AOP: Aspect-Oriented Programming

AOP is an abbreviation of "Aspect-Oriented Programming". It is a programming paradigm that aspires towards raising modularity by enabling the partition or division of cross-cutting concerns in computing. It raises modularity by adding up supplemented activities to presented code (advice) devoid of altering the code itself; as an alternative individually indicating which code is customized through a "pointcut" design, such as "log all function calls when the function's name starts with a code 'set'".

This enables activities that are not essential to the business logic, as an example: logging, which is to be supplemented to a program devoid of disordering the code, central part to the usefulness and service. AOP structures a foundation for aspect-oriented software development.
AOP comprises techniques and tools of programming that hold up and maintain the modularization of concerns at the point of the source code, whereas "aspect-oriented software development" alludes to a complete engineering order and regulation.

History

• AOP has a number of direct predecessors A1 and A2:
  
  1. Reflection and Metaobject protocols.
  2. Subject-oriented programming.
  3. Composition Filters and Adaptive Programming.
• The precise idea of AOP was developed by Gregor Kiczales and colleagues at Xerox PARC, and they followed this with the AspectJ AOP extension to Java.
• In 2001, IBM's research team planned and projected Hyper/J and the Concern Manipulation Environment by following a tool approach over a language design approach, which has not seen broad practice or usage.
• The Microsoft Transaction Server is well thought-out to be the original chief application of AOP followed by Enterprise JavaBeans.

AOP Executions

The following mentioned below programming languages have executed AOP, within the language, or as a peripheral library, which comprises:

• .NET Framework languages (C# / VB.NET)
  
  • PostSharp is a commercial AOP execution with a free however limited edition.
  • Unity, it makes available an API to make easily verified practices in core areas of programming comprising data access, security, logging, exception handling, and others.
• ActionScript
• Ada
• AutoHotkey
• C / C++
• COBOL
• The Cocoa Objective-C frameworks
• ColdFusion
• Common Lisp
• Delphi
• Delphi Prism
• e (IEEE 1647)
• Emacs Lisp
• Groovy
• Haskell
• Java
• AspectJ
• JavaScript
• Logtalk
• Lua
• make
• Matlab
• ML
• Perl
• PHP
• Prolog
