-/**
- * Commits the contents of a working copy translation unit to its original
- * element and resource, bringing the C Model up-to-date with the current
- * contents of the working copy.
- *
- * <p>It is possible that the contents of the
- * original resource have changed since the working copy was created,
- * in which case there is an update conflict. This operation allows
- * for two settings to resolve conflict set by the <code>fForce</code> flag:<ul>
- * <li>force flag is <code>false</code> - in this case a <code>CModelException</code>
- * is thrown</li>
- * <li>force flag is <code>true</code> - in this case the contents of
- * the working copy are applied to the underlying resource even though
- * the working copy was created before a subsequent change in the
- * resource</li>
- * </ul>
- *
- * <p>The default conflict resolution setting is the force flag is <code>false</code>
- *
- * A CModelOperation exception is thrown either if the commit could not be
- * performed.
- *
- * This class is similar to the JDT CommitWorkingCopyOperation class.
