Constructor Details

SimpleSwap

public SimpleSwap(double[] fixingDates,
 double[] paymentDates,
 double[] swaprates,
 boolean isPayFix,
 double[] notional)

Create a swap.

Parameters:

fixingDates - Vector of fixing dates

paymentDates - Vector of payment dates (must have same length as fixing dates)

swaprates - Vector of strikes (must have same length as fixing dates)

isPayFix - If true, the swap is receive float - pay fix, otherwise its receive fix - pay float.

notional - The notional as a vector for all periods

SimpleSwap

public SimpleSwap(double[] fixingDates,
 double[] paymentDates,
 double[] swaprates,
 boolean isPayFix,
 double notional)

Parameters:

fixingDates - Vector of fixing dates

paymentDates - Vector of payment dates (must have same length as fixing dates)

swaprates - Vector of strikes (must have same length as fixing dates)

isPayFix - If true, the swap is receive float - pay fix, otherwise its receive fix - pay float.

notional - The constant notional

SimpleSwap

public SimpleSwap(double[] fixingDates,

Method Details

getValue

public RandomVariable getValue(double evaluationTime,
 TermStructureMonteCarloSimulationModel model)
                        throws CalculationException

This method returns the value random variable of the product within the specified model, evaluated at a given evalutationTime. Note: For a lattice this is often the value conditional to evalutationTime, for a Monte-Carlo simulation this is the (sum of) value discounted to evaluation time. Cashflows prior evaluationTime are not considered.

Specified by:

getValue in interface TermStructureMonteCarloProduct

Specified by:

getValue in class AbstractTermStructureMonteCarloProduct

Parameters:

evaluationTime - The time on which this products value should be observed.

model - The model used to price the product.

Returns:

The random variable representing the value of the product discounted to evaluation time

Throws:

CalculationException - Thrown if the valuation fails, specific cause may be available via the cause() method.
