/**

* \file
|
|
* \brief C API: Wrapper for icu::DateTimePatternGenerator (unicode/dtptngen.h).
|
|
*
|
|
* UDateTimePatternGenerator provides flexible generation of date format patterns,
|
|
* like "yy-MM-dd". The user can build up the generator by adding successive
|
|
* patterns. Once that is done, a query can be made using a "skeleton", which is
|
|
* a pattern which just includes the desired fields and lengths. The generator
|
|
* will return the "best fit" pattern corresponding to that skeleton.
|
|
* <p>The main method people will use is udatpg_getBestPattern, since normally
|
|
* UDateTimePatternGenerator is pre-built with data from a particular locale.
|
|
* However, generators can be built directly from other data as well.
|
|
* <p><i>Issue: may be useful to also have a function that returns the list of
|
|
* fields in a pattern, in order, since we have that internally.
|
|
* That would be useful for getting the UI order of field elements.</i>

* The DateTimeFormat is a message format pattern used to compose date and

* time patterns. The default pattern in the root locale is "{1} {0}", where
|
|
* {1} will be replaced by the date pattern and {0} will be replaced by the
|
|
* time pattern; however, other locales may specify patterns such as
|
|
* "{1}, {0}" or "{1} 'at' {0}", etc.
|
|
* <p>
|
|
* This is used when the input skeleton contains both date and time fields,
|
|
* but there is not a close match among the added patterns. For example,
|
|
* suppose that this object was created by adding "dd-MMM" and "hh:mm", and
|
|
* its DateTimeFormat is the default "{1} {0}". Then if the input skeleton
|
|
* is "MMMdhmm", there is not an exact match, so the input skeleton is
|
|
* broken up into two components "MMMd" and "hmm". There are close matches
|
|
* for those two skeletons, so the result is put together with this pattern,

|
* resulting in "d-MMM h:mm".
