Strategy

Strategy - Dart

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows an algorithm to vary independently from the clients that use it. This example demonstrates the Strategy pattern by defining different shipping cost calculation strategies (Standard, Express, Overnight). …

Strategy - Scala

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows an algorithm to vary independently from the clients that use it. This example demonstrates using traits in Scala to define different shipping cost calculation strategies. The ShippingCostCalculator …

Strategy - PHP

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows an algorithm to vary independently from the clients that use it. This implementation uses an interface PaymentStrategy to define a common method for making payments. Concrete strategies like …

Strategy - Ruby

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows an algorithm to vary independently from the clients that use it. Here, we define different shipping cost calculation strategies (e.g., for ground, air). The ShippingContext class accepts a strategy …

Strategy - Swift

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows an algorithm to vary independently from the clients that use it. In this Swift implementation, we define a protocol SortingStrategy with a single method sort. Different concrete strategies like …

Strategy - Kotlin

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows an algorithm to vary independently from clients that use it. In this Kotlin example, we use a functional approach with function types to define different shipping strategies (e.g., ground, air). The …

Strategy - Rust

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows an algorithm to vary independently from the clients that use it. Here, we define a trait CompressionStrategy representing the compression algorithms. Concrete strategies like ZipCompression and …

Strategy - Go

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It lets you vary an algorithm independently from clients that use it. This implementation uses interfaces to define the strategy (a ShippingMethod interface with a CalculateCost method). Concrete strategies …

Strategy - C

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows selecting an algorithm at runtime without modifying the client code. This implementation achieves this by defining a function pointer type Operation representing the strategy. Different operation …

Strategy - C++

The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows an algorithm to vary independently from the clients that use it. This is achieved by having a context class that holds a strategy object and delegates work to it.

The C++ code implements this using an …
