AspectJ™ is a simple and practical aspect-oriented extension to Java™. With just a few new constructs, AspectJ provides support for modular implementation of a range of crosscutting concerns. In AspectJ's dynamic join point model, join points are well-defined points in the execution of the program; pointcuts are collections of join points; advice are(More)
59 M Many software developers are attracted to the idea of AOP—they recognize the concept of crosscutting concerns and know they have had problems with the implementation of such concerns in the past. But they have questions about how to adopt AOP into their development process, including: How to use aspects in existing code? What kinds of benefits can be(More)
This paper describes the implementation of advice weaving in AspectJ. The AspectJ language picks out dynamic join points in a program's execution with pointcuts and uses advice to change the behavior at those join points. The core task of AspectJ's advice weaver is to statically transform a program so that at runtime it will behave according to the AspeetJ(More)

Introduction Crosscutting poses some challenges in terms of clean separation of concerns. Aspect-oriented programming [2] is intended to address those challenges. This position paper presents a couple of examples of situations that involve crosscutting. The first example illustrates some basic crosscutting that all technologies for advanced separation of(More)
Most of the existing literature about monadic programming focuses on theory but does not address issues of software engineering. Using monadic parsing as a running example, we demonstrate monadic programs written in a typical style, recognize how they violate abstraction boundaries, and recover clean abstraction crossings through monadic reflection. Once(More)
Much of the monadic programming literature gets the types right but the abstraction wrong. Using monadic parsing as the motivating example, we demonstrate standard monadic programs in Scheme, recognize how they violate abstraction boundaries, and recover clean abstraction crossings through monadic reeection. Once monadic reeection is made explicit , it is(More)
Complex systems usually contain design units that are logically related to several objects in the system. Some examples include: tracing, propagation of interrupts, multi-object protocols, security enforcement etc. This crosscutting between those design units and the objects is a natural phenomenon. But, using traditional implementation techniques, the(More)
