Policy

Policy - C#

The Policy pattern allows you to encapsulate a changeable algorithm or set of rules into a separate object. This promotes flexibility as you can swap out different policies at runtime without modifying the core logic that uses the policy. This example demonstrates a simple pricing policy. The PricingService class …

Policy - TypeScript

The Policy pattern defines a family of algorithms and encapsulates each one into a separate class. It then allows the client to select the appropriate algorithm at runtime. This promotes loose coupling and allows for easy extension of functionality without modifying existing code.

This TypeScript implementation uses an …

Policy - JavaScript

The Policy pattern allows you to dynamically apply different behaviors or rules to an object based on certain conditions, without modifying the object itself. It decouples the decision-making logic (the policy) from the object being governed. This is achieved by defining a policy object that contains methods …

Policy - Python

The Policy pattern allows for runtime modification of object behavior without altering the object’s code. It achieves this by encapsulating the behavior within separate policy classes, and allowing the object to accept different policies as needed. This promotes flexibility and adheres to the Open/Closed …

Policy - Java

The Policy pattern allows for runtime selection of algorithms or behaviors based on configurable rules. It decouples the decision-making process (the policy) from the specific implementations (the strategies). This promotes flexibility and avoids hardcoding logic.

The Java implementation uses an interface …
