Subject cvs commit: jakarta-commons/validator/conf/share ValidatorCheckStyle.xml

  Added:       validator/conf/share ValidatorCheckStyle.xml
  Add a checkstyle.xml, this still needs to
  be voted on and trimmed down because it is very noisy.
  PMD is a better tool for most of these items.
  Revision  Changes    Path
  1.1                  jakarta-commons/validator/conf/share/ValidatorCheckStyle.xml
  Index: ValidatorCheckStyle.xml
  <?xml version="1.0"?>
      "-//Puppy Crawl//DTD Check Configuration 1.1//EN"
    These checks still need to be Voted on for Validator, but
    at least serve to cut down on some of the noise. 
    A Checkstyle configuration that checks against the recommendations
    in Joshua Bloch, Effective Java (highliy recommended read!)
    This file does NOT duplicate the checks for whitespace settings,
    placement of curly braces, etc.  Only the rules that are explicitly
    mentioned in the book are enforced.
    Currently the amount of rules that can be automatically checked by
    Checkstyle is not very large, but adding more checks of this quality
    is a high priority goal for the development team.

           interesting to know whether Joshua meant what checkstyle implements.
           We feel this implementation is well suited as a warning,
           i.e. if you get error messages from this check you should be
           able to name a good reason to implement your code the way you do it,
           especially if you are designing a library and not an application. -->
