multi-buffer-data-view
A wrapper around the native DataView which can handle multiple ArrayBuffers.
![version](https://img.shields.io/npm/v/multi-buffer-data-view.svg?style=flat-square)
This module provides a wrapper around the native DataView. But instead of supporting only one ArrayBuffer as the backing memory the MultiBufferDataView
exported by this module can operate across multiple ArrayBuffers.
Usage
The multi-buffer-data-view
module is available on npm and can be installed as usual.
npm install multi-buffer-data-view
It exports only one class called MultiBufferDataView
which can be imported like this:
import { MultiBufferDataView } from 'multi-buffer-data-view';
A MultiBufferDataView
behaves almost like a native DataView with the notable exception that it can handle multiple ArrayBuffers.
const anArrayBuffer = new ArrayBuffer(23);
const anotherArrayBuffer = new ArrayBuffer(41);
new MultiBufferDataView([anArrayBuffer, anotherArrayBuffer]);
The little example above will create a MultiBufferDataView
which uses all 64 bytes that are available in the given ArrayBuffers. However it is also possible to limit the range of accessible bytes by providing a byteOffset
or a byteLength
as additional arguments.
new MultiBufferDataView([anArrayBuffer, anotherArrayBuffer], 12, 24);
When creating a MultiBufferDataView
with the parameters above it will only use the last 11 bytes of the first ArrayBuffer and the first 13 bytes of the second ArrayBuffer.
