Interface GeolocationResult

All Superinterfaces:

Serializable

All Known Implementing Classes:

GeolocationError, GeolocationPending, GeolocationPosition

public sealed interface GeolocationResult
extends Serializable
permits GeolocationPending (not exhaustive)

The value held by GeolocationWatcher.positionSignal() — a successful reading, an error, or the initial "waiting for first reading" state. Always exactly one of:

• GeolocationPending — initial state, before the browser has reported anything.
• GeolocationPosition — a successful reading.
• GeolocationError — the browser reported an error.

The sealed hierarchy supports exhaustive pattern matching:

 switch (watcher.positionSignal().get()) {
 case GeolocationPending p -> showSpinner();
 case GeolocationPosition pos -> map.setCenter(pos.coords());
 case GeolocationError err -> showError(err.errorCode());
 }
