A "join point" is a clearly definedpoint in a program source code (process description) where the concern crosscuts the program (delivery process) (and where an extension may occur).
A join point is "a well-definedpoint in the program flow." 3 There are many types of join points, such as a method call or a method return, which can be either a normal return or a thrown exception.
