-# Object Wrap
-
-The `Napi::ObjectWrap` class is used to bind the lifetime of C++ code to a
-JavaScript object. Once bound, each time an instance of the JavaScript object
-is created, an instance of the C++ class will also be created. When a method
-is called on the JavaScript object which is defined as an InstanceMethod, the
-corresponding C++ method on the wrapped C++ class will be invoked.
-
-In order to create a wrapper it's necessary to extend the
-`Napi::ObjectWrap`class which contains all the plumbing to connect JavaScript code
-with a C++ object. Classes extending `Napi::ObjectWrap` can be instantiated from
-JavaScript using the **new** operator, and their methods can be directly invoked
-from JavaScript. The **wrap** word refers to a way of grouping methods and state
-of the class because it will be necessary write custom code to bridge each of
-your C++ class methods.
-
-## Example
-
-```cpp
-#include <napi.h>
-
-class Example : public Napi::ObjectWrap<Example> {
-  public:
-    static Napi::Object Init(Napi::Env env, Napi::Object exports);
-    Example(const Napi::CallbackInfo &info);
-
-  private:
-    static Napi::FunctionReference constructor;
-    double _value;
-    Napi::Value GetValue(const Napi::CallbackInfo &info);
-    Napi::Value SetValue(const Napi::CallbackInfo &info);
-};
-
-Napi::Object Example::Init(Napi::Env env, Napi::Object exports) {
-    // This method is used to hook the accessor and method callbacks
-    Napi::Function func = DefineClass(env, "Example", {
-        InstanceMethod("GetValue", &Example::GetValue),
-        InstanceMethod("SetValue", &Example::SetValue)
-    });
-
-    // Create a peristent reference to the class constructor. This will allow
-    // a function called on a class prototype and a function
-    // called on instance of a class to be distinguished from each other.
-    constructor = Napi::Persistent(func);
-    // Call the SuppressDestruct() method on the static data prevent the calling
-    // to this destructor to reset the reference when the environment is no longer
-    // available.
-    constructor.SuppressDestruct();
-    exports.Set("Example", func);
-    return exports;
-}
-
-Example::Example(const Napi::CallbackInfo &info) : Napi::ObjectWrap<Example>(info) {
-    Napi::Env env = info.Env();
-    // ...
-    Napi::Number value = info[0].As<Napi::Number>();
-    this->_value = value.DoubleValue();
-}
-
-Napi::FunctionReference Example::constructor;
-
-Napi::Value Example::GetValue(const Napi::CallbackInfo &info){
-    Napi::Env env = info.Env();
-    return Napi::Number::New(env, this->_value);
-}
-
-Napi::Value Example::SetValue(const Napi::CallbackInfo &info){
-    Napi::Env env = info.Env();
-    // ...
-    Napi::Number value = info[0].As<Napi::Number>();
-    this->_value = value.DoubleValue();
-    return this->GetValue(info);
-}
-
-// Initialize native add-on
-Napi::Object Init (Napi::Env env, Napi::Object exports) {
-    Example::Init(env, exports);
-    return exports;
-}
-
-// Register and initialize native add-on
-NODE_API_MODULE(NODE_GYP_MODULE_NAME, Init)
-```
-
-The above code can be used from JavaScript as follows:
-
-```js
-'use strict'
-
-const { Example } = require('bindings')('addon')
-
-const example = new Example(11)
-console.log(example.GetValue())
-// It prints 11
-example.SetValue(19)
-console.log(example.GetValue());
-// It prints 19
-```
-
-At initialization time, the `Napi::ObjectWrap::DefineClass()` method must be used
-to hook up the accessor and method callbacks. It takes a list of property
-descriptors, which can be constructed via the various static methods on the base
-class.
-
-When JavaScript code invokes the constructor, the constructor callback will create
-a new C++ instance and "wrap" it into the newly created JavaScript object.
-
-When JavaScript code invokes a method or a property accessor on the class the
-corresponding C++ callback function will be executed.
-
-For a wrapped object it could be difficult to distinguish between a function called
-on a class prototype and a function called on instance of a class. Therefore it is
-good practice to save a persistent reference to the class constructor. This allows
-the two cases to be distinguished from each other by checking the this object
-against the class constructor.
-
-## Methods
-
-### Constructor
-
-Creates a new instance of a JavaScript object that wraps native instance.
-
-```cpp
-Napi::ObjectWrap(const Napi::CallbackInfo& callbackInfo);
-```
-
-- `[in] callbackInfo`: The object representing the components of the JavaScript
-request being made.
-
-### Unwrap
-
-Retrieves a native instance wrapped in a JavaScript object.
-
-```cpp
-static T* Napi::ObjectWrap::Unwrap(Napi::Object wrapper);
-```
-
-* `[in] wrapper`: The JavaScript object that wraps the native instance.
-
-Returns a native instace wrapped in a JavaScript object. Given the
-Napi:Object, this allows a method to get a pointer to the wrapped
-C++ object and then reference fields, call methods, etc. within that class.
-In many cases calling Unwrap is not required, as methods can
-use the `this` field for ObjectWrap when running in a method on a
-class that extends ObjectWrap.
-
-### DefineClass
-
-Defnines a JavaScript class with constructor, static and instance properties and
-methods.
-
-```cpp
-static Napi::Function Napi::ObjectWrap::DefineClass(Napi::Env env,
-                                const char* utf8name,
-                                const std::initializer_list<PropertyDescriptor>& properties,

-```
-
-* `[in] env`: The environment in which to construct a JavaScript class.
-* `[in] utf8name`: Null-terminated string that represents the name of the
-JavaScript constructor function.
-* `[in] properties`: Initializer list of class property descriptor describing
-static and instance properties and methods of the class.
-See: [`Class property and descriptor`](class_property_descriptor.md).
-* `[in] data`: User-provided data passed to the constructor callback as `data`
-property of the `Napi::CallbackInfo`.
-
-Returns a `Napi::Function` representing the constructor function for the class.
-
-### DefineClass

-methods.

-                            const std::vector<PropertyDescriptor>& properties,
-                            void* data = nullptr);
-```
-
-* `[in] env`: The environment in which to construct a JavaScript class.
-* `[in] utf8name`: Null-terminated string that represents the name of the
-JavaScript constructor function.
-* `[in] properties`: Vector of class property descriptor describing static and
-instance properties and methods of the class.
-See: [`Class property and descriptor`](class_property_descriptor.md).
-* `[in] data`: User-provided data passed to the constructor callback as `data`
-property of the `Napi::CallbackInfo`.
-
-Returns a `Napi::Function` representing the constructor function for the class.
-
-### Finalize
-
-Provides an opportunity to run cleanup code that requires access to the `Napi::Env`
-before the wrapped native object instance is freed.  Override to implement.
