• MountingManager

  MountingManager(ViewManagerRegistry viewManagerRegistry, MountingManager.MountItemExecutor mountItemExecutor)

Method Detail

• startSurface

  @AnyThread() SurfaceMountingManager startSurface(int surfaceId, ThemedReactContext reactContext, @Nullable() View rootView)

  Starts surface without attaching the view. All view operations executed against that surfacewill be queued until the view is attached.

• attachRootView

  @AnyThread() void attachRootView(int surfaceId, @NonNull() View rootView, ThemedReactContext themedReactContext)

• stopSurface

  @AnyThread() void stopSurface(int surfaceId)

• getSurfaceManager

  @Nullable() SurfaceMountingManager getSurfaceManager(int surfaceId)

• getSurfaceManagerEnforced

  @NonNull() SurfaceMountingManager getSurfaceManagerEnforced(int surfaceId, String context)

• surfaceIsStopped

   boolean surfaceIsStopped(int surfaceId)

• isWaitingForViewAttach

   boolean isWaitingForViewAttach(int surfaceId)

• getSurfaceManagerForView

  @Nullable() SurfaceMountingManager getSurfaceManagerForView(int reactTag)

  Get SurfaceMountingManager associated with a ReactTag. Unfortunately, this requires lookupsover N maps, where N is the number of active or recently-stopped Surfaces. Each lookup willcost `log(M)` operations where M is the number of reactTags in the surface, so the total costper lookup is `O(N * log(M))`.

  To mitigate this cost, we attempt to keep track of the "most recent" SurfaceMountingManagerand do lookups in it first. For the vast majority of use-cases, except for events or operationssent to off-screen surfaces, or use-cases where multiple surfaces are visible and interactable,this will reduce the lookup time to `O(log(M))`. Someone smarter than me could probably figureout an amortized time.

• getSurfaceManagerForViewEnforced

  @NonNull()@AnyThread() SurfaceMountingManager getSurfaceManagerForViewEnforced(int reactTag)

• getViewExists

   boolean getViewExists(int reactTag)

• receiveCommand

  @Deprecated() void receiveCommand(int surfaceId, int reactTag, int commandId, @Nullable() ReadableArray commandArgs)

• receiveCommand

   void receiveCommand(int surfaceId, int reactTag, @NonNull() String commandId, @Nullable() ReadableArray commandArgs)

• sendAccessibilityEvent

   void sendAccessibilityEvent(int surfaceId, int reactTag, int eventType)

  Send an accessibility eventType to a Native View. eventType is any valid `AccessibilityEvent.X`value.

  Why accept `-1` SurfaceId? Currently there are calls to UIManager.sendAccessibilityEventwhich is a legacy API and accepts only reactTag. We will have to investigate and migrate awayfrom those calls over time.

  Parameters:

  surfaceId - that identifies the surface or -1 to temporarily support backwardcompatibility.

  reactTag - that identifies the react Tag of the view.

  eventType - that identifies Android eventType.

• updateProps

  @UiThread() void updateProps(int reactTag, @Nullable() ReadableMap props)

• clearJSResponder

  @UiThread() void clearJSResponder()

  Clears the JS Responder specified by setJSResponder. After thismethod is called, all the touch events are going to be handled by JS.

• getEventEmitter

  @AnyThread()@Nullable() EventEmitterWrapper getEventEmitter(int surfaceId, int reactTag)

• measure

  @AnyThread() long measure(@NonNull() ReactContext context, @NonNull() String componentName, @NonNull() ReadableMap localData, @NonNull() ReadableMap props, @NonNull() ReadableMap state, float width, @NonNull() YogaMeasureMode widthMode, float height, @NonNull() YogaMeasureMode heightMode, @Nullable() Array<float> attachmentsPositions)

  Measure a component, given localData, props, state, and measurement information. This needs toremain here for now - and not in SurfaceMountingManager - because sometimes measures are madeoutside of the context of a Surface; especially from C++ before StartSurface is called.

• measureMapBuffer

  @AnyThread() long measureMapBuffer(@NonNull() ReactContext context, @NonNull() String componentName, @NonNull() MapBuffer localData, @NonNull() MapBuffer props, @Nullable() MapBuffer state, float width, @NonNull() YogaMeasureMode widthMode, float height, @NonNull() YogaMeasureMode heightMode, @Nullable() Array<float> attachmentsPositions)

  Measure a component, given localData, props, state, and measurement information. This needs toremain here for now - and not in SurfaceMountingManager - because sometimes measures are madeoutside of the context of a Surface; especially from C++ before StartSurface is called.

• initializeViewManager

   void initializeViewManager(String componentName)
