tos-bytebuffer v5.1.1

@tos/bytebuffer

@tos/bytebuffer is a lightweight and efficient library for managing binary data in TypeScript. It provides functionalities for reading, writing, queuing, and pooling buffers, along with support for generic network connectors (TCP, UDP, WebSocket).

Installation

To install the library via npm, run:

npm install @tos/bytebuffer

Features

• Efficient binary data manipulation with ByteBuffer.
• Buffer aggregation with QueueBuffer to reduce header overhead.
• Buffer pooling with ByteBufferPool to optimize memory allocation in high-frequency systems.
• Interface for generic network connectors supporting TCP, UDP, and WebSocket.

Usage Example

Here is a basic example of how to use the API provided by the library for binary buffer manipulation:

import { ByteBuffer, ByteBufferPool, QueueBuffer } from '@tos/bytebuffer';

// Initializing a ByteBuffer
const buffer = new ByteBuffer();
buffer.putInt32(1234).putString("Hello, ByteBuffer!");

const num = buffer.getInt32();
const str = buffer.getString();

console.log(num);  // 1234
console.log(str);  // "Hello, ByteBuffer!"

// Using ByteBufferPool to manage buffers
const pool = new ByteBufferPool();
const pooledBuffer = pool.acquire();
pooledBuffer.putFloat(3.14);
pool.release(pooledBuffer);

// Aggregating buffers with QueueBuffer
const queue = new QueueBuffer();
queue.enqueue(buffer);
queue.enqueue(pooledBuffer);

const combinedBuffer = queue.combine();

API

ByteBuffer

The main class for managing binary data. It provides methods for reading and writing various types of binary data.

• putInt32(value: number): ByteBuffer: Inserts a 32-bit integer into the buffer.
• getInt32(): number: Reads a 32-bit integer from the buffer.
• putString(value: string): ByteBuffer: Inserts a UTF-8 encoded string into the buffer.
• getString(): string: Reads a UTF-8 encoded string from the buffer.
• reset(): void: Resets the buffer's position for reuse.

QueueBuffer

Aggregates multiple binary buffers to reduce header overhead in packet transmissions.

• enqueue(buffer: ByteBuffer): void: Adds a buffer to the queue.
• combine(): ByteBuffer: Combines all enqueued buffers into a single buffer.

ByteBufferPool

Manages a pool of ByteBuffer instances to avoid frequent memory allocations, optimizing performance in high-load systems.

• acquire(): ByteBuffer: Retrieves a buffer from the pool or creates a new one if necessary.
• release(buffer: ByteBuffer): void: Returns a buffer to the pool, making it available for reuse.

Generic Connector Interface

Interface for creating generic network adapters that support TCP, UDP, and WebSocket.

• Supports socket creation and handling binary data packets.
• Integration with ByteBuffer for easy manipulation of network data.
