* <p>The {@code Translator} class provides a translation to interface

* for objects that do not implement interface {@code Accessible}. Assistive
* technologies can use the {@link #getAccessible getAccessible} class method of
* {@code Translator} to obtain an object that implements interface {@code Accessible}.
* If the object passed in already implements interface {@code Accessible},
* {@code getAccessible} merely returns the object.
*
* <p>An example of how an assistive technology might use the {@code Translator}
* class is as follows:
*
* <PRE>
* Accessible accessible = Translator.getAccessible(someObj);
* // obtain information from the 'accessible' object.
* </PRE>
*
* <P>Note: This implementation is missing many things and is not a recommended way
* to implement accessibility features for a toolkit. Instead of relying upon this
* code, a toolkit's components should implement interface {@code Accessible} directly.
