• ### Method Detail

• #### getProcessValue

RandomVariable getProcessValue(int timeIndex,
int component)
throws CalculationException
This method returns the realization of a component of the process for a given time index.
Parameters:
timeIndex - Time index at which the process should be observed
component - Component index of the process
Returns:
The process component realizations (given as RandomVariableFromDoubleArray)
Throws:
CalculationException - Thrown if the valuation fails, specific cause may be available via the cause() method.
• #### getMonteCarloWeights

RandomVariable getMonteCarloWeights(int timeIndex)
throws CalculationException
This method returns the weights of a weighted Monte Carlo method (the probability density).
Parameters:
timeIndex - Time index at which the process should be observed
Returns:
A vector of positive weights which sums up to one
Throws:
CalculationException - Thrown if the valuation fails, specific cause may be available via the cause() method.
• #### getNumberOfComponents

int getNumberOfComponents()
Returns:
Returns the numberOfComponents.
• #### getTimeDiscretization

TimeDiscretization getTimeDiscretization()
Returns:
Returns the timeDiscretizationFromArray.
• #### getTime

double getTime(int timeIndex)
Parameters:
timeIndex - Time index.
Returns:
Returns the time for a given time index.
• #### getTimeIndex

int getTimeIndex(double time)
Returns the time index for a given simulation time.
Parameters:
time - The given simulation time.
Returns:
Returns the time index for a given time
• #### clone

Process clone()
Create and return a clone of this process. The clone is not tied to any model, but has the same process specification, that is, if the model is the same, it would generate the same paths.
Returns:
Clone of the process
