    - #### matched

          public abstract void matched(URI uri)
                                throws Exception

      Throws:
        `Exception`

    - #### match

          public void match(Pattern pattern,
                   URI[] uris,
                   boolean isNullInclusive)
                     throws Exception

      Find jar names from the provided list matching a pattern. If the pattern is null and isNullInclusive is true, then all jar names will match. A pattern is a set of acceptable jar names. Each acceptable jar name is a regex. Each regex can be separated by either a "," or a "|". If you use a "|" this or's together the jar name patterns. This means that ordering of the matches is unimportant to you. If instead, you want to match particular jar names, and you want to match them in order, you should separate the regexs with "," instead. Eg "aaa-.\*\.jar|bbb-.\*\.jar" Will iterate over the jar names and match in any order. Eg "aaa-\*\.jar,bbb-.\*\.jar" Will iterate over the jar names, matching all those starting with "aaa-" first, then "bbb-".
      Parameters:
        `pattern` - the pattern
        `uris` - the uris to test the pattern against
        `isNullInclusive` - if true, an empty pattern means all names match, if false, none match
      Throws:
        `Exception`

    - #### matchPatterns

          public void matchPatterns(Pattern pattern,
                           URI[] uris,
                           boolean isNullInclusive)
                             throws Exception

      Throws:
        `Exception`
