#CALC SPREADSHEET TEXTBAR HOW TO#
Here is how to use the newly defined custom calculation engine to get desired results. If(data.getFunctionName().toUpperCase().equals("SUM")=true)ĭouble val = (double)data.getCalculatedValue() Public void calculate(CalculationData data) public class CustomEngine extends AbstractCalculationEngine Below provided is the simplest usage scenario to define a custom calculation engine that extends AbstractCalculationEngine in order to override the Excel’s default SUM function. CalculationData: Represents the required data when calculating one function, such as function name, parameters and so forth.īy implementing custom calculation engine, users can override all Excel’s native functions with more flexibility.AbstractCalculationEngine: Represents custom calculation engine to extend the default calculation engine of Aspose.Cells.Aspose.Cells for Java 8.7.2 has exposed two new classes for this purpose as detailed below. The recent revision of Aspose.Cells for Java allows to extend the default calculation engine to get desired results. However, sometimes the application requirement demands to override any Excel formula in order to get desired results, such as return 3 for function =SUM(1,1), which isn’t possible with default Aspose.Cells calculation engine. Implement Custom Calculation Engine #Īspose.Cells APIs have powerful calculation engine that can calculate almost all of the Microsoft Excel functions with precision.
