Key-Value Store Module

This repository contains an Android project with a sample app and a reusable module, key-value-store, which provides functionality to store, retrieve, and delete key-value pairs of different data types. The main interface for accessing this functionality is through the ObjectCacher class.

Overview

The key-value-store module offers a simple way to cache objects by associating them with a string key, allowing you to store and retrieve various data types (e.g., Int, Boolean, String, and general Any types) persistently across app sessions.

Setup

1. Installation

Clone the repository and add the key-value-store module to your Android project.

2. Initialization

Before using any of the caching functions, you need to initialize the ObjectCacher:

ObjectCacher.initialize(context)

3. Usage

Once initialized, you can use the various methods to store, fetch, and delete data by key.

Methods

The following methods are available in ObjectCacher:

General Object Storage

• storeValue(key: String, value: Any): Boolean Stores a value of any type.
• fetchValue(key: String): Any? Fetches a previously stored value.
• deleteValue(key: String) Deletes a stored value.

Type-Specific Storage

The module also provides methods to store and retrieve values of specific types, including Int, Boolean, and String.

• storeInt(key: String, value: Int): Boolean Stores an integer value.
• fetchInt(key: String): Int? Fetches an integer value.
• deleteInt(key: String): Boolean Deletes a stored integer value.
• storeBoolean(key: String, value: Boolean): Boolean Stores a boolean value.
• fetchBoolean(key: String): Boolean? Fetches a boolean value.
• deleteBoolean(key: String): Boolean Deletes a stored boolean value.
• storeString(key: String, value: String): Boolean Stores a string value.
• fetchString(key: String): String? Fetches a string value.
• deleteString(key: String): Boolean Deletes a stored string value.

Example

// Initialize the ObjectCacher
ObjectCacher.initialize(context)

// Store values
ObjectCacher.storeString("username", "JohnDoe")
ObjectCacher.storeInt("userId", 12345)
ObjectCacher.storeBoolean("isLoggedIn", true)

// Fetch values
val username = ObjectCacher.fetchString("username")
val userId = ObjectCacher.fetchInt("userId")
val isLoggedIn = ObjectCacher.fetchBoolean("isLoggedIn")

// Delete values
ObjectCacher.deleteString("username")
ObjectCacher.deleteInt("userId")
ObjectCacher.deleteBoolean("isLoggedIn")

Notes

Ensure that ObjectCacher is initialized before calling any storage methods; otherwise, the methods will return default values (false, null, etc.). The module is designed to handle different data types separately to ensure type safety.
