ActivePivot:将CellSetDTO对象转换为csv,excel或其他格式的任何代码?

标签: activepivot

我是activePivot的新手。我们调用了一个mdx查询并返回了一个CellSetDTO。是否有可用于将此CellSetDTO对象转换为CSV,Excel或其他类型格式的库代码?

我正在查看CellSetDTO类中来自quartetfs的javadoc,但javaDoc没有描述。或者,我可以编写自己的代码来生成CSV,但由于我是新手,并且没有关于javaDoc的描述,因此有点难以启动。

赞赏任何指向任何文档的指针。

谢谢你, 格雷斯

您可以使用可在沙箱项目中找到的示例,请参阅CellSetPrinter类,在构造函数arg中设置CellSetDTO。 请参阅CellSetPrinter类:

public class CellSetPrinter {

protected final CellSetDTO cellSet;

protected final AxisDTO slicer;

protected final List<AxisDTO> axes;

protected final List<CellDTO> cells;

public CellSetPrinter(CellSetDTO cellSet) {
    this.cellSet = cellSet;
    this.axes = cellSet.getAxes().getAxis();
    this.slicer = cellSet.getSlicerAxis();
    this.cells = cellSet.getCells().getCell();
}

/**
 * Compute axis positions from the cell ordinal with the classic formula:
 * <ul>
 * <li>(x0, x1, x2) -> x0 + x1 * n0 + x2 * n1 * n2
 * <li>ordinal -> (ordinal % n0, (ordinal / n0) % n1, (ordinal / (n0*n1)) % n2)
 * </ul>
 * 
 * @param ordinal
 * @return tuple expressed by coordinates
 */
protected List<String> getTuple(int ordinal) {
    List<String> tuple = new ArrayList<>();

    // Lookup positions on axes
    final int[] axisCoordinates = new int[axes.size()];

    int coeff = 1;
    for(int a = 0; a < axisCoordinates.length; a++) {
        int positionCount = axes.get(a).getPositions().getPosition().size();
        axisCoordinates[a] = (ordinal / coeff) % positionCount;
        coeff *= positionCount;
    }

    for(int a = 0; a < axisCoordinates.length; a++) {
        AxisPositionDTO position = axes.get(a).getPositions().getPosition().get(axisCoordinates[a]);
        for(MemberDTO member : position.getMembers().getMember()) {
            for(String pathElement : member.getPath().getItems().getItem()) {
                if(!"AllMember".equals(pathElement)) {
                    tuple.add(pathElement);
                }
            }
        }
    }

    // Append slicer content
    for(AxisPositionDTO position : slicer.getPositions().getPosition()) {
        for(MemberDTO member : position.getMembers().getMember()) {
            for(String pathElement : member.getPath().getItems().getItem()) {
                if(!"AllMember".equals(pathElement)) {
                    tuple.add(pathElement);
                }
            }
        }
    }
    return tuple;
}

public void print(PrintStream out) {
    for(CellDTO cell : cells) {
        System.out.println(getTuple(cell.getOrdinal()) + " " + cell.getFormattedValue());
    }
}
}
