Class [Napi::Array][] inherits from class Napi::Object.
Arrays are native representations of JavaScript Arrays. Napi::Array is a wrapper
around napi_value representing a JavaScript Array.
Napi::TypedArray and Napi::ArrayBuffer correspond to JavaScript data
types such as Napi::Int32Array and Napi::ArrayBuffer, respectively,
that can be used for transferring large amounts of data from JavaScript to the
native side. An example illustrating the use of a JavaScript-providedArrayBuffer in native code is available here.
Napi::Array::Array();
Returns an empty array.
If an error occurs, a Napi::Error will be thrown. If C++ exceptions are not
being used, callers should check the result of Env::IsExceptionPending before
attempting to use the returned value.
Napi::Array::Array(napi_env env, napi_value value);
[in] env - The environment in which to create the array.[in] value - The primitive to wrap.Returns a Napi::Array wrapping a napi_value.
If an error occurs, a Napi::Error will get thrown. If C++ exceptions are not
being used, callers should check the result of Env::IsExceptionPending before
attempting to use the returned value.
static Napi::Array Napi::Array::New(napi_env env);
[in] env - The environment in which to create the array.Returns a new Napi::Array.
If an error occurs, a Napi::Error will get thrown. If C++ exceptions are not
being used, callers should check the result of Env::IsExceptionPending before
attempting to use the returned value.
static Napi::Array Napi::Array::New(napi_env env, size_t length);
[in] env - The environment in which to create the array.[in] length - The length of the array.Returns a new Napi::Array with the given length.
If an error occurs, a Napi::Error will get thrown. If C++ exceptions are not
being used, callers should check the result of Env::IsExceptionPending before
attempting to use the returned value.
uint32_t Napi::Array::Length() const;
Returns the length of the array.
Note:
This can execute JavaScript code implicitly according to JavaScript semantics.
If an error occurs, a Napi::Error will get thrown. If C++ exceptions are not
being used, callers should check the result of Env::IsExceptionPending before
attempting to use the returned value.
