The Exception Handling Pattern in the Architectural Layers Using Aspect-Oriented Programming

摘要

Aspect-Oriented Programming(AOP) is intended to ease situations that involve many kinds of code tangling. This paper reports on a practice to import AOP's ability to ease tangling related to exception handling pattern. We took an existing framework, the exception handing application block(EHAB) and unity application block(UAB). EHAB provides exception handlers and policies to enable us to make configurable and consistent code in architectural layers. UAB provides interception mechanism to make clean code using AOP.
