19 * Interface for accessing working copies of <code>ICompilationUnit</code>
20 * objects. The original compilation unit is only given indirectly by means
21 * of an <code>IEditorInput</code>. The life cycle is as follows:
23 * <li> <code>connect</code> creates and remembers a working copy of the
24 * compilation unit which is encoded in the given editor input</li>
25 * <li> <code>getWorkingCopy</code> returns the working copy remembered on
26 * <code>connect</code></li>
27 * <li> <code>disconnect</code> destroys the working copy remembered on
28 * <code>connect</code></li>
