- * [Match] contains methods to manipulate a regular expression match.
- *
- * Iterables of [Match] objects are returned from [RegExp] matching methods.
- *
- * The following example finds all matches of a [RegExp] in a [String]
- * and iterates through the returned iterable of [Match] objects.
- *
- *     RegExp exp = const RegExp(@"(\w+)");
- *     String str = "Parse my string";
- *     Iterable<Match> matches = exp.allMatches(str);
- *     for (Match m in matches) {
- *       String match = m.group(0);
- *       print(match);
- *     };
- *
- * The output of the example is:
- *
- *     Parse
- *     my
- *     string
