Method Detail

getBarrierDirection

public RandomVariableFromDoubleArray[] getBarrierDirection(int timeIndex,
                                                           RandomVariable[] realizationPredictor)

Description copied from interface: Barrier

The barrier direction, i.e. a (stochastic) projection vector for the components)

Specified by:

getBarrierDirection in interface Barrier

Parameters:

timeIndex - Time index associated with the model time discretization.

realizationPredictor - Model process realization at timeIndex.

Returns:

Direction of barrier.

getBarrierLevel

public RandomVariableFromDoubleArray getBarrierLevel(int timeIndex,
                                                     RandomVariable[] realizationPredictor)
                                              throws CalculationException

Description copied from interface: Barrier

The barrier level

Specified by:

getBarrierLevel in interface Barrier

Parameters:

timeIndex - Time index associated with the model time discretization.

realizationPredictor - Model process realization at timeIndex.

Returns:

Level of barrier.

Throws:

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

isUpperBarrier

public boolean isUpperBarrier()

Specified by:

isUpperBarrier in interface Barrier

Returns:

Returns true, if the barrier is an upper barrier. Returns false, if the barrier is an lower barrier.
