shutdown the socket in the
direction
. Calling shutdown will never throw an exception and calling it several times is supported. Calling shutdown with either SocketDirection.both or SocketDirection.receive can result in a RawSocketEvent.readClosed event. -
write(
List< int> buffer,[int offset, int count] ) → int -
Writes up to
count
bytes of the buffer fromoffset
buffer offset to the socket. The number of successfully written bytes is returned. This function is non-blocking and will only write data if buffer space is available in the socket. [...] -
any(
bool test(RawSocketEvent element ) ) → Future< bool> -
Checks whether
test
accepts any element provided by this stream. [...]inherited -

mapped to a new event. [...]

Returns whether
needle
occurs in the elements provided by this stream. [...]inherited -

Skips data events if they are equal to the previous data event. [...]
inherited
-
drain<

occurred. [...]
