// A mutable match of a phone number within a piece of text.
|
|
// Matches may be found using PhoneNumberUtil::FindNumbers.
|
|
//
|
|
// A match consists of the phone number as well as the start and end offsets of
|
|
// the corresponding subsequence of the searched text. Use raw_string() to
|
|
// obtain a copy of the matched subsequence.
|
|
//
|
|
// The following annotated example clarifies the relationship between the
|
|
// searched text, the match offsets, and the parsed number:
|
|
//
|
|
// string text = "Call me at +1 425 882-8080 for details.";
|
|
// const string country = "US";
|
|
//
|
|
// // Find the first phone number match:
|
|
// PhoneNumberMatcher matcher(text, country);
|
|
// if (matcher.HasNext()) {
|
|
// PhoneNumberMatch match;
|
|
// matcher.Next(&match);
|
|
// }
|
|
//
|
|
// // raw_string() contains the phone number as it appears in the text.
|
|
// "+1 425 882-8080" == match.raw_string();
|
|
//
|
|
// // start() and end() define the range of the matched subsequence.
|
|
// string subsequence = text.substr(match.start(), match.end());
|
|
// "+1 425 882-8080" == subsequence;
|
|
//
|
|
// // number() returns the the same result as PhoneNumberUtil::Parse()
|
|
// // invoked on raw_string().
|
|
// const PhoneNumberUtil& util = *PhoneNumberUtil::GetInstance();
|
|
// util.Parse(match.raw_string(), country).Equals(match.number());
|
|
