The RawSocket is a low-level interface to a socket, exposing the raw events signaled by the system. It's a Stream of RawSocketEvents.

Static Methods

connect(host, int port, {sourceAddress}) → Future<RawSocket>

Creates a new socket connection to the host and port and returns a Future that will complete with either a RawSocket once connected or an error if the host-lookup or connection failed.…

Properties

address → InternetAddress
read-only

Returns the InternetAddress used to connect this socket.

first → Future<RawSocketEvent>
read-only, inherited

Returns the first element of the stream.…

isBroadcast → bool
read-only, inherited

Reports whether this stream is a broadcast stream.

isEmpty → Future<bool>
read-only, inherited

Reports whether this stream contains any elements.…

last → Future<RawSocketEvent>
read-only, inherited

Returns the last element of the stream.…

length → Future<int>
read-only, inherited

Counts the elements in the stream.

port → int
read-only

Returns the port used by this socket.

readEventsEnabled → bool
read / write

Set or get, if the RawSocket should listen for RawSocketEvent.READ events. Default is true.

remoteAddress → InternetAddress
read-only

Returns the remote InternetAddress connected to by this socket.

remotePort → int
read-only

Returns the remote port connected to by this socket.

single → Future<RawSocketEvent>
read-only, inherited

Returns the single element.…

writeEventsEnabled → bool
read / write

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.

Methods

any(bool test(T element)) → Future<bool>
inherited

Checks whether test accepts any element provided by this stream.…

asBroadcastStream({void onListen(StreamSubscription<T> subscription), void onCancel(StreamSubscription<T> subscription)}) → Stream<RawSocketEvent>
inherited

Returns a multi-subscription stream that produces the same events as this.…

asyncExpand(Stream convert(T event)) → Stream
inherited

Creates a new stream with the events of a stream per original event.…

asyncMap(dynamic convert(T event)) → Stream
inherited

Creates a new stream with each data event of this stream asynchronously mapped to a new event.…

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.…

contains(Object needle) → Future<bool>
inherited

Checks whether needle occurs in the elements provided by this stream.…

distinct([bool equals(T previous, T next)]) → Stream<RawSocketEvent>
inherited

Skips data events if they are equal to the previous data event.…

drain([futureValue]) → Future
inherited

Discards all data on the stream, but signals when it's done or an error occured.…

elementAt(int index) → Future<RawSocketEvent>
inherited

Returns the value of the indexth data event of this stream.…

every(bool test(T element)) → Future<bool>
inherited

Checks whether test accepts all elements provided by this stream.…

expand(Iterable convert(T value)) → Stream
inherited

Creates a new stream from this stream that converts each element into zero or more events.…

firstWhere(bool test(T element), {Object defaultValue()}) → Future
inherited

Finds the first element of this stream matching test.…

fold(initialValue, dynamic combine(previous, T element)) → Future
inherited

Reduces a sequence of values by repeatedly applying combine.

forEach(void action(T element)) → Future
inherited

Executes action on each data event of the stream.…

handleError(Function onError, {bool test(error)}) → Stream<RawSocketEvent>
inherited

Creates a wrapper Stream that intercepts some errors from this stream.…

join([String separator = ""]) → Future<String>
inherited

Collects string of data events' string representations.…

lastWhere(bool test(T element), {Object defaultValue()}) → Future
inherited

Finds the last element in this stream matching test.…

listen(void onData(T event), {Function onError, void onDone(), bool cancelOnError}) → StreamSubscription<RawSocketEvent>
inherited

Adds a subscription to this stream.…

map(dynamic convert(T event)) → Stream
inherited

Creates a new stream that converts each element of this stream to a new value using the convert function.…

pipe(StreamConsumer<RawSocketEvent> streamConsumer) → Future
inherited

Binds this stream as the input of the provided StreamConsumer.…

read([int len]) → List<int>

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 then len if fewer bytes are available for immediate reading. If no data is available null is returned.

reduce(T combine(T previous, T element)) → Future<RawSocketEvent>
inherited

Reduces a sequence of values by repeatedly applying combine.

setOption(SocketOption option, bool enabled) → bool

Use setOption to customize the RawSocket. See SocketOption for available options.…

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.READ_CLOSED event.

singleWhere(bool test(T element)) → Future<RawSocketEvent>
inherited

Finds the single element in this stream matching test.…

skip(int count) → Stream<RawSocketEvent>
inherited

Skips the first count data events from this stream.…

skipWhile(bool test(T element)) → Stream<RawSocketEvent>
inherited

Skip data events from this stream while they are matched by test.…

take(int count) → Stream<RawSocketEvent>
inherited

Provides at most the first n values of this stream.…

takeWhile(bool test(T element)) → Stream<RawSocketEvent>
inherited

Forwards data events while test is successful.…

timeout(Duration timeLimit, {void onTimeout(EventSink sink)}) → Stream
inherited

Creates a new stream with the same events as this stream.…

toList() → Future<List<RawSocketEvent>>
inherited

Collects the data of this stream in a List.

toSet() → Future<Set<RawSocketEvent>>
inherited

Collects the data of this stream in a Set.…

transform(StreamTransformer<RawSocketEvent> streamTransformer) → Stream
inherited

Chains this stream as the input of the provided StreamTransformer.…

inherited

Creates a new stream from this stream that discards some data events.…

write(List<int> buffer, [int offset, int count]) → int

Writes up to count bytes of the buffer from offset 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.…
