Constructor Details

TriggerIndex

public TriggerIndex(AbstractProductComponent trigger,
 AbstractProductComponent indexIfTriggerIsPositive,
 AbstractProductComponent indexIfTriggerIsNegative)

Creates the function trigger(t) ≥ 0.0 ? indexIfTriggerIsPositive(t) : indexIfTriggerIsNegative(t)

Parameters:

trigger - An index whose value determines which of the following indices is taken.

indexIfTriggerIsPositive - An index representing the result if trigger is non-negative (≥ 0).

indexIfTriggerIsNegative - An index representing the result if trigger is negative (< 0)

Method Details

getValue

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

Description copied from interface: TermStructureMonteCarloProduct

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 AbstractIndex

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.

queryUnderlyings

public Set<String> queryUnderlyings()

Description copied from class: AbstractProductComponent

Returns a set of underlying names referenced by this product component (i.e., required for valuation) or null if none.

Specified by:

queryUnderlyings in class AbstractProductComponent

Returns:

A set of underlying names referenced by this product component (i.e., required for valuation) or null if none.

toString

public String toString()

Overrides:
