public interface AssetModelMonteCarloSimulationInterface
extends MonteCarloSimulationInterface

Basic interface which has to be implemented by Monte Carlo models for asset processes. This interface serves as an abstraction layer between models and simulations (providing the implementation of this interface) and products (using an object implementing this interface in its valuation code, without further knowledge of the specific model and simulation technique.

Method Detail

getNumberOfAssets

int getNumberOfAssets()

Returns the number of asset price processes.

Returns:

The number of asset price processes

getAssetValue

RandomVariableInterface getAssetValue(int timeIndex,
                                      int assetIndex)
                               throws CalculationException

Returns the random variable representing the asset's value at a given time for a given asset.

Parameters:

timeIndex - Index of simulation time

assetIndex - Index of the asset (0 for a single asset model)

Returns:

The asset process as seen on simulation time

Throws:

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

getAssetValue

RandomVariableInterface getAssetValue(double time,
                                      int assetIndex)
                               throws CalculationException

Returns the random variable representing the asset's value at a given time for a given asset.

Parameters:

time - Simulation time

assetIndex - Index of the asset (0 for a single asset model)

Returns:

The asset process as seen on simulation time

Throws:

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

getNumeraire

RandomVariableInterface getNumeraire(int timeIndex)
                              throws CalculationException

Returns the numeraire associated with the valuation measure used by this model.

Parameters:

timeIndex - The time index (associated with this models time discretization).

Returns:

The numeraire associated with the valuation measure used by this model.

Throws:

CalculationException - Thrown if calculation of numeraire fails.

getNumeraire

RandomVariableInterface getNumeraire(double time)
                              throws CalculationException

Returns the numeraire associated with the valuation measure used by this model.

Parameters:

time - The time for which the numeraire is requested.

Returns:

The numeraire associated with the valuation measure used by this model.

Throws:

CalculationException - Thrown if calculation of numeraire fails.

getCloneWithModifiedData

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

Create a clone of this simulation modifying some of its properties (if any).

Specified by:

getCloneWithModifiedData in interface MonteCarloSimulationInterface

Parameters:

dataModified - The data which should be changed in the new model

Returns:

Returns a clone of this model, with some data modified (then it is no longer a clone :-)

Throws:

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

getCloneWithModifiedSeed

AssetModelMonteCarloSimulationInterface getCloneWithModifiedSeed(int seed)

Create a clone of the object implementing AssetModelMonteCarloSimulationInterface using a different Monte-Carlo seed.

Parameters:

seed - The seed of the underlying random number generator.

Returns:

Returns a clone of this model except for a modified Monte-Carlo seed.
