AspectC++ is an aspect-oriented language extension for C++. Its
design was strongly influenced by the core concepts of AspectJ
and, thus, can be seen as an AspectJ equivalent in the C++
world. With this demonstration the AspectC++ developer team
wants to increase the awareness of the project and its current
state in the AOSD community. Furthermore, it should be
demonstrated that AOP with C++ can be much easier to understand
and much more powerful than approaches, which are based on C++
template meta-programming. There are several domains in computer
science and the IT industry where C/C++ still dominates Java.
One of these domains is the area of small (so called “deeply”)
embedded systems. This area is characterized by extreme resource
constraints in the sense of memory and processing power. Most of
these embedded systems are equipped with 8 bit microcontrollers
and only a few Kbytes of RAM. However, in year 2000 the segment
of 4 and 8 bit microcontrollers had a market share of 80% of all
produced units. With AspectC++ it is now possible to apply AOSD
concepts even in such restricted, but very important, domains.
The focus of the demonstration will therefore be the minimal
resource consumption of the AspectC++ generated code and its
runtime system. This will be underlined by the presentation of a
small embedded device equipped with meteorological sensors and
an 8 bit microcontroller running AspectC++ code. The whole
picture of the language and its implementation will be rounded
up with a demonstration of the unique language features of
AspectC++. One of these features is the Aspect Behavior Contract
(ABC) concept, which helps to reduce the number of required
tests after changes in aspect or component code. Depending on
the state of the implementation in march it is also planned to
extend the code of a well-known open source project with an
aspect during the demonstration. This should point out the
standard and dialect conformance of the AspectC++ parser and
proves that the implementation has reached a state where it can
deal with real-world projects.
