19 * This class is the main entry point for Rocksim design file imported to OpenRocket. Currently only Rocksim v9
20 * file formats are supported, although it is possible that v8 formats will work for most components.
22 * In the cases of v9 components that exist in Rocksim but have no corollary in OpenRocket a message is added to
23 * a warning set and presented to the user. In effect, this loading is a 'best-effort' mapping and is not meant to
24 * be an exact representation of any possible Rocksim design in an OpenRocket format.
26 * Rocksim simulations are not imported.
29 * Material interface (or at least make them abstract in RocketComponent)

35 * This method is called by the default implementations of {@link #load(java.io.File)}
36 * and {@link #load(java.io.InputStream)} to load the rocket.
38 * @throws net.sf.openrocket.file.RocketLoadException
39 * if an error occurs during loading.
