multi-buffer-data-view

A wrapper around the native DataView which can handle multiple ArrayBuffers.

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.
