Class UIViewOperationQueue

java.lang.Object

com.facebook.react.uimanager.UIViewOperationQueue

public class UIViewOperationQueue
extends java.lang.Object

This class acts as a buffer for command executed on NativeViewHierarchyManager or on AnimationRegistry. It expose similar methods as mentioned classes but instead of executing commands immediately it enqueues those operations in a queue that is then flushed from UIManagerModule once JS batch of ui operations is finished. This is to make sure that we execute all the JS operation coming from a single batch a single loop of the main (UI) android looper. TODO(7135923): Pooling of operation objects TODO(5694019): Consider a better data structure for operations queue to save on allocations
