| * Resolves parsed {@code ChronoField} values into a date during parsing. |
| * <p> |
| * Most {@code TemporalField} implementations are resolved using the |
| * resolve method on the field. By contrast, the {@code ChronoField} class |
| * defines fields that only have meaning relative to the chronology. |
| * As such, {@code ChronoField} date fields are resolved here in the |
| * context of a specific chronology. |
| * <p> |
| * {@code ChronoField} instances are resolved by this method, which may |
| * be overridden in subclasses. |
| * <ul> |
| * <li>{@code EPOCH_DAY} - If present, this is converted to a date and |
| * all other date fields are then cross-checked against the date. |
| * <li>{@code PROLEPTIC_MONTH} - If present, then it is split into the |
| * {@code YEAR} and {@code MONTH_OF_YEAR}. If the mode is strict or smart |
| * then the field is validated. |
| * <li>{@code YEAR_OF_ERA} and {@code ERA} - If both are present, then they |
| * are combined to form a {@code YEAR}. In lenient mode, the {@code YEAR_OF_ERA} |
| * range is not validated, in smart and strict mode it is. The {@code ERA} is |
| * validated for range in all three modes. If only the {@code YEAR_OF_ERA} is |
| * present, and the mode is smart or lenient, then the last available era |
| * is assumed. In strict mode, no era is assumed and the {@code YEAR_OF_ERA} is |
| * left untouched. If only the {@code ERA} is present, then it is left untouched. |
| * <li>{@code YEAR}, {@code MONTH_OF_YEAR} and {@code DAY_OF_MONTH} - |
| * If all three are present, then they are combined to form a date. |
| * In all three modes, the {@code YEAR} is validated. |
| * If the mode is smart or strict, then the month and day are validated. |
| * If the mode is lenient, then the date is combined in a manner equivalent to |
| * creating a date on the first day of the first month in the requested year, |
| * then adding the difference in months, then the difference in days. |
| * If the mode is smart, and the day-of-month is greater than the maximum for |
| * the year-month, then the day-of-month is adjusted to the last day-of-month. |
| * If the mode is strict, then the three fields must form a valid date. |
| * <li>{@code YEAR} and {@code DAY_OF_YEAR} - |
| * If both are present, then they are combined to form a date. |
| * In all three modes, the {@code YEAR} is validated. |
| * If the mode is lenient, then the date is combined in a manner equivalent to |
| * creating a date on the first day of the requested year, then adding |
| * the difference in days. |
| * If the mode is smart or strict, then the two fields must form a valid date. |
| * <li>{@code YEAR}, {@code MONTH_OF_YEAR}, {@code ALIGNED_WEEK_OF_MONTH} and |
| * {@code ALIGNED_DAY_OF_WEEK_IN_MONTH} - |
| * If all four are present, then they are combined to form a date. |
| * In all three modes, the {@code YEAR} is validated. |
| * If the mode is lenient, then the date is combined in a manner equivalent to |
| * creating a date on the first day of the first month in the requested year, then adding |
| * the difference in months, then the difference in weeks, then in days. |
| * If the mode is smart or strict, then the all four fields are validated to |
| * their outer ranges. The date is then combined in a manner equivalent to |
| * creating a date on the first day of the requested year and month, then adding |
| * the amount in weeks and days to reach their values. If the mode is strict, |
| * the date is additionally validated to check that the day and week adjustment |
| * did not change the month. |
| * <li>{@code YEAR}, {@code MONTH_OF_YEAR}, {@code ALIGNED_WEEK_OF_MONTH} and |
| * {@code DAY_OF_WEEK} - If all four are present, then they are combined to |
| * form a date. The approach is the same as described above for |
| * years, months and weeks in {@code ALIGNED_DAY_OF_WEEK_IN_MONTH}. |
| * The day-of-week is adjusted as the next or same matching day-of-week once |
| * the years, months and weeks have been handled. |
| * <li>{@code YEAR}, {@code ALIGNED_WEEK_OF_YEAR} and {@code ALIGNED_DAY_OF_WEEK_IN_YEAR} - |
| * If all three are present, then they are combined to form a date. |
| * In all three modes, the {@code YEAR} is validated. |
| * If the mode is lenient, then the date is combined in a manner equivalent to |
| * creating a date on the first day of the requested year, then adding |
| * the difference in weeks, then in days. |
| * If the mode is smart or strict, then the all three fields are validated to |
| * their outer ranges. The date is then combined in a manner equivalent to |
| * creating a date on the first day of the requested year, then adding |
| * the amount in weeks and days to reach their values. If the mode is strict, |
| * the date is additionally validated to check that the day and week adjustment |
| * did not change the year. |
| * <li>{@code YEAR}, {@code ALIGNED_WEEK_OF_YEAR} and {@code DAY_OF_WEEK} - |
| * If all three are present, then they are combined to form a date. |
| * The approach is the same as described above for years and weeks in |
| * {@code ALIGNED_DAY_OF_WEEK_IN_YEAR}. The day-of-week is adjusted as the |
| * next or same matching day-of-week once the years and weeks have been handled. |

| * The default implementation is suitable for most calendar systems. |
| * If {@link java.time.temporal.ChronoField#YEAR_OF_ERA} is found without an {@link java.time.temporal.ChronoField#ERA} |
| * then the last era in {@link #eras()} is used. |
| * The implementation assumes a 7 day week, that the first day-of-month |
