Question

Layer themeLayer = cadMapControl.getMap().getLayers().add(dataset, themeLabel, true);
String outDatasetName = memoryDatasource.getDatasets().getAvailableDatasetName(layerName);
DatasetVector datasetCAD = themeLayer.themeToDatasetVector(memoryDatasource, outDatasetName);

调用该方法，themeToDatasetVector一直卡着不动，不知道什么原因

Answer 1

你好，你说的卡住，控制台有报错信息吗？

没有任何信息返回，也没有报异常。

方便看下代码吗，全部的

public DatasetVector getThemeLabelDatasetVector(String layerName, Dataset dataset, boolean isFirst, int flag) {
        Datasource memoryDatasource = operator.getMemoryDataSource(SMGisOperator.DATASOURCE_MEMORY);
        ThemeLabel themeLabel = new ThemeLabel();
        TextStyle textStyle = new TextStyle();

        textStyle.setFontHeight(6);
        textStyle.setSizeFixed(false);
        if ("PLAN_STATION".equals(layerName) && ((flag == 1)) || flag == 2) {
            themeLabel.setLabelExpression("RES_NAME");
            themeLabel.setUniformStyle(textStyle);
            themeLabel.setOffsetX("-2");
            themeLabel.setOffsetY("2");

            //4326的地理坐标系，单位是°
            if (datasetCAD.hasPrjCoordSys()) {

                    CoordSysTransMethod.MTH_GEOCENTRIC_TRANSLATION);
            }
            //cadMapControl.getMap().getLayers().removeByDataset(datasetCAD);
            cadMapControl.getMap().getLayers().removeByDataset(dataset);
        }
        return datasetCAD;
    }

我这边测试没有问题，私信您，方便远程吗

我用这个方法不能将线数据集转为cad数据集
