* <p>A client side editor.</p>

* <p>Editors should implement this interface in order to isolate the editor components from the editing logic (provided by drivers) and the instance edited.</p>
* <p>Editor sub-types should add more interface methods to describe the whole editor hierarchy for the instance of type <code>T</code>.</p>
* <p>
* <p>The most common edition workflow consist of:</p>
* <ol>
* <li>Create the editor implementation instance and call <code>edit()</code> using the edited instance as argument.</li>
* <li>Let the user interact with the editors and update their states.</li>
* <li>Flush the whole editors hierarchy to ensure editor's states are up to date.</li>
* <li>Obtain the edited instance member values from each editor in the hierarchy by calling <code>getValue()</code>.</li>
* <li>Validate the edited instance using any JSR303 validators for it.</li>
* <li>Set the resulting violations, if any, into the editors hierarchy to display the validation errors.</li>
* </ol>
* @param <T> The edited entity type.
* @param <A> The edited member type for this editor/sub-editor.
