Constructor Detail

SwaptionSimple

public SwaptionSimple(double swaprate,
                      TimeDiscretization swapTenor)

Note: It is implicitly assumed that swapTenor[0] is the exercise date (no forward starting).

Parameters:

swaprate - The strike swaprate of the swaption.

swapTenor - The swap tenor in doubles.

SwaptionSimple

public SwaptionSimple(double swaprate,
                      double[] swapTenor,
                      Swaption.ValueUnit valueUnit)

Note: It is implicitly assumed that swapTenor[0] is the exercise date (no forward starting).

Parameters:

swaprate - The strike swaprate of the swaption.

swapTenor - The swap tenor in doubles.

valueUnit - See getValue(AbstractLIBORMarketModel model)

Method Detail

getValue

public RandomVariable getValue(double evaluationTime,
                               LIBORModelMonteCarloSimulationModel 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 AbstractLIBORMonteCarloProduct

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.
