MainThread

actual typealias MainThread = androidx.annotation.MainThread

@Target(allowedTargets = [AnnotationTarget.FUNCTION, AnnotationTarget.PROPERTY_GETTER, AnnotationTarget.PROPERTY_SETTER, AnnotationTarget.CONSTRUCTOR, AnnotationTarget.ANNOTATION_CLASS, AnnotationTarget.CLASS, AnnotationTarget.VALUE_PARAMETER])

expect annotation class MainThread

Denotes that the annotated method should only be called on the main thread. If the annotated element is a class, then all methods in the class should be called on the main thread.

Example:

@MainThread
public void deliverResult(D data) { ... }

Note: Ordinarily, an app's main thread is also the UI thread. However, under special circumstances, an app's main thread might not be its UI thread; for more information, see Thread annotations.
