RawSocket class

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

RawSocket()

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>
The first element of the stream. [...]
read-only, inherited
hashCode → int
The hash code for this object. [...]
read-only, inherited
isBroadcast → bool
Whether this stream is a broadcast stream.
read-only, inherited
isEmpty → Future<bool>
Whether this stream contains any elements. [...]
read-only, inherited
last → Future<RawSocketEvent>
The last element of this stream. [...]
read-only, inherited
length → Future<int>
The number of elements in this stream. [...]
read-only, inherited
runtimeType → Type
A representation of the runtime type of the object.
read-only, inherited
single → Future<RawSocketEvent>
The single element of this stream. [...]

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. [...]
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.
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.readClosed event.
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. [...]
any(bool test(T element)) → Future<bool>
Checks whether test accepts any element provided by this stream. [...]
inherited
asBroadcastStream({void onListen(StreamSubscription<T> subscription), void onCancel(StreamSubscription<T> subscription) }) → Stream<RawSocketEvent>
Returns a multi-subscription stream that produces the same events as this. [...]
inherited
asyncExpand<E>(Stream<E> convert(T event)) → Stream<E>
Transforms each element into a sequence of asynchronous events. [...]
inherited
asyncMap<E>(FutureOr<E> convert(T event)) → Stream<E>
Creates a new stream with each data event of this stream asynchronously mapped to a new event. [...]
inherited
cast<R>() → Stream<R>
Adapt this stream to be a Stream<R>. [...]
inherited
contains(Object needle) → Future<bool>
Returns whether needle occurs in the elements provided by this stream. [...]
inherited
distinct([bool equals(T previous, T next) ]) → Stream<RawSocketEvent>
Skips data events if they are equal to the previous data event. [...]
inherited
drain<E>([E futureValue ]) → Future<E>
Discards all data on the stream, but signals when it's done or an error occurred. [...]
inherited
elementAt(int index) → Future<RawSocketEvent>
Returns the value of the indexth data event of this stream. [...]
inherited
every(bool test(T element)) → Future<bool>
Checks whether test accepts all elements provided by this stream. [...]
inherited
expand<S>(Iterable<S> convert(T element)) → Stream<S>
Transforms each element of this stream into a sequence of elements. [...]
inherited
firstWhere(bool test(T element), { RawSocketEvent orElse() }) → Future<RawSocketEvent>
Finds the first element of this stream matching test. [...]
inherited
fold<S>(S initialValue, S combine(S previous, T element)) → Future<S>
Combines a sequence of values by repeatedly applying combine. [...]
inherited
forEach(void action(T element)) → Future
Executes action on each element of the stream. [...]
inherited
handleError(Function onError, { bool test(dynamic error) }) → Stream<RawSocketEvent>
Creates a wrapper Stream that intercepts some errors from this stream. [...]
inherited
join([String separator = "" ]) → Future<String>
Combines the string representation of elements into a single string. [...]
inherited
lastWhere(bool test(T element), { RawSocketEvent orElse() }) → Future<RawSocketEvent>
Finds the last element in this stream matching test. [...]
inherited
listen(void onData(T event), { Function onError, void onDone(), bool cancelOnError }) → StreamSubscription<RawSocketEvent>
Adds a subscription to this stream. [...]
inherited
map<S>(S convert(T event)) → Stream<S>
Transforms each element of this stream into a new stream event. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
pipe(StreamConsumer<RawSocketEvent> streamConsumer) → Future
Pipes the events of this stream into streamConsumer. [...]
inherited
reduce(RawSocketEvent combine(T previous, T element)) → Future<RawSocketEvent>
Combines a sequence of values by repeatedly applying combine. [...]
inherited
singleWhere(bool test(T element), { RawSocketEvent orElse() }) → Future<RawSocketEvent>
Finds the single element in this stream matching test. [...]
inherited
skip(int count) → Stream<RawSocketEvent>
Skips the first count data events from this stream. [...]
inherited
skipWhile(bool test(T element)) → Stream<RawSocketEvent>
Skip data events from this stream while they are matched by test. [...]
inherited
take(int count) → Stream<RawSocketEvent>
Provides at most the first count data events of this stream. [...]
inherited
takeWhile(bool test(T element)) → Stream<RawSocketEvent>

inherited
timeout(Duration timeLimit, { void onTimeout(EventSink<T> sink) }) → Stream<RawSocketEvent>

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

inherited
toString() → String
Returns a string representation of this object.
inherited
transform<S>(StreamTransformer<RawSocketEvent, S> streamTransformer) → Stream<S>
Applies a StreamTransformer to the current stream. [...]
inherited
where(bool test(T event)) → Stream<RawSocketEvent>
Creates a new stream from this stream that discards some elements. [...]
inherited

Operators

operator ==(dynamic other) → bool
The equality operator. [...]

Static Methods

connect(dynamic host, int port, { dynamic sourceAddress, Duration timeout }) → 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. [...]
