Functions

canCoalesce

open fun canCoalesce(): Boolean

coalesce

open fun coalesce(otherEvent: ContentSizeChangeEvent): ContentSizeChangeEvent

Given two events, coalesce them into a single event that will be sent to JS instead of two separate events. By default, just chooses the one the is more recent, or this if timestamps are the same.

dispatch

open fun ~~dispatch~~(rctEventEmitter: RCTEventEmitter)

Dispatch this event to JS using the given event emitter. Compatible with old and new renderer. Instead of using this or dispatchModern, it is recommended that you simply override `getEventData`.

dispatchModern

open fun dispatchModern(rctEventEmitter: RCTModernEventEmitter)

Dispatch this event to JS using a V2 EventEmitter. If surfaceId is not -1 and `getEventData` is non-null, this will use the RCTModernEventEmitter API. Otherwise, it falls back to the old-style dispatch function. For Event classes that need to do something different, this method can always be overridden entirely, but it is not recommended.

getCoalescingKey

open fun getCoalescingKey(): Short

getEventAnimationDriverMatchSpec

open fun getEventAnimationDriverMatchSpec(): Event.EventAnimationDriverMatchSpec

getEventName

open override fun getEventName(): String

getSurfaceId

fun getSurfaceId(): Int

getTimestampMs

fun getTimestampMs(): Long

getUniqueID

open fun getUniqueID(): Int

getViewTag

fun getViewTag(): Int

onDispose

open fun onDispose()

Called when the EventDispatcher is done with an event, either because it was dispatched or because it was coalesced with another Event.
