+ * 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 or byte[] is already cached. The ByteString methods are used in
+ * immutable API only and byte[] methods used in mutable API only for they use
+ * different representations for string/bytes fields.
