Package limn.concurrent

package limn.concurrent

The threading model and the async API on top of it: a single UI thread that every widget mutation is confined to, reached through Ui, with Ui.post(java.lang.Runnable) to cross onto it, Ui.async(java.util.function.Supplier<T>) for future-shaped work, and Ui.work(limn.concurrent.Work.Body<T>) for a cancellable Work that reports Progress and is held as a Job. The backend installs the UiRuntime at startup and drains its queue once per frame.

Confinement is checked, not advisory: a widget mutated off the UI thread throws, and every success, failure and progress callback this package delivers runs where touching widgets is legal.

Class	Description
Job	A started piece of background work, as seen by whoever asked for it.
Progress	The only handle a background body has on the outside world while it runs: it can ask whether it has been cancelled, and it can say how far it has got.
Ui	Static facade over the toolkit's UiRuntime, Limn's first-class async API.
UiRuntime	The concurrency runtime behind Ui: a single UI thread fed by a thread-safe (MPSC) task queue, plus a worker pool for the application's heavy background work.
UiRuntime.Waker	Wakes the native event loop when work is posted from another thread.
Work<T>	A description of background work, built up and then started once.
Work.Body<T>	The background body.
