包路径：org.joda.time.DateTime
类名称：DateTime
方法名：withField

DateTime.withField介绍

[英]Returns a copy of this datetime with the specified field set to a new value.

For example, if the field type is hourOfDay then the hour of day field would be changed in the returned instance. If the field type is null, then this is returned.

These three lines are equivalent:

DateTime updated = dt.withField(DateTimeFieldType.dayOfMonth(), 6); 
DateTime updated = dt.dayOfMonth().setCopy(6); 
DateTime updated = dt.property(DateTimeFieldType.dayOfMonth()).setCopy(6);

[中]返回此datetime的副本，并将指定字段设置为新值。
例如，如果字段类型为hourOfDay，则返回实例中的小时字段将发生更改。如果字段类型为空，则返回this。
这三条线是等效的：

DateTime updated = dt.withField(DateTimeFieldType.dayOfMonth(), 6); 
DateTime updated = dt.dayOfMonth().setCopy(6); 
DateTime updated = dt.property(DateTimeFieldType.dayOfMonth()).setCopy(6);

protected DateTime every(DateTime currentTime, DateTimeFieldType unit, int offset, int interval) {
  DateTime d = currentTime.property(unit).roundFloorCopy();
  d = d.withFieldAdded(unit.getDurationType(), offset);
  return d.withField(unit, (d.get(unit) / interval) * interval);
}
