Example 14 with TModule

 * Returns true iff the receiving resource is in the intermediate state of having the module loaded from the index
 * (or created in some other way) but the AST is still unloaded, i.e. the contents list contains an
 * {@link #isASTProxy(EObject) AST proxy} at index 0 and a non-proxy TModule at index 1.
 * <p>
 * Some notes:
 * <ol>
 * <li>here, "loaded from description" means "loaded from IResourceDescription / IEObjectDescription" or "loaded
 * from Xtext index".
 * <li>once the resource is fully loaded, i.e. also the AST has been loaded, this method will return {@code false}.
 * <li>while in the loaded-from-description state, the {@link #isLoaded() isLoaded} flag may be {@code true} or
 * {@code false}. This means, from the outside, such a resource may seem to be loaded or unloaded.
 * </ol>
 * Thus, an N4JSResource has 4 states and the following table shows what the {@link #getContents() contents} list
 * contains in each of those states:
 * <!-- @formatter:off -->
 * <table border=1>
 * <tr><th colspan=2 rowspan=2></th><th colspan=2>isLoadedFromDescription</th></tr>
 * <tr><th>false</th><th>true</th></tr>
 * <tr><th rowspan=2>isLoaded</th><th>false</th><td>empty</td><td>AST proxy + TModule</td></tr>
 * <tr><th>true</th><td>AST + TModule</td><td>AST proxy + TModule</td></tr>
 * </table>
 * <!-- @formatter:on -->
 * Note how the {@link #isLoaded() isLoaded} flag does not have any impact on the resource's actual contents in case
 * {@code isLoadedFromDescription} is {@code true}.
