# CallbackScope
|
||
|
|
|
||
|
|
There are cases (for example, resolving promises) where it is necessary to have
|
||
|
|
the equivalent of the scope associated with a callback in place when making
|
||
|
|
certain N-API calls.
|
||
|
|
|
||
|
|
## Methods
|
||
|
|
|
||
|
|
### Constructor
|
||
|
|
|
||
|
|
Creates a new callback scope on the stack.
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Napi::CallbackScope::CallbackScope(napi_env env, napi_callback_scope scope);
|
||
|
|
```
|
||
|
|
|
||
|
|
- `[in] env`: The environment in which to create the `Napi::CallbackScope`.
|
||
|
|
- `[in] scope`: The pre-existing `napi_callback_scope` or `Napi::CallbackScope`.
|
||
|
|
|
||
|
|
### Constructor
|
||
|
|
|
||
|
|
Creates a new callback scope on the stack.
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Napi::CallbackScope::CallbackScope(napi_env env, napi_async_context context);
|
||
|
|
```
|
||
|
|
|
||
|
|
- `[in] env`: The environment in which to create the `Napi::CallbackScope`.
|
||
|
|
- `[in] async_context`: The pre-existing `napi_async_context` or `Napi::AsyncContext`.
|
||
|
|
|
||
|
|
### Destructor
|
||
|
|
|
||
|
|
Deletes the instance of `Napi::CallbackScope` object.
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
virtual Napi::CallbackScope::~CallbackScope();
|
||
|
|
```
|
||
|
|
|
||
|
|
### Env
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Napi::Env Napi::CallbackScope::Env() const;
|
||
|
|
```
|
||
|
|
|
||
|
|
Returns the `Napi::Env` associated with the `Napi::CallbackScope`.
|
||
|
|
|
||
|
|
## Operator
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Napi::CallbackScope::operator napi_callback_scope() const;
|
||
|
|
```
|
||
|
|
|
||
|
|
Returns the N-API `napi_callback_scope` wrapped by the `Napi::CallbackScope`
|
||
|
|
object. This can be used to mix usage of the C N-API and node-addon-api.
