Policy

Policy - Dart

The Policy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows you to change the algorithm used at runtime without modifying the client code. This is achieved by defining a common interface for all algorithms (the “policy”) and then having concrete policy …

Policy - Scala

The Policy pattern allows you to encapsulate a set of business rules or constraints into separate, reusable policy objects. This promotes separation of concerns and makes it easier to modify or extend the rules without affecting the core logic. The code defines a ValidationPolicy trait with a validate method. Concrete …

Policy - PHP

The Policy pattern encapsulates complex business logic or rules into separate classes, allowing for flexibility and maintainability. Instead of embedding these rules directly within an object, the object delegates the decision-making to a Policy object. This promotes the Single Responsibility Principle and makes it …

Policy - Ruby

The Policy pattern encapsulates business rules and logic related to permissions and authorization within dedicated policy objects. This promotes separation of concerns, making the code more maintainable and testable. Instead of scattering authorization checks throughout the application, a central policy determines if …

Policy - Swift

The Policy pattern allows you to encapsulate a complex set of business rules into separate, interchangeable policy objects. This promotes flexibility and maintainability by avoiding monolithic conditional logic. Instead of a single class making decisions based on numerous if/else statements, different policies can be …

Policy - Kotlin

The Policy pattern allows you to encapsulate a non-functional requirement (like security, logging, or caching) into a separate, reusable component. This avoids scattering such logic throughout your core business logic, promoting separation of concerns and making it easier to modify or extend these policies without …

Policy - Rust

The Policy pattern allows you to decouple the logic that determines if an operation is allowed from the operation itself. It achieves this by defining a “policy” – a trait or interface – that encapsulates the authorization rules. Different policies can be swapped in at runtime to change the behavior …

Policy - Go

The Policy pattern allows runtime modification of an object’s behavior without altering its core code. It achieves this by defining a set of policies (typically interfaces) that encapsulate different behaviors. An object (the context) can then accept and apply these policies dynamically. This promotes flexibility …

Policy - C

The Policy pattern allows you to define a family of algorithms (policies) and encapsulate each one into a separate class. It then allows the client to choose which algorithm to use at runtime without knowing the details of its implementation. This promotes loose coupling and flexibility.

Here, we define a data_t …

Policy - C++

The Policy pattern allows you to decouple algorithms from the specific ways they perform certain steps (policies). These policies are then injected into the algorithm, enabling runtime variation of behavior without modifying the algorithm itself. This promotes flexibility and reusability.

The C++ example demonstrates a …
