ALcyLspFormatAddOnReturns 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 ALcyLspFormat createBaseFormat() {
return new ALcyLspFormatWrapper(super.createBaseFormat()){
@Override
protected ILspLayerFactory createLayerFactory(){
final ILspLayerFactory delegate = super.createLayerFactory();
return new ILspLayerFactory(){
@Override
public boolean canCreateLayers(ILcdModel aModel){
return delegate.canCreateLayers(aModel);
}
@Override
public Collection<ILspLayer> createLayers(ILcdModel aModel){
Collection<ILspLayer> layers = delegate.createLayers(aModel);
for(ILspLayer layer : layers){
ILcdIcon icon = ...;
layer.setIcon(icon)
}
return layers;
}
}
}
}
}

ALcyLspFormatAddOnReturns a new data format wrapper for this add-on. A format wrapper extends the base format with aspects such as 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).
