- * A limited C++ generic type. The purpose of this class is to allow C++
- * 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.
