Covers the strategy design pattern for defining a family of algorithms, encapsulating each one, and making them interchangeable. Enables selecting algorithms at runtime without modifying client code.

Strategy Pattern Guide

Implement the strategy pattern to encapsulate algorithms and make them interchangeable at runtime. Eliminates complex conditionals by delegating behavior to strategy objects.

Usage

Ask about implementing the strategy pattern, choosing between strategies at runtime, or refactoring conditional logic into strategies.

Examples

  • "Help me refactor this payment processing switch statement using strategy pattern"
  • "How do I implement different sorting strategies in Python?"
  • "When should I use strategy pattern vs template method?"

Guidelines

  • Each strategy should implement a common interface
  • Use strategy when you have multiple algorithms for the same task
  • Strategies work well with dependency injection frameworks
  • Consider using lambdas or functions for simple single-method strategies
  • The context class should not know the details of any strategy implementation
