Examples of AspectWerkzPreProcessor

org.codehaus.aspectwerkz.transform.AspectWerkzPreProcessor
AspectWerkzPreProcessor is the entry point of the AspectWerkz layer 2.
It implements the ClassPreProcessor interface defined in layer 1.
Available options are:
- -Daspectwerkz.transform.verbose=yes turns on verbose mode: print on stdout all non filtered class names and which transformation are applied
- -Daspectwerkz.transform.dump=org.myapp.* dumps transformed class matching pattern org.myapp.*(even unmodified ones) in ./_dump directory (relative to where applications starts). The syntax -Daspectwerkz.transform.dump=* matchs all classes. The pattern language is the same as pointcut pattern language.
- else -Daspectwerkz.transform.dump=org.myapp.*,before dumps class before and after the transformation whose name starts with org.myapp.(even unmodified ones) in ./_dump/before and ./_dump/after directories (relative to where application starts)
- -Daspectwerkz.transform.filter=no (or false) disables filtering of org.codehaus.aspectwerkz and related classes (trove, dom4j etc.). This should only be used in offline mode where weaving of those classes is needed. Setting this option in online mode will lead to ClassCircularityError.
