Member Function Documentation

nextSequence()

void nextSequence ( Real  tmax = QL_MAX_REAL )

overridevirtual

Generate a sequence of random default times, one for each name in the pool, and store the result in the Pool using method setTime(name). tmax denotes the maximum relevant time- default times > tmax are not computed but set to tmax + 1 instead to save coputation time.
