使用 AbstractCalculationEngine 返回值范围

Aspose.Cells提供抽象计算引擎用于实现 Microsoft Excel 不支持的用户定义或自定义函数的类作为内置函数。

本文将解释如何从返回值的范围抽象计算引擎.

下面的代码演示了使用抽象计算引擎并通过其方法返回值的范围。

创建一个带有函数的类计算自定义函数.这个类扩展抽象计算引擎.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
import java.util.ArrayList;

import com.aspose.cells.AbstractCalculationEngine;
import com.aspose.cells.CalculationData;
import com.aspose.cells.DateTime;

public class CustomFunctionStaticValue extends AbstractCalculationEngine {
	@Override
	public void calculate(CalculationData calculationData) {
		calculationData.setCalculatedValue(new Object[][] { new Object[] { new DateTime(2015, 6, 12, 10, 6, 30), 2 },
				new Object[] { 3.0, "Test" } });
	}
}

现在在你的程序中使用上面的函数。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
String outputDir = Utils.Get_OutputDirectory();
Workbook workbook = new Workbook();
Cells cells = workbook.getWorksheets().get(0).getCells();

Cell cell = cells.get(0, 0);
cell.setArrayFormula("=MYFUNC()", 2, 2);

Style style = cell.getStyle();
style.setNumber(14);
cell.setStyle(style);

CalculationOptions copt = new CalculationOptions();
copt.setCustomEngine(new CustomFunctionStaticValue());
workbook.calculateFormula(copt);

// Save to XLSX by setting the calc mode to manual
workbook.getSettings().getFormulaSettings().setCalculationMode(CalcModeType.MANUAL);
workbook.save(outputDir + "output.xlsx");

// Save to PDF
workbook.save(outputDir + "output.pdf");
