Serializable, ProductInterface

public class DateIndex
extends AbstractIndex

An index whose value is a function of the fixing date, for example the DAY, MONTH or NUMBER_OF_DAYS_IN_MONTH. This index is useful in building date based interpolation formulas using other indices.

Constructor Detail

DateIndex

public DateIndex(String name,
                 String currency,
                 DateIndex.DateIndexType dateIndexType)

Construct a date index.

Parameters:

name - Name of this index.

currency - Currency (if any - in natural situations this index is a scalar).

dateIndexType - The date index type.

DateIndex

public DateIndex(String name,
                 DateIndex.DateIndexType dateIndexType)

Construct a date index.

Parameters:

name - Name of this index.

dateIndexType - The date index type.

Method Detail

getValue

public RandomVariableInterface getValue(double fixingTime,
                                        LIBORModelMonteCarloSimulationInterface model)
                                 throws CalculationException

Description copied from class: AbstractLIBORMonteCarloProduct

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 AbstractIndex

Parameters:

fixingTime - 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.
