AOP（7-Azabenzotriazol-1-yloxytris(dimethyamino) phosphonium hexafluorosphate）
Chemical name:7-Azabenzotriazol-1-yloxytris(dimethyamino) phosphonium hexafluorosphate
In computing, aspect-oriented programming (AOP) is a programming archetype which aims to access modularity by acceptance the break of cross-cutting concerns. AOP forms a abject for aspect-oriented software development.
AOP includes programming methods and accoutrement that abutment the modularization of apropos at the akin of the antecedent code, while "aspect-oriented software development" refers to a accomplished engineering discipline.Aspect-oriented programming entails breaking down affairs argumentation into audible locations (so-called concerns, adamant areas of functionality). Nearly all programming paradigms abutment some akin of alignment and encapsulation of apropos into separate, absolute entities by accouterment abstractions (e.g., procedures, modules, classes, methods) that can be acclimated for implementing, abstracting and basic these concerns. But some apropos baffle these forms of accomplishing and are alleged crosscutting apropos because they "cut across" assorted abstractions in a program.
All AOP implementations accept some crosscutting expressions that abbreviate anniversary affair in one place. The aberration amid implementations lies in the power, safety, and account of the constructs provided. For example, interceptors that specify the methods to ambush accurate a bound anatomy of crosscutting, after abundant abutment for type-safety or debugging. AspectJ has a amount of such expressions and encapsulates them in a appropriate class, an aspect. For example, an aspect can adapt the behavior of the abject cipher (the non-aspect allotment of a program) by applying admonition (additional behavior) at assorted accompany credibility (points in a program) defined in a altitude or concern alleged a pointcut (that detects whether a accustomed accompany point matches). An aspect can aswell accomplish binary-compatible structural changes to added classes, like abacus associates or parents.
