CalculationSettings GetAdditionalIsValidTriggers Method TIBCO Spotfire 6.5 API Reference
If a subclass has additional dependencies besides those added to the baseclass this method can be overridden to indicate when the input to the calculation has changed/disappeared so the calculation can no longer produce a sensible result. This will trigger the Calculation.HasValidValue property and cause invalid columns to be output the next time the calculation is run.
