Meziantou.FrameworkWorkerGlobalScope Class
The global object of a worker (https://html.spec.whatwg.org/multipage/workers.html#the-workerglobalscope-common-interface): a DedicatedWorkerGlobalScope or a SharedWorkerGlobalScope. A worker runs its own event loop on its own thread, and its scripts run in the realm of its own script engine (ScriptEngine.CreateWorkerScriptEngine): the members of a worker global scope must be used on the thread of the worker.

Properties
| Name | Description |
|---|---|
| CrossOriginIsolated | https://html.spec.whatwg.org/multipage/webappapis.html#dom-crossoriginisolated: a dedicated worker has the cross-origin isolated capability of its owner (except a worker created from a data: URL); a shared worker is isolated when its embedder policy is compatible with cross-origin isolation (https://html.spec.whatwg.org/multipage/workers.html#run-a-worker). |
| Fonts | The font source of the worker (https://drafts.csswg.org/css-font-loading/#font-source): the font faces created by the scripts of the worker and added to the set, which the text of its OffscreenCanvas objects uses once they are loaded. A worker has no CSS-connected font face. |
| IsSecureContext | https://html.spec.whatwg.org/multipage/webappapis.html#dom-issecurecontext: the creator of the worker is a secure context, and the URL of the worker is potentially trustworthy (or a data: or blob: URL). |
| Location | https://html.spec.whatwg.org/multipage/workers.html#dom-workerglobalscope-location |
| Name | Gets the name of the worker (https://html.spec.whatwg.org/multipage/workers.html#concept-workerglobalscope-name). |
| Navigator | https://html.spec.whatwg.org/multipage/workers.html#dom-worker-navigator |
| OnError | Gets or sets the event handler of the error event. |
| OnLanguageChange | Gets or sets the event handler of the languagechange event. |
| OnOffline | Gets or sets the event handler of the offline event. |
| OnOnline | Gets or sets the event handler of the online event. |
| OnRejectionHandled | Gets or sets the event handler of the rejectionhandled event. |
| OnUnhandledRejection | Gets or sets the event handler of the unhandledrejection event. |
| Origin | https://html.spec.whatwg.org/multipage/webappapis.html#dom-origin |
| Self | https://html.spec.whatwg.org/multipage/workers.html#dom-workerglobalscope-self |
| TrustedTypes | https://w3c.github.io/trusted-types/dist/spec/#dom-windoworworkerglobalscope-trustedtypes: the trusted type policy factory of the worker. Trusted Types are enforced by the require-trusted-types-for and trusted-types directives of the CSP list of the worker (the policies of the response of its script, or the ones of its creator for a worker whose URL is a local scheme). |
