Abstract

Mondrian, an open-source visualization engine, uses a number of caches to avoid redundant computation. These caches are structured along Mondrian purpose: generating static twodimensional visualizations. We have noticed that the caches are meaningless for the evolution being made on Mondrian. Using aspect-oriented programming, we have refactored these caches into well defined aspects to address the evolution problem. We have achieved it without paying the price of runtime problems.
