Class DayCountBasis

java.lang.Object
  com.imsl.finance.DayCountBasis

public class DayCountBasis
extends Object

The Day Count Basis. Rules for computing the number or days between two dates or number of days in a year. For many securities, computations are based on rules other than on the actual calendar.

Field Summary

static DayCountBasis	Basis30e360 Computations based on the assumption of 30 days per month and 360 days per year.
static DayCountBasis	BasisActual360 Computations are based on the number of days in a month based on the actual calendar value and the number of days, but assuming 360 days per year.
static DayCountBasis	BasisActual365 Computations are based on the number of days in a month based on the actual calendar value and the number of days, but assuming 365 days per year.
static DayCountBasis	BasisActualActual Computations are based on the actual calendar.
static DayCountBasis	BasisNASD Computations based on the assumption of 30 days per month and 360 days per year.
static BasisPart	BasisPart30E360 Computations based on the assumption of 30 days per month and 360 days per year.
static BasisPart	BasisPart365 Computations based on the assumption of 365 days per year.
static BasisPart	BasisPartActual Computations are based on the actual calendar.
static BasisPart	BasisPartNASD Computations based on the assumption of 30 days per month and 360 days per year.

Constructor Summary

DayCountBasis(BasisPart monthBasis, BasisPart yearBasis)
Creates a new DayCountBasis.

Method Summary

BasisPart	getMonthBasis() Returns the (days in month) portion of the Day Count Basis.
BasisPart	getYearBasis() Returns the (days in year) portion of the Day Count Basis.

BasisPart30E360

public static final BasisPart BasisPart30E360

Computations based on the assumption of 30 days per month and 360 days per year. This computes the number of days between two dates differently than BasisPartNASD for months with other than 30 days.

BasisPart365

public static final BasisPart BasisPart365

Computations based on the assumption of 365 days per year.

BasisPartActual

public static final BasisPart BasisPartActual

Computations are based on the actual calendar.

BasisPartNASD

public static final BasisPart BasisPartNASD

Computations based on the assumption of 30 days per month and 360 days per year.

Constructor Detail

DayCountBasis

public DayCountBasis(BasisPart monthBasis,
                     BasisPart yearBasis)

Creates a new DayCountBasis.

Parameters:

monthBasis - a BasisPart that contains the month basis

yearBasis - a BasisPart that contains the year basis

Method Detail

getMonthBasis

public BasisPart getMonthBasis()

Returns the (days in month) portion of the Day Count Basis.

Returns:

a BasisPart object which represents the month Basis for this DayCountBasis

getYearBasis

public BasisPart getYearBasis()

Returns the (days in year) portion of the Day Count Basis.

Returns:

a BasisPart object which represents the year Basis for this DayCountBasis
