Constructor Detail

Caplet

public Caplet(double maturity,
              double periodLength,
              double strike,
              boolean isFloorlet)

Create a caplet or a floorlet. A caplet pays \( max(L-K,0) * periodLength \) at maturity+periodLength where L is fixed at maturity. A floorlet pays \( -min(L-K,0) * periodLength \) at maturity+periodLength where L is fixed at maturity.

Parameters:

maturity - The fixing date given as double. The payment is at the period end.

periodLength - The length of the forward rate period.

strike - The strike given as double.

isFloorlet - If true, this object will represent a floorlet, otherwise a caplet.

Caplet

public Caplet(double maturity,
              double periodLength,
              double strike)

Create a caplet. A caplet pays \( max(L-K,0) * periodLength \) at maturity+periodLength where L is fixed at maturity.

Parameters:

maturity - The fixing date given as double. The payment is at the period end.

periodLength - The length of the forward rate period.

strike - The strike given as double.

Method Detail

getValue

public RandomVariableInterface getValue(double evaluationTime,
                                        LIBORModelMonteCarloSimulationInterface 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 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.
