| * Interface for accessing working copies of <code>ICompilationUnit</code> |

| * of an <code>IEditorInput</code>. The life cycle is as follows: |
| * <ul> |
| * <li> <code>connect</code> creates and remembers a working copy of the |
| * compilation unit which is encoded in the given editor input</li> |
| * <li> <code>getWorkingCopy</code> returns the working copy remembered on |
| * <code>connect</code></li> |
| * <li> <code>disconnect</code> destroys the working copy remembered on |
| * <code>connect</code></li> |
| * </ul> |
| * <p> |
| * In order to provide backward compatibility for clients of <code>IWorkingCopyManager</code>, extension |
| * interfaces are used to provide a means of evolution. The following extension interfaces |
| * exist: |
| * <ul> |
| * <li> {@link org.eclipse.jdt.ui.IWorkingCopyManagerExtension} since version 2.1 introducing API |
| * to set and remove the working copy for a given editor input.</li> |
| * </ul> |

| * This interface is not intended to be implemented by clients. |
