A result from searching within a string.

A Match or an Iterable of Match objects is returned from Pattern 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 = new RegExp(r"(\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

Some patterns, regular expressions in particular, may record substrings that were part of the matching. These are called groups in the Match object. Some patterns may never have any groups, and their matches always have zero groupCount.
