In computing, aspect-oriented programming (AOP) is a programming paradigm that aims to increase modularity by allowing the separation of cross-cutting concerns.It does so by adding behavior to existing code (an advice) without modifying the code, instead separately specifying which code is modified via a "pointcut" specification, such as "log all function calls when the function's name begins ...
One view of aspect-oriented software development is that every major feature of the program, core concern (business logic), or cross-cutting concern (additional features), is an aspect, and by weaving them together (a process also called composition), one finally produces a whole out of the separate aspects. This approach is known as pure ...
Aspect-oriented programming enables developers to add new functionality to code, known as "advice", without modifying that code itself; rather, it uses a pointcut to implement the advice into code blocks. Ada; AspectJ; Groovy; Nemerle; Raku [2] [3]
This ensures that any existing object oriented code will still be valid aspect-oriented code and that development will feel like a natural extension of the object-oriented language. [5] The AspectC++ programming language extends C++ through the use of an aspect weaver, offering the additional efficiency over AspectJ that is needed for embedded ...

In aspect-oriented programming, a pointcut is a set of join points. Pointcut specifies where exactly to apply advice, which allows separation of concerns and helps in modularizing business logic. [1] Pointcuts are often specified using class names or method names, in some cases using regular expressions that match class or method name.

Aspect-oriented programming languages can separate concerns into aspects and objects. Separation of concerns is an important design principle in many other areas as well, such as urban planning , architecture and information design . [ 5 ]
