ALcyFormatAddOnReturns a new data format for this add-on. Override this method to extend the default format with new functionality.
For example, to alter the icon of the layers of this format, you can decorate the layer factory created in the format:
@Override
protected ALcyFormat createBaseFormat() {
return new ALcyFormatWrapper(super.createBaseFormat()){
@Override
protected ILcdGXYLayerFactory createGXYLayerFactory(){
final ILcdGXYLayerFactory delegate = super.createGXYLayerFactory();
return new ILcdGXYLayerFactory(){
@Override
public ILcdGXYLayer createGXYLayer(ILcdModel aModel){
ILcdGXYLayer layer = delegate.createGXYLayer(aModel);
if (layer != null){
ILcdIcon icon = ...;
layer.setIcon(icon);
}
return layer;
}
}
}
}
}

ALcyFormatAddOnReturns a new data format wrapper for this add-on. A format wrapper extends the base format with aspects such as asynchronous painting, mutable file behavior, safe guarding, etc.
Overriding this method of an existing add-on should be done with extreme care as add-ons typically rely on the wrappers that should be present (e.g. a safe guard).
