* own UI presentation.
 * <p>
 * The following Java element hierarchy is surfaced by this content provider:
 * <p>
 * <pre>
Java model (<code>IJavaModel</code>)
   Java project (<code>IJavaProject</code>)
      package fragment root (<code>IPackageFragmentRoot</code>)
         package fragment (<code>IPackageFragment</code>)
            compilation unit (<code>ICompilationUnit</code>)
            binary class file (<code>IClassFile</code>)
 * </pre>
 * </p> 			
 * <p>
 * Note that when the entire Java project is declared to be package fragment root,
 * the corresponding package fragment root element that normally appears between the
 * Java project and the package fragments is automatically filtered out.
 * </p>
 * This content provider can optionally return working copy elements for members 
 * below compilation units. If enabled, working copy members are returned for those
 * compilation units in the Java element hierarchy for which a shared working copy exists 
 * in JDT core.
 * 
 * @see org.eclipse.jdt.ui.IWorkingCopyProvider
