Flyweight Pattern in Go

Overview

This repository demonstrates the application of the Flyweight design pattern in Go. The project highlights how to minimize memory usage by sharing as much data as possible with other similar objects, showcasing flexibility and best practices in design patterns and unit testing.

Pattern Description

The Flyweight pattern is used to minimize memory usage by sharing data among similar objects. This is achieved by storing common data externally and passing it to the objects that need it. In this project, we have implemented the Flyweight pattern using a FlyweightFactory to manage and reuse flyweight objects.

Project Structure

• cmd/: Contains the application entry point (main.go), demonstrating the creation and usage of flyweights.
• pkg/flyweight/: Houses the Flyweight implementation.
  • flyweight.go: Defines the Flyweight interface.
  • concrete_flyweight.go: Implements the ConcreteFlyweight.
  • flyweight_factory.go: Implements the FlyweightFactory to create and manage flyweight objects.
  • concrete_flyweight_test.go: Unit tests for ConcreteFlyweight.
  • flyweight_factory_test.go: Unit tests for FlyweightFactory.
