### Question:
MetaverseUtil { public static void enhanceVertex( Vertex vertex ) { String type = vertex.getProperty( DictionaryConst.PROPERTY_TYPE ); String localizedType = Messages.getString( MESSAGE_PREFIX_NODETYPE + type ); if ( !localizedType.startsWith( MESSAGE_FAILED_PREFIX ) ) { vertex.setProperty( DictionaryConst.PROPERTY_TYPE_LOCALIZED, localizedType ); } String category = DictionaryHelper.getCategoryForType( type ); vertex.setProperty( DictionaryConst.PROPERTY_CATEGORY, category ); String color = DictionaryHelper.getColorForCategory( category ); vertex.setProperty( DictionaryConst.PROPERTY_COLOR, color ); String localizedCat = Messages.getString( MESSAGE_PREFIX_CATEGORY + category ); if ( !localizedCat.startsWith( MESSAGE_FAILED_PREFIX ) ) { vertex.setProperty( DictionaryConst.PROPERTY_CATEGORY_LOCALIZED, localizedCat ); } }  static IDocumentController getDocumentController(); static void setDocumentController( IDocumentController docController ); static IDocument createDocument(
    INamespace namespace,
    Object content,
    String id,
    String name,
    String extension,
    String mimeType ); static void addLineageGraph( final IDocument document, Graph graph ); static void enhanceEdge( Edge edge ); static void enhanceVertex( Vertex vertex ); static Operations convertOperationsStringToMap( String operations ); static Runnable getAnalyzerRunner( final IDocumentAnalyzer analyzer, final IDocument document ); static void delay(); static final String MESSAGE_PREFIX_NODETYPE; static final String MESSAGE_PREFIX_LINKTYPE; static final String MESSAGE_PREFIX_CATEGORY; static final String MESSAGE_FAILED_PREFIX; }### Answer:
@Test public void testEnhanceVertex() { Graph graph = new TinkerGraph(); Vertex v1 = graph.addVertex( 1 ); MetaverseUtil.enhanceVertex( v1 ); }
