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