HarmonyOS开发实战：ArkTS接口绑定

场景介绍

通过napi_wrap将ArkTS对象与Native的C++对象绑定，后续操作时再通过napi_unwrap将ArkTS对象绑定的C++对象取出，并对其进行操作。

使用示例

1. 接口声明、编译配置以及模块注册

   接口声明

   // index.d.ts
   export class MyObject {
      constructor(arg: number);
      plusOne: () => number;
   
      public get value();
      public set value(newVal: number);
   }

   编译配置

   // CMakeLists.txt
   # the minimum version of CMake.
   cmake_minimum_required(VERSION 3.4.1)
   project(object_wrap)
   
   set(NATIVERENDER_ROOT_PATH ${CMAKE_CURRENT_SOURCE_DIR})
   
   include_directories(${NATIVERENDER_ROOT_PATH}
                       ${NATIVERENDER_ROOT_PATH}/include)
   
   add_definitions("-DLOG_DOMAIN=0x0000")
   add_definitions("-DLOG_TAG=\"testTag\"")
   
   add_library(object_wrap SHARED object_wrap.cpp)
   target_link_libraries(object_wrap PUBLIC libace_napi.z.so libhilog_ndk.z.so)

   模块注册

   // object_wrap.cpp
   class MyObject {
    public:
     static napi_value Init(napi_env env, napi_value exports);
     static void Destructor(napi_env env, void* nativeObject, void* finalize_hint);
   
    private:
     explicit MyObject(double value_ = 0);
     ~MyObject();
   
     static napi_value New(napi_env env, napi_callback_info info);
     static napi_value GetValue(napi_env env, napi_callback_info info);
     static napi_value SetValue(napi_
