Design Patterns In Kotlin
This project is a reference collection of practical examples demonstrating the implementation of common software design patterns in Kotlin. It serves as a guide to architectural best practices and object-oriented principles through the application of behavioral, creational, and structural patterns.
The collection provides concrete implementations to demonstrate how to decouple object instantiation, manage communication and responsibility between objects, and organize complex class and object relationships.
The reference covers creational patterns such as factories and builders, structural patterns including adapters and composites, and behavioral patterns such as observers and strategies.
Features
- Kotlin Architectural Patterns - Serves as a comprehensive reference for applying proven design patterns to create modular Kotlin application structures.
- Concrete Factory Implementations - Provides practical examples of using factory methods to return objects of a common interface.
- Behavioral Object Logic - Implements patterns that manage how objects communicate and change behavior to control application state.
- Behavioral Design Patterns - Provides concrete implementations of behavioral patterns such as Observer and Strategy.
- Mediator Patterns - Implements the mediator pattern to coordinate communication between multiple objects through a central point.
- Memento Patterns - Implements the memento pattern for capturing and storing an object's internal state for future restoration.
- Strategy Patterns - Implements the strategy pattern to define a family of interchangeable algorithms selectable at runtime.
- Visitor Patterns - Implements the visitor pattern to separate algorithms from the complex data structures they operate on.
- Chain of Responsibility Implementations - Implements the chain of responsibility pattern to delegate request processing across a series of handler objects.
- Chain of Responsibility Patterns - Implements the behavioral design pattern that passes requests along a chain of handlers until one processes the action.
- Command Patterns - Provides an implementation of the command pattern to encapsulate requests as discrete objects for queuing.
- Interface-Based Decoupling - Demonstrates the use of abstract interfaces to decouple high-level logic from concrete implementations.
- Creational Design Patterns - Provides implementations of factories, builders, and singletons to decouple object instantiation.
- Builder Patterns - Implements the builder pattern to construct complex objects through a managed sequence of steps.
- Factory Method Patterns - Implements the factory method pattern to determine the object type to instantiate at runtime.
- Singleton Patterns - Implements the singleton pattern to ensure a class has only one instance with global access.
- Decorator Pattern Implementations - Implements the decorator pattern to extend object functionality by wrapping them in a class that shares the same interface.
- Design Pattern Collections - Provides a curated collection of common software design patterns implemented in Kotlin.
- Creational Patterns - Implements creational patterns like Factory and Builder to manage object instantiation.
- Notification Observation Patterns - Provides implementations of observer patterns to manage event notifications and subscriber updates.
- Object Builders - Implements the builder pattern to separate the construction of complex objects from their representation.
- Object Composition Patterns - Implements design strategies that prioritize object composition over inheritance to reduce coupling in Kotlin.
- Abstract Factories - Implements the abstract factory pattern to create families of related objects without specifying concrete classes.
- Observer Patterns - Implements the observer pattern to enable subjects to notify multiple subscribers of state changes.
- State-Driven Logic - Demonstrates state-driven logic where object behavior changes based on discrete operational states at runtime.
- State Patterns - Implements the state pattern to encapsulate state-specific logic into separate classes that alter object behavior at runtime.
- Structural Design Patterns - Organizes classes and objects using structural patterns like adapters, composites, and facades.
- Proxy Patterns - Implements the Proxy pattern to provide a surrogate for controlling object access.
- Adapter Patterns - Implements the Adapter pattern to enable communication between incompatible interfaces.
- Compositional Design Patterns - Demonstrates improving code flexibility by replacing rigid inheritance with flexible compositional patterns.
- Decorator Patterns - Implements the Decorator pattern to dynamically extend object functionality without inheritance.
- Facades - Implements the Facade pattern to provide a simplified interface to complex internal components.
- Composite Patterns - Implements the Composite pattern to treat individual objects and compositions uniformly.
- Programming Language Patterns - Design patterns implemented using Kotlin language features.
