Rename Baseline in Plain Java API

I want to rename a baseline (something that you can do via the client), but the IBaseline object does not seem to have a method that allows the name to be changed. 

Is this correct?  Is there another way of doing it?

   IWorkspaceManager workspaceManager = (IWorkspaceManager)repo.getClientLibrary(IWorkspaceManager.class);
   
   IComponentSearchCriteria compCrit = IComponentSearchCriteria.FACTORY.newInstance();
   compCrit.setExactName("LATF");
   List<IComponentHandle> components = workspaceManager.findComponents(compCrit,100,new SysoutProgressMonitor());
   
   IComponentHandle componentHandle = null;
   for (Iterator<IComponentHandle> ci = components.iterator(); ci.hasNext();) {
    componentHandle = (IComponentHandle)ci.next();
    IComponent component_comp = (IComponent)repo.itemManager().fetchCompleteItem(componentHandle, IItemManager.DEFAULT, new SysoutProgressMonitor()); 
    System.out.println(component_comp.getName());
   }
   
   IBaselineSearchCriteria crit1 = IBaselineSearchCriteria.FACTORY.newInstance(); 
   crit1.setExactName(oldBaseline);
   crit1.setComponentRequired(componentHandle);
   List<IBaselineHandle> baselines = workspaceManager.findBaselines(crit1,100,new SysoutProgressMonitor());
   
   for (Iterator<IBaselineHandle> bi = baselines.iterator(); bi.hasNext();) { 
    IBaselineHandle baselineHandle = (IBaselineHandle)bi.next();
    IBaseline baseline_comp = (IBaseline)repo.itemManager().fetchCompleteItem(baselineHandle, IItemManager.DEFAULT, new SysoutProgressMonitor()); 
    if (baseline_comp.getName().equals(oldBaseline)) {
     System.out.println("found");
    } 
   }
