The realization of Aspectual State Model with UML extension mechanism

Current abstractions offered by the object-oriented paradigm are insufficient to fully express all the concerns of a software system. For example, non-functional concerns namely cross-cutting concerns such as logging, tracing, or data persistence tend to be scattered and tangled all across the classes of the system. Aspect-oriented programming (AOP), which allows for modularizing concerns has effectively solved the problem that the object-oriented programming (OOP) has encountered. At present, the AOP paradigm has expanded to all the lifecycle of the software development, as a result, aspect-oriented software development (AOSD) is becoming a new technique, which has an important step of modeling the aspects. We present, in this paper, a statecharts describes the aspectual state model (ASM) based on the unified modeling language (UML) and its extension mechanism to identify the cross-cutting concerns, using a mature language AspectJ which is a seamless aspect-oriented extension to the Java programming language to write aspect codes.
