Josh: An Open AspectJ-like Language

Although aspect-oriented programming (AOP) is becoming widely used, the design of the pointcut language and the generic and reusable description of advice are still research topics. To address these topics, this paper presents Josh, which is our new AspectJ-like language with an extensible pointcut language and a few mechanisms for generic description. The extensible pointcut language is based on the idea of open compiler. Since Josh allows defining a new pointcut designator in Java, the users can define a pointcut designator useful in a particular application domain. Also, Josh allows any Java expression to be included in the body of advice. This mechanism enables the generic and reusable description of advice
