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

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

  2. Create an ILspLayer for the ILcdModel and add it to the ILspView.

//First create the model
ILcdModelDecoder decoder =
    new TLcdCompositeModelDecoder(TLcdServiceLoader.getInstance(ILcdModelDecoder.class));
ILcdModel model = decoder.decode(sourceName);

//Create a layer for the model
ILspLayer layer = createArincLayer(model);

//Add the layer to the Lightspeed view (an ILspView)

A decoded ARINC model can be:

The code to create a layer for the decoded model should deal with both scenarios:

 * The ARINC model decoder can return a single model or a model tree structure, depending on the file that gets decoded.
 * This method uses recursion to deal with both scenarios.
static ILspLayer createArincLayer(ILcdModel model) {
  //The model decoder can return a model tree node.
  //The node itself is just an empty container. We create an empty layer node for that container.
  //Then we loop over the child models (=the actual data), and create layers for those as well
  if (model instanceof ILcdModelContainer) {
    TLspLayerTreeNode node = new TLspLayerTreeNode(model);
    for (int i = 0; i < ((ILcdModelContainer) model).modelCount(); i++) {
      ILcdModel childModel = ((ILcdModelContainer) model).getModel(i);
      //Use recursion to create layers for the child models
    return node;
  } else if ("ARINC".equals(model.getModelDescriptor().getTypeName())) {
    return TLspARINCLayerBuilder.newBuilder()
  throw new IllegalArgumentException("Cannot create layer for model " + model);

The resulting layer(s) use the default styling. See the Visualizing ARINC data on a Lightspeed view reference guide for more information on how to customize the styling.

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 ARINC data is the TLcdARINCModelDecoder.
