Abstract

A software system is defined by a tree of system models which are written in a functional language. During a build of the software system, the functions are interpreted and the results of the expensive expressions are cached. Each function is examined before interpretation to see if it has been evaluated before. If a function has already been evaluated, the cached result is retrieved by the evaluator and the time which would have been spent re-evaluating the function is saved.
