The majority of formats require the same two steps for visualization on a GXY view. To visualize SQLite data:

  1. Decode the data into an ILcdModel using an ILcdModelDecoder.

  2. Create an ILcdGXYLayer for the ILcdModel and add it to the ILcdGXYView.

//First create the model
ILcdModelDecoder decoder =
    new TLcdCompositeModelDecoder(TLcdServiceLoader.getInstance(ILcdModelDecoder.class));
ILcdModel model = decoder.decode("Data/Sqlite/states.spl");

//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)

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 TLcdSpatiaLiteModelDecoder class.

This results in a SQLite layer with default styling. See Visualizing Vector Data for more information about visualizing and styling vector data.

This code snippet uses the TLcdCompositeModelDecoder, initialized with all model decoders available in the service registry.

The model decoder class that is actually responsible for decoding SQLite data is the TLcdSpatiaLiteModelDecoder.
