Interface FwDateConstantsIF

All Known Subinterfaces:

FwDateIF

All Known Implementing Classes:

FwDate

public interface FwDateConstantsIF

I define some constants that are useful with dates. These constants are defined here rather than in the FwDateIF so that classes that want to "import" these constants into their namespace can just say "implements FwDateConstantsIF".

Field Summary

static int	DOW_FRIDAY
static int	DOW_MONDAY
static int	DOW_SATURDAY
static int	DOW_SUNDAY Day of week values.
static int	DOW_THURSDAY
static int	DOW_TUESDAY
static int	DOW_WEDNESDAY
static int	FIRST_DAY_OF_WEEK The day of week of January 1st of the FIRST_YEAR.
static int	FIRST_YEAR This is the earliest year that is considered valid for FwDates.
static java.lang.String	GMT_TIME_ZONE_ID TIME ZONE
static int	LAST_YEAR This is the last year that is considered valid for FwDates.

FIRST_YEAR

public static final int FIRST_YEAR

This is the earliest year that is considered valid for FwDates. Although the FwDate.year can be set to any value the isValid() method will return false if the year is less than FIRST_YEAR. Also, date computations like addDay() and isBefore() are only guaranteed to work if FIRST_YEAR <= year <= LAST_YEAR.

This is the last year that is considered valid for FwDates. Although the FwDate.year can be set to any value the isValid() method will return false if the year is greater than LAST_YEAR. Also, date computations like addDay() and isBefore() are only guaranteed to work if FIRST_YEAR <= year <= LAST_YEAR.
