 /**
  * <code>FieldPosition</code> is a simple class used by <code>Format</code>
  * and its subclasses to identify fields in formatted output. Fields are
  * identified by constants, whose names typically end with <code>_FIELD</code>,
  * defined in the various subclasses of <code>Format</code>. See
  * <code>ERA_FIELD</code> and its friends in <code>DateFormat</code> for
  * an example.
  *
  * <p>
  * <code>FieldPosition</code> keeps track of the position of the
  * field within the formatted output with two indices: the index
  * of the first character of the field and the index of the last
  * character of the field.
  *
  * <p>
  * One version of the <code>format</code> method in the various
  * <code>Format</code> classes requires a <code>FieldPosition</code>
  * object as an argument. You use this <code>format</code> method
  * to perform partial formatting or to get information about the
  * formatted output (such as the position of a field).
  *
  * The FieldPosition class is not suitable for subclassing.
  *
  * <p>
  * Below is an example of using <code>FieldPosition</code> to aid
  * alignment of an array of formatted floating-point numbers on
  * their decimal points:
  * <pre>
  * \code
  *       double doubleNum[] = {123456789.0, -12345678.9, 1234567.89, -123456.789,
  *                  12345.6789, -1234.56789, 123.456789, -12.3456789, 1.23456789};
  *       int dNumSize = (int)(sizeof(doubleNum)/sizeof(double));
  *
  *       UErrorCode status = U_ZERO_ERROR;
  *       DecimalFormat* fmt = (DecimalFormat*) NumberFormat::createInstance(status);
  *       fmt->setDecimalSeparatorAlwaysShown(true);
  *
  *       const int tempLen = 20;
  *       char temp[tempLen];
  *
  *       for (int i=0; i<dNumSize; i++) {
  *           FieldPosition pos(NumberFormat::INTEGER_FIELD);
  *           UnicodeString buf;
  *           char fmtText[tempLen];
  *           ToCharString(fmt->format(doubleNum[i], buf, pos), fmtText);
  *           for (int j=0; j<tempLen; j++) temp[j] = ' '; // clear with spaces
  *           temp[__min(tempLen, tempLen-pos.getEndIndex())] = '\0';
  *           cout << temp << fmtText   << endl;
  *       }
  *       delete fmt;
  * \endcode
  * </pre>
  * <p>
  * The code will generate the following output:
  * <pre>
  * \code
  *           123,456,789.000
  *           -12,345,678.900
  *             1,234,567.880
  *              -123,456.789
  *                12,345.678
  *                -1,234.567
  *                   123.456
  *                   -12.345
  *                     1.234
  *  \endcode
  * </pre>
