@Exported public class Translator extends AccessibleContext implements Accessible, AccessibleComponent
The Translator class provides a translation to interface
Accessible
for objects that do not implement interface Accessible. Assistive
technologies can use the getAccessible class method of
Translator to obtain an object that implements interface Accessible.
If the object passed in already implements interface Accessible,
getAccessible merely returns the object.
An example of how an assistive technology might use the Translator
class is as follows:
Accessible accessible = Translator.getAccessible(someObj);
// obtain information from the 'accessible' object.
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 Accessible directly.
