The majority of formats require the same two steps for visualization on a GXY view. To visualize MSSQL data:
//First create the model ILcdModelDecoder decoder = new TLcdCompositeModelDecoder(TLcdServiceLoader.getInstance(ILcdModelDecoder.class)); ILcdModel model = decoder.decode("Data/MSSQL/world.mss"); //Create a layer for the model with default styling ILcdGXYLayer layer = TLcdGXYLayer.create(model); //Wrap the layer with an async layer wrapper to ensure //that the view remains responsive while data is being painted layer = ILcdGXYAsynchronousLayerWrapper.create(layer); //Add the async layer to the GXY view (an ILcdGXYView) view.addGXYLayer(layer);
The file passed to the model decoder is a Java
Properties file. It contains all the information that the model decoder requires to connect to the database.
For example, the file specifies the location of the database, which table to use, and so on.
The content of that properties file is documented in the class javadoc of the
This results in a MSSQL layer with default styling. See Visualizing Vector Data for more information about visualizing and styling vector data.
