Class Overview

Animation backend delegate for animation backends that implement AnimationBackendDelegateWithInactivityCheck.InactivityListener. After a certain inactivity period (default = #INACTIVITY_THRESHOLD_MS, onInactive() will be called. This can for example be used to drop caches if needed. New instances can be created with createForBackend(AnimationBackend, MonotonicClock, ScheduledExecutorService).
