在想要在某些 Objective-C 代码上按名称引用类、使用接口生成器 XIB 和情节提要文件时,或者使用 Objective-C 序列化设置 ((例如 NSCoder 在使用) 时),通常会使用上述方法。 C# 复制 // // This exposes the C# class _MySampleView as the Objective-C MyView // [Export ("MyView")] public class ...
InvalidArgument Invalid Argument. Parameter is invalid Cause: The format of a parameter is invalid. Solution: Make sure that the parameters are in the valid format before you call the API operation. For more information, see List of operations by function. The callback signature version is ...
The `is` and `as` operators test the type of an object. The `typeof` keyword returns the type of a variable. Casts try to convert an object to a variable of a different type.
The Predicate parameter is used whenever an algorithm expects a function object that when applied to the result of dereferencing the corresponding iterator returns a value testable as true. In other words, if an algorithm takes Predicate pred as its argument and first as its iterator argument, it...
The abstract operation OrdinaryOwnPropertyKeys takes argument O (an Object). It performs the following steps when called: Let keys be a new empty List. For each own property key P of O such that P is an array index, in ascending numeric index order, do a. Add P as the last element ...

在ArkTS层往C++层注册一个object或function,C++层可以按需往这个回调上进行扔消息同步到上层应用么,请提供示例?在注册object或function时,napi_env是否可以被长时持有?扔消息同步到上层应用时,是否需要在特定线程 Cmake编译时如何显示不同级别的日志信息 ArkTS侧如何释放绑定的C++侧对象 Native侧如何获取ArkTS侧的...
You then use the helper function, helperSimulateTDOA, to simulate TDOA measurements from the objects. The helper function allows you to specify the measurement accuracy in the TDOA. You use a measurement accuracy of 100 nanoseconds to represent timing inaccuracy in the clocks as well as TDOA esti...
The code uses the closePorts local function, which closes multiple ports. This results in an "Illegal argument in isolate message: (object is a ReceivePort)" error. The same error will occur even if this function is not used anywhere at all. ...
