35/**
36 * <p>The Translator class provides a translation to interface Accessible
37 * for objects that do not implement interface Accessible.  Assistive
38 * technologies can use the 'getAccessible' class method of Translator to
39 * obtain an object that implements interface Accessible.  If the object
40 * passed in already implements interface Accessible, getAccessible merely
41 * returns the object.
42 *
43 * <p>An example of how an assistive technology might use the Translator
44 * class is as follows:
45 *
46 * <PRE>
47 *    Accessible accessible = Translator.getAccessible(someObj);
48 *    // obtain information from the 'accessible' object.
49 * </PRE>
50 *
51 * <P>This class extends the Translator class to provide specific support
52 * for the List class.  Translator.getAccessible() will automatically
53 * load this class when an assistive technology asks for an accessible
54 * translator for List.
