| * \brief C API: Wrapper for 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> |
