RawSocket abstract 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.
- Implements
- Implemented by
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.
Constructors
Properties
- address → InternetAddress read-only
-
Returns the
InternetAddress
used to connect this socket. - 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.
- 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. - first → Future<RawSocketEvent> read-only, inherited
-
Returns the first element of the stream.
- hashCode → int read-only, inherited
-
The hash code for this object.
- isBroadcast → bool read-only, inherited
-
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.
- runtimeType → Type read-only, inherited
-
A representation of the runtime type of the object.
- single → Future<RawSocketEvent> read-only, inherited
-
Returns the single element.
Operators
- operator ==(
other) → bool inherited -
The equality operator.
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 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.
- 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. - 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(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<E>(
Stream<E> convert(T event)) → Stream<E> inherited -
Creates a new stream with the events of a stream per original event.
- asyncMap<E>(
dynamic convert(T event)) → Stream<E> inherited -
Creates a new stream with each data event of this stream asynchronously mapped to a new event.
- 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<E>(
[E futureValue ]) → Future<E> inherited -
Discards all data on the stream, but signals when it's done or an error occurred.
- elementAt(
int index) → Future<RawSocketEvent> inherited -
Returns the value of the
index
th data event of this stream. - every(
bool test(T element)) → Future<bool> inherited -
Checks whether
test
accepts all elements provided by this stream. - expand<S>(
Iterable<S> convert(T value)) → Stream<S> 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<S>(
S initialValue, S combine(S previous, T element)) → Future<S> 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<S>(
S convert(T event)) → Stream<S> inherited -
Creates a new stream that converts each element of this stream to a new value using the
convert
function. - noSuchMethod(
Invocation invocation) → dynamic inherited -
Invoked when a non-existent method or property is accessed.
- pipe(
StreamConsumer<RawSocketEvent> streamConsumer) → Future inherited -
Pipe the events of this stream into
streamConsumer
. - reduce(
RawSocketEvent combine(T previous, T element)) → Future<RawSocketEvent> inherited -
Reduces a sequence of values by repeatedly applying
combine
. - 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
count
data events of this stream. - takeWhile(
bool test(T element)) → Stream<RawSocketEvent> inherited -
Forwards data events while
test
is successful. - timeout(
Duration timeLimit, { void onTimeout(EventSink<T> sink) }) → Stream<RawSocketEvent> 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.
- toString(
) → String inherited -
Returns a string representation of this object.
- transform<S>(
StreamTransformer<RawSocketEvent, S> streamTransformer) → Stream<S> inherited -
Chains this stream as the input of the provided StreamTransformer.
- where(
bool test(T event)) → Stream<RawSocketEvent> inherited -
Creates a new stream from this stream that discards some data events.
