/**
|
||||
* 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 "Jan 10, 2007"
|
||||
* and "Feb 20, 2008" 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 "yMMMd",
|
||||
* in en_US, if the largest different calendar field between date1 and date2
|
||||
* is "year", the date interval pattern is "MMM d, yyyy - MMM d, yyyy",
|
||||
* such as "Jan 10, 2007 - Jan 10, 2008".
|
||||
* If the largest different calendar field between date1 and date2 is "month",
|
||||
* the date interval pattern is "MMM d - MMM d, yyyy",
|
||||
* such as "Jan 10 - Feb 10, 2007".
|
||||
* If the largest different calendar field between date1 and date2 is "day",
|
||||
* the date interval pattern is "MMM d-d, yyyy", such as "Jan 10-20, 2007".
|
||||
*
|
||||
* 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 "{0} - {1}", it means
|
||||
* the first date in the interval pattern for this locale is earlier date.
|
||||
* If the fallback format is "{1} - {0}", it means the first date is the
|
||||
* later date.
|
||||
* For a particular interval pattern, the default order can be overriden
|
||||
* by prefixing "latestFirst:" or "earliestFirst:" to the interval pattern.
|
||||
* For example, if the fallback format is "{0}-{1}",
|
||||
* but for skeleton "yMMMd", the interval pattern when day is different is
|
||||
* "latestFirst:d-d MMM yy", it means by default, the first date in interval
|
||||
* pattern is the earlier date. But for skeleton "yMMMd", when day is different,
|
||||
* the first date in "d-d MMM yy" 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.
