Method Detail

getLIBOR

RandomVariable getLIBOR(int timeIndex,
                        int liborIndex)
                 throws CalculationException

Throws:

CalculationException

getLiborPeriodDiscretization

TimeDiscretization getLiborPeriodDiscretization()

The tenor time discretization of the forward rate curve.

Returns:

The tenor time discretization of the forward rate curve.

getNumberOfLibors

int getNumberOfLibors()

Get the number of LIBORs in the LIBOR discretization.

Returns:

The number of LIBORs in the LIBOR discretization

getLiborPeriod

double getLiborPeriod(int timeIndex)

The period start corresponding to a given forward rate discretization index.

Parameters:

timeIndex - The index corresponding to a given time (interpretation is start of period)

Returns:

The period start corresponding to a given forward rate discretization index.

getLiborPeriodIndex

int getLiborPeriodIndex(double time)

Same as java.util.Arrays.binarySearch(liborPeriodDiscretization,time). Will return a negative value if the time is not found, but then -index-1 corresponds to the index of the smallest time greater than the given one.

Parameters:

time - The period start.

Returns:

The index corresponding to a given time (interpretation is start of period)

getCloneWithModifiedData

LIBORModel getCloneWithModifiedData(Map<String,Object> dataModified)
                             throws CalculationException

Create a new object implementing LIBORModel, using the new data.

Specified by:

getCloneWithModifiedData in interface ProcessModel

Specified by:

getCloneWithModifiedData in interface TermStructureModel

Parameters:

dataModified - A map with values to be used in constructions (keys are identical to parameter names of the constructors).

Returns:

A new object implementing LIBORModel, using the new data.

Throws:

CalculationException - Thrown if the valuation fails, specific cause may be available via the cause() method.
