Aspect-Oriented Programming

Aspect-oriented programming (AOP)

Aspect-oriented programming (AOP) is a programming paradigm that provides a modular way to structure software by separating cross-cutting concerns from the main business logic. Cross-cutting concerns are aspects of a program that affect multiple modules and are often scattered throughout the codebase. Examples of cross-cutting concerns include logging, error handling, security, and performance monitoring.

In traditional object-oriented programming (OOP), concerns like logging or error handling are often interwoven with the core functionality of the application. AOP aims to address this by allowing developers to express these concerns separately and then weave them into the application at appropriate points. This is accomplished without altering the core business logic.

Key concepts in AOP

Key concepts in AOP are as follows:

Aspect

An aspect is a module that encapsulates cross-cutting concerns. It defines a set of related behaviors or responsibilities that cut across multiple parts of the code. Aspects are separate from the main business logic and are used to modularize concerns such as logging, ...
