Partition an ArrayBuffer into multiple TypedArray views efficiently.
npm install @ain1084/array-buffer-partitioner
Partition an ArrayBuffer into multiple TypedArray views efficiently, while handling complex memory layouts and ensuring optimal alignment for better access performance.
@ain1084/array-buffer-partitioner is a utility library for creating multiple TypedArray views on a single ArrayBuffer or SharedArrayBuffer. This allows various data types to be efficiently placed within a single buffer. The library automatically adjusts each TypedArray’s byteOffset to prevent errors that can occur during view creation.
- Create multiple TypedArray views from a single ArrayBuffer or SharedArrayBuffer.
- Efficient memory partitioning without manual offset calculations.
Install the library via npm:
``sh`
npm i @ain1084/array-buffer-partitioner
Import the createArrayBufferViews function to partition an ArrayBuffer or SharedArrayBuffer into multiple views:
`typescript
import { createArrayBufferViews } from '@ain1084/array-buffer-partitioner';
const views = createArrayBufferViews(ArrayBuffer, {
data: [Float32Array, 1024],
index: [Uint32Array, 1],
flag: [Uint8Array, 1]
});
console.log(views.data.length); // 1024
console.log(views.data.byteOffset); // 0
console.log(views.index.length); // 1
console.log(views.flag.length); // 1
console.log(views.flag.byteOffset); // 4100
console.log(views.data.buffer.byteLength); // 4104
`
For detailed API documentation, please refer to the GitHub Pages documentation.
Creates multiple TypedArray views on a single ArrayBuffer or SharedArrayBuffer.
#### Parameters
- BufferType ({ new(size: number): ArrayBuffer | SharedArrayBuffer }): The constructor for the buffer, either ArrayBuffer or SharedArrayBuffer.config
- (Record): An object specifying the desired views. Each key represents the name of the view, and the value is a tuple where:TypedArray
- The first element is the class name (e.g., Float32Array, Uint32Array`).
- The second element is the number of elements for that view.
#### Returns
An object containing the views, with each key corresponding to the provided configuration.
