Method Detail

calculateDaysInPeriod

public double calculateDaysInPeriod(FISADate previousCouponDate,
                                    FISADate nextCouponDate,
                                    int interestFrequency,
                                    boolean eomAdjust)

Calculate the total number of days in a coupon period. This implementation returns calculateDays( previousCouponDate, nextCouponDate, security );

Specified by:

calculateDaysInPeriod in class DayCountBasis

Parameters:

previousCouponDate - the previous coupon date.

nextCouponDate - the next coupon date.

interestFrequency - the interestFrequency. The Act/Act implementation ignores this parameter.

eomAdjust - determines whether the end of month adjustment rule is used. The Act/Act implementation ignores this parameter.

Returns:

the number of days within the given period.

calculateDaysAccrued

public double calculateDaysAccrued(FISADate previousCouponDate,
                                   FISADate nextCouponDate,
                                   FISADate settlementDate,
                                   int interestFrequency,
                                   boolean eomAdjust)

Calculate the number of days accrued within a coupon period. This implementation returns calculateDays( previousCouponDate, settlementDate, security );

Specified by:

calculateDaysAccrued in class DayCountBasis

Parameters:

previousCouponDate - the previous coupon date.

nextCouponDate - the next coupon date.

settlementDate - the date on which settlement occurs.

interestFrequency - the interestFrequency. The Act/Act implementation ignores this parameter.

eomAdjust - determines whether the end of month adjustment rule is used. The Act/Act implementation ignores this parameter.

Returns:

the number of days accrued within the given period.

calculateDaysRemaining

public double calculateDaysRemaining(FISADate previousCouponDate,
                                     FISADate nextCouponDate,
                                     FISADate settlementDate,
                                     int interestFrequency,
                                     boolean eomAdjust)

Calculate the number of days remaining in a coupon period. This implementation returns calculateDays( settlementDate, nextCouponDate, security );

Specified by:

calculateDaysRemaining in class DayCountBasis

Parameters:

previousCouponDate - the previous coupon date.

nextCouponDate - the next coupon date.

settlementDate - the date on which settlement occurs.

interestFrequency - the interestFrequency. The Act/Act implementation ignores this parameter.

eomAdjust - determines whether the end of month adjustment rule is used. The Act/Act implementation ignores this parameter.

Returns:

the number of days remaining in the given period.

calculateDays

public double calculateDays(FISADate date1,
                            FISADate date2,
                            int interestFrequency,
                            boolean eomAdjust)

Calculates the number of days in a given period using the Actual/Actual Day Count Basis.

Specified by:

calculateDays in class DayCountBasis

Parameters:

date1 - The starting date of the period.

date2 - The ending date of the period.

interestFrequency - the interestFrequency. The Act/Act implementation ignores this parameter.

eomAdjust - determines whether the end of month adjustment rule is used. The Act/Act implementation ignores this parameter.

Returns:

the number of days within the specified period.

getDaysInYear

public int getDaysInYear(FISADate date)

Calculate the number of days for a given year.

Specified by:

getDaysInYear in class DayCountBasis

Parameters:

date - The date for which the number of days per year will be returned.

Returns:

the actual number of days in the given year if daysInYear is less than or equal to zero, otherwise returns daysInYear.
