| * programs to make use of (or implement) Binder interfaces which make use |
| * the Java "Object" generic type (either via the use of the Map type or |
| * some other mechanism). |
| * |
| * This class only supports a limited set of types, but additional types |
| * may be easily added to this class in the future as needed---without |
| * breaking binary compatability. |
| * |
| * This class was written in such a way as to help avoid type errors by |
| * giving each type their own explicity-named accessor methods (rather than |
| * overloaded methods). |
| * |
| * When reading or writing this class to a Parcel, use the `writeValue()` |
| * and `readValue()` methods. |
