| void | initMetaData(FrameBlock meta) | 
| void | readExternal(ObjectInput in)Redirects the default java serialization via externalizable to our default
 hadoop writable serialization for efficient broadcast/rdd deserialization. | 
| Decoder | subRangeDecoder(int colStart,
               int colEnd,
               int dummycodedOffset)Returns a new Decoder that only handles a sub range of columns. | 
| void | writeExternal(ObjectOutput os)Redirects the default java serialization via externalizable to our default
 hadoop writable serialization for efficient broadcast/rdd serialization. |
