Abstract:

Pointcuts position definition is not clear and weaving operation is inconvenient are two problems in existing aspectoriented network software evolution method. To address the two issues, an aspectoriented network software evolution method supported by RoleGoalProcessServices (RGPS) process metamodel is proposed. In this method, process is defined by RGPS process metamodel and pointcuts position is defined by metamodel control structure. Aspect pointcuts position definition is precise and can be woven in the original process seamlessly because of the consistent definition of aspect and process. Process evolution is defined using formal method and aspect weaving ways in evolution are clearly elaborated. Finally, a case is used to illustrate the aspect weaving process in the evolution method.
