Calculate Custom Functions in GridWeb
The following sample code adds a custom function named MYTESTFUNC() in cell B3. Then we calculate the value of this function by implementing the GridAbstractCalculationEngine interface. We calculate MYTESTFUNC() in such a way that it multiplies its parameter by 2 and returns the result. So if its parameter is 9, it will return 2 * 9 = 18.
