| This technique of adding behavior to annotations is interesting, although it begs the question why the language won't let you do it "natively". <br/>I recently implemented an alternative approach to support "Design by Contract". I use Sun's Annotation Processor Tool (APT) to parse source, looking for special annotations that define contract tests, and then I generate AspectJ code that inserts the tests in the runtime jar. See Contract4J.org for more information. | ||
