IsolateChannel<T> class

A StreamChannel that communicates over a ReceivePort/SendPort pair, presumably with another isolate.

The remote endpoint doesn't necessarily need to be running an IsolateChannel. This can be used with any two ports, although the StreamChannel semantics mean that this class will treat them as being paired (for example, closing the sink will cause the stream to stop emitting events).

The underlying isolate ports have no notion of closing connections. This means that stream won't close unless sink is closed, and that closing sink won't cause the remote endpoint to close. Users should take care to ensure that they always close the sink of every IsolateChannel they use to avoid leaving dangling ReceivePorts.

Connects to a remote channel that was created with IsolateChannel.connectSend. [...]
factory
IsolateChannel.connectSend(SendPort sendPort)
Connects to a remote channel that was created with IsolateChannel.connectReceive. [...]

Methods

cast<S>() StreamChannel<S>
Returns a copy of this with the generic type coerced to S. [...]
inherited
changeSink(StreamSink<T> change(StreamSink<T> sink)) StreamChannel<T>
Returns a copy of this with sink replaced by change's return value.
inherited
changeStream(Stream<T> change(Stream<T> stream)) StreamChannel<T>
Returns a copy of this with stream replaced by change's return value.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
pipe(StreamChannel<T> other) → void
Connects this to other, so that any values emitted by either are sent directly to the other.
inherited
toString() String
Returns a string representation of this object.
inherited
transform<S>(StreamChannelTransformer<S, T> transformer) StreamChannel<S>
Transforms this using transformer. [...]
inherited
transformSink(StreamSinkTransformer<T, T> transformer) StreamChannel<T>
Transforms only the sink component of this using transformer.
inherited
transformStream(StreamTransformer<T, T> transformer) StreamChannel<T>
