Abstract:
It is generally accepted that object-oriented programming and
distributed computing fit together well, because distribution can
be easily integrated into object-oriented systems in a transparent
manner. But while transparency is desirable with respect to code
readability and reusability, it can cause severe performance
problems, because the programmer loses control over distribution.
This paper presents an approach to solving this conflict with
Aspect-Oriented Programming: The basic functionality of the program
can be formulated in a completely distribution-transparent manner,
whereas the programmer retains complete control over the
distribution through the aspect language D2AL. D2AL differs from
other aspect languages in that it is based on the design of the
application, not on its implementation. We show that using the
design as the basis of D2AL gives access to abstractions that
greatly increase the expressiveness, as compared to an
implementation-based aspect language.
