* Resolves parsed {@code ChronoField} values into a date during parsing.

362 |
* <p>
|
|
363 |
* Most {@code TemporalField} implementations are resolved using the
|
|
364 |
* resolve method on the field. By contrast, the {@code ChronoField} class
|
|
365 |
* defines fields that only have meaning relative to the chronology.
|
|
366 |
* As such, {@code ChronoField} date fields are resolved here in the
|
|
367 |
* context of a specific chronology.
|
|
368 |
* <p>
|
|
369 |
* {@code ChronoField} instances are resolved by this method, which may
|
|
370 |
* be overridden in subclasses.
|
|
371 |
* <ul>
|
|
372 |
* <li>{@code EPOCH_DAY} - If present, this is converted to a date and
|
|
373 |
* all other date fields are then cross-checked against the date.
|
|
374 |
* <li>{@code PROLEPTIC_MONTH} - If present, then it is split into the
|
|
375 |
* {@code YEAR} and {@code MONTH_OF_YEAR}. If the mode is strict or smart
|
|
376 |
* then the field is validated.
|
|
377 |
* <li>{@code YEAR_OF_ERA} and {@code ERA} - If both are present, then they
|
|
378 |
* are combined to form a {@code YEAR}. In lenient mode, the {@code YEAR_OF_ERA}
|
|
379 |
* range is not validated, in smart and strict mode it is. The {@code ERA} is
|
|
380 |
* validated for range in all three modes. If only the {@code YEAR_OF_ERA} is
|
|
381 |
* present, and the mode is smart or lenient, then the last available era
|
|
382 |
* is assumed. In strict mode, no era is assumed and the {@code YEAR_OF_ERA} is
|
|
383 |
* left untouched. If only the {@code ERA} is present, then it is left untouched.
|
|
384 |
* <li>{@code YEAR}, {@code MONTH_OF_YEAR} and {@code DAY_OF_MONTH} -
|
|
385 |
* If all three are present, then they are combined to form a date.
|
|
386 |
* In all three modes, the {@code YEAR} is validated.
|
|
387 |
* If the mode is smart or strict, then the month and day are validated.
|
|
388 |
* If the mode is lenient, then the date is combined in a manner equivalent to
|
|
389 |
* creating a date on the first day of the first month in the requested year,
|
|
390 |
* then adding the difference in months, then the difference in days.
|
|
391 |
* If the mode is smart, and the day-of-month is greater than the maximum for
|
|
392 |
* the year-month, then the day-of-month is adjusted to the last day-of-month.
|
|
393 |
* If the mode is strict, then the three fields must form a valid date.
|
|
394 |
* <li>{@code YEAR} and {@code DAY_OF_YEAR} -

396 |
* In all three modes, the {@code YEAR} is validated.

|
|
398 |
* creating a date on the first day of the requested year, then adding
|
|
399 |
* the difference in days.
|

404 |
* In all three modes, the {@code YEAR} is validated.

|
|
406 |
* creating a date on the first day of the first month in the requested year, then adding
|
|
407 |
* the difference in months, then the difference in weeks, then in days.
|
|
408 |
* If the mode is smart or strict, then the all four fields are validated to
|
|
409 |
* their outer ranges. The date is then combined in a manner equivalent to
|
|
410 |
* creating a date on the first day of the requested year and month, then adding
|
|
411 |
* the amount in weeks and days to reach their values. If the mode is strict,
|
|
412 |
* the date is additionally validated to check that the day and week adjustment
|

417 |
