Package Exports

multi-buffer-data-view

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (multi-buffer-data-view) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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.
