Constructor Detail

IndexedValue

public IndexedValue(double exerciseDate,
                    AbstractProductComponent index,
                    AbstractProductComponent underlying)

Creates the function J(t) V(t), where J(t) = E(I(t)|F_t) for the given I(t).

Parameters:

exerciseDate - The time t at which the index I is requested (and to which it is conditioned if necessary).

index - The index I.

underlying - The value V.

Method Detail

getCurrency

public java.lang.String getCurrency()

Description copied from class: AbstractMonteCarloProduct

Returns the currency string of this notional.

Overrides:

getCurrency in class AbstractMonteCarloProduct

Returns:

the currency

queryUnderlyings

public java.util.Set<java.lang.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.

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. Cash flows 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.
