final, inherited

hashCode → int

The hash code for this object.

no setter, inherited

isConnected → bool

Returns true if the Worker is connected i.e., it has a valid Channel. Returns false otherwise.

Methods

autoRelease(List<Releasable?> instances) → void

The autoRelease method is used to register a set of Releasable instances that will be automatically released when this instance becomes unreachable. Please note that this mechanism is based on Dart's Finalizer feature which makes no guarantee that it will ever be called. Depending on instance dependencies and their relationship with the internal Finalizer instance, it may even never be called. For instance, make sure this is never passed to autoRelease as this will create a cyclic graph of dependencies that will prevent finalization to happen.

inherited

getLocalWorker([ExceptionManager? exceptionManager]) → LocalWorker<QuantizeService>

Available on QuantizeService, provided by the $QuantizeServiceLocalWorkerExt extension

getSharedChannel() → Channel?

Shared Channel that can be used to communicate with the worker.

inherited

getStartArgs() → List?

The Worker's start arguments.

getStats() → WorkerStat

Worker statistics.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

quantize(List<int> argbs, int maxColors) → Future<QuantizerResult>

inherited

release() → void

The release method must be overriden in derived classes to clean up any resources they use. Implementations should not throw and must call super.release() in a finally block. If a derived class defines Releasable fields, these fields should be released of in this method. Note for implementers: it should be safe to call this method several times.

inherited

send(int command, {List args = const [], CancelationToken? token, bool inspectRequest = false, bool inspectResponse = false}) → Future

Sends a workload to the worker.

inherited

start() → Future<Channel>

Creates a Channel and starts the worker using the _entryPoint.

inherited

stop() → void

Stops this worker.

inherited

stream(int command, {List args = const [], CancelationToken? token, bool inspectRequest = false, bool inspectResponse = false}) → Stream

Sends a streaming workload to the worker.

inherited

terminate([TaskTerminatedException? ex]) → void

Terminates this worker.

inherited

toString() → String

A string representation of this object.

inherited

track() → void

Implementations should call this method e.g. at construction time to make sure they will be trackable in debugging scenarios. See ReleasableTracker.enable for more information.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
