-/**
- * DateIntervalInfo is a public class for encapsulating localizable
- * date time interval patterns. It is used by DateIntervalFormat.
- *
- * <P>
- * For most users, ordinary use of DateIntervalFormat does not need to create
- * DateIntervalInfo object directly.
- * DateIntervalFormat will take care of it when creating a date interval
- * formatter when user pass in skeleton and locale.
- *
- * <P>
- * For power users, who want to create their own date interval patterns,
- * or want to re-set date interval patterns, they could do so by
- * directly creating DateIntervalInfo and manupulating it.
- *
- * <P>
- * Logically, the interval patterns are mappings
- * from (skeleton, the_largest_different_calendar_field)
- * to (date_interval_pattern).
- *
- * <P>
- * A skeleton
- * <ol>
- * <li>
- * only keeps the field pattern letter and ignores all other parts
- * in a pattern, such as space, punctuations, and string literals.
- * <li>
- * hides the order of fields.
- * <li>
- * might hide a field's pattern letter length.
- *
- * For those non-digit calendar fields, the pattern letter length is
- * important, such as MMM, MMMM, and MMMMM; EEE and EEEE,
- * and the field's pattern letter length is honored.
- *
- * For the digit calendar fields, such as M or MM, d or dd, yy or yyyy,
- * the field pattern length is ignored and the best match, which is defined
- * in date time patterns, will be returned without honor the field pattern
- * letter length in skeleton.
- * </ol>
- *
- * <P>
- * The calendar fields we support for interval formatting are:
- * year, month, date, day-of-week, am-pm, hour, hour-of-day, and minute.
- * Those calendar fields can be defined in the following order:
- * year > month > date > am-pm > hour > minute
- *
- * The largest different calendar fields between 2 calendars is the
- * first different calendar field in above order.
- *
- * For example: the largest different calendar fields between &quot;Jan 10, 2007&quot;
- * and &quot;Feb 20, 2008&quot; is year.
- *
- * <P>
- * There is a set of pre-defined static skeleton strings.
- * There are pre-defined interval patterns for those pre-defined skeletons
- * in locales' resource files.
- * For example, for a skeleton UDAT_YEAR_ABBR_MONTH_DAY, which is &quot;yMMMd&quot;,
- * in en_US, if the largest different calendar field between date1 and date2
- * is &quot;year&quot;, the date interval pattern is &quot;MMM d, yyyy - MMM d, yyyy&quot;,
- * such as &quot;Jan 10, 2007 - Jan 10, 2008&quot;.
- * If the largest different calendar field between date1 and date2 is &quot;month&quot;,
- * the date interval pattern is &quot;MMM d - MMM d, yyyy&quot;,
- * such as &quot;Jan 10 - Feb 10, 2007&quot;.
- * If the largest different calendar field between date1 and date2 is &quot;day&quot;,
- * the date interval pattern is &quot;MMM d-d, yyyy&quot;, such as &quot;Jan 10-20, 2007&quot;.
- *
- * For date skeleton, the interval patterns when year, or month, or date is
- * different are defined in resource files.
- * For time skeleton, the interval patterns when am/pm, or hour, or minute is
- * different are defined in resource files.
- *
- *
- * <P>
- * There are 2 dates in interval pattern. For most locales, the first date
- * in an interval pattern is the earlier date. There might be a locale in which
- * the first date in an interval pattern is the later date.
- * We use fallback format for the default order for the locale.
- * For example, if the fallback format is &quot;{0} - {1}&quot;, it means
- * the first date in the interval pattern for this locale is earlier date.
- * If the fallback format is &quot;{1} - {0}&quot;, it means the first date is the
- * later date.
- * For a particular interval pattern, the default order can be overriden
- * by prefixing &quot;latestFirst:&quot; or &quot;earliestFirst:&quot; to the interval pattern.
- * For example, if the fallback format is &quot;{0}-{1}&quot;,
- * but for skeleton &quot;yMMMd&quot;, the interval pattern when day is different is
- * &quot;latestFirst:d-d MMM yy&quot;, it means by default, the first date in interval
- * pattern is the earlier date. But for skeleton &quot;yMMMd&quot;, when day is different,
- * the first date in &quot;d-d MMM yy&quot; is the later date.
- *
- * <P>
- * The recommended way to create a DateIntervalFormat object is to pass in
- * the locale.
- * By using a Locale parameter, the DateIntervalFormat object is
- * initialized with the pre-defined interval patterns for a given or
- * default locale.
- * <P>
- * Users can also create DateIntervalFormat object
- * by supplying their own interval patterns.
- * It provides flexibility for power users.
- *
- * <P>
- * After a DateIntervalInfo object is created, clients may modify
- * the interval patterns using setIntervalPattern function as so desired.
- * Currently, users can only set interval patterns when the following
- * calendar fields are different: ERA, YEAR, MONTH, DATE, DAY_OF_MONTH,
- * DAY_OF_WEEK, AM_PM, HOUR, HOUR_OF_DAY, and MINUTE.
- * Interval patterns when other calendar fields are different is not supported.
- * <P>
- * DateIntervalInfo objects are cloneable.
- * When clients obtain a DateIntervalInfo object,
- * they can feel free to modify it as necessary.
- * <P>
- * DateIntervalInfo are not expected to be subclassed.
- * Data for a calendar is loaded out of resource bundles.
- * Through ICU 4.4, date interval patterns are only supported in the Gregorian
- * calendar; non-Gregorian calendars are supported from ICU 4.4.1.
