/** |
* An interface extending List<String> that also provides access to the |
* items of the list as UTF8-encoded ByteString objects. This is used by the |
* protocol buffer implementation to support lazily converting bytes parsed |
* over the wire to String objects until needed and also increases the |
* efficiency of serialization if the String was never requested as the |
* ByteString is already cached. |
* <p> |
* This only adds additional methods that are required for the use in the |
* protocol buffer code in order to be able successfuly round trip byte arrays |
* through parsing and serialization without conversion to strings. It's not |
* attempting to support the functionality of say List<ByteString>, hence |
* why only these two very specific methods are added. |
