  • Method Details

    • getBarrierDirection

      RandomVariableFromDoubleArray[] getBarrierDirection​(int timeIndex, RandomVariable[] randomVariable)
      The barrier direction, i.e. a (stochastic) projection vector for the components)
      Parameters:
      timeIndex - Time index associated with the model time discretization.
      randomVariable - Model process realization at timeIndex.
      Returns:
      Direction of barrier.

    • getBarrierLevel

      RandomVariable getBarrierLevel​(int timeIndex, RandomVariable[] randomVariable) throws CalculationException
      The barrier level
      Parameters:
      timeIndex - Time index associated with the model time discretization.
      randomVariable - 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

      boolean isUpperBarrier()
      Returns:
      Returns true, if the barrier is an upper barrier. Returns false, if the barrier is an lower barrier.
