/**
 * The immutable match of a phone number within a piece of text. Matches may be found using
 * {@link PhoneNumberUtil#findNumbers}.
 *
 * <p>A match consists of the {@linkplain #number() phone number} as well as the
 * {@linkplain #start() start} and {@linkplain #end() end} offsets of the corresponding subsequence
 * of the searched text. Use {@link #rawString()} to obtain a copy of the matched subsequence.
 *
 * <p>The following annotated example clarifies the relationship between the searched text, the
 * match offsets, and the parsed number:

 * <pre>
 * CharSequence text = "Call me at +1 425 882-8080 for details.";
 * String country = "US";
 * PhoneNumberUtil util = PhoneNumberUtil.getInstance();
 *
 * // Find the first phone number match:
 * PhoneNumberMatch m = util.findNumbers(text, country).iterator().next();
 *
 * // rawString() contains the phone number as it appears in the text.
 * "+1 425 882-8080".equals(m.rawString());
 *
 * // start() and end() define the range of the matched subsequence.
 * CharSequence subsequence = text.subSequence(m.start(), m.end());
 * "+1 425 882-8080".contentEquals(subsequence);
 *
 * // number() returns the the same result as PhoneNumberUtil.{@link PhoneNumberUtil#parse parse()}
 * // invoked on rawString().
 * util.parse(m.rawString(), country).equals(m.number());
 * </pre>
