Variables

onmessage:Function

Is an EventHandler representing the code to be called when the message event is raised. These events are of type MessageEvent and will be called when the worker receives a message from the document that started it (i.e. from the Worker.postMessage method.)

Methods

postMessage (message:Dynamic, ?transfer:Array<Dynamic>):Void

Throws:

null

DOMError

Inherited Variables

Defined by WorkerGlobalScope

read onlyconsole:Console

Returns the Console associated with the worker.

read onlyindexedDB:Factory

read onlylocation:WorkerLocation

Returns the WorkerLocation associated with the worker. It is a specific location object, mostly a subset of the Location for browsing scopes, but adapted to workers.

read onlynavigator:WorkerNavigator

Returns the WorkerNavigator associated with the worker. It is a specific navigator object, mostly a subset of the Navigator for browsing scopes, but adapted to workers.

onclose:Function

Is an EventHandler representing the code to be called when the close event is raised.

onerror:EitherType<Event, String> ‑> String ‑> Int ‑> Int ‑> Dynamic ‑> Bool

Is an EventHandler representing the code to be called when the error event is raised.

onoffline:Function

Is an EventHandler representing the code to be called when the offline event is raised.

ononline:Function

Is an EventHandler representing the code to be called when the online event is raised.

read onlyperformance:Performance

Returns the Performance associated with the worker. It is a regular performance object, except that only a subset of its property and methods are available to workers.

read onlyself:WorkerGlobalScope

Returns a reference to the WorkerGlobalScope itself. Most of the time it is a specific scope like DedicatedWorkerGlobalScope,  SharedWorkerGlobalScope or ServiceWorkerGlobalScope.
