BroadcastFrameClock

class BroadcastFrameClock(onNewAwaiters: () -> Unit?) : MonotonicFrameClock

A simple frame clock.

This implementation is intended for low-contention environments involving low total numbers of threads in a pool on the order of ~number of CPU cores available for UI recomposition work, while avoiding additional allocation where possible.

onNewAwaiters will be invoked whenever the number of awaiters has changed from 0 to 1.

Constructors

BroadcastFrameClock

common

fun BroadcastFrameClock(onNewAwaiters: () -> Unit? = null)

Functions

equals

common

open operator fun equals(other: Any?): Boolean

fold

common

open override fun <R> fold(initial: R, operation: (R, CoroutineContext.Element) -> R): R

get

common

open operator override fun <E : CoroutineContext.Element> get(key: CoroutineContext.Key<E>): E?

hashCode

common

open fun hashCode(): Int

minusKey

common

open override fun minusKey(key: CoroutineContext.Key<*>): CoroutineContext

plus

common

open operator fun plus(context: CoroutineContext): CoroutineContext

sendFrame

common

fun sendFrame(timeNanos: Long)

toString

common

open fun toString(): String

withFrameNanos

common

open suspend override fun <R> withFrameNanos(onFrame: (Long) -> R): R

Suspends until a new frame is requested, immediately invokes onFrame with the frame time in nanoseconds in the calling context of frame dispatch, then resumes with the result from onFrame.

Properties

common

val hasAwaiters: Boolean

key

common

open override val key: CoroutineContext.Key<*>
