| DecoderRecode() | 
| Modifier and Type | Method and Description | 
|---|---|
| FrameBlock | decode(MatrixBlock in,
      FrameBlock out)Block decode API converting a matrix block into a frame block. | 
| void | initMetaData(FrameBlock meta) | 
| static void | parseRecodeMapEntry(String entry,
                   Pair<String,String> pair)Parses a line of <token, ID, count> into <token, ID> pairs, where 
 quoted tokens (potentially including separators) are supported. | 
| 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 out)Redirects the default java serialization via externalizable to our default
 hadoop writable serialization for efficient broadcast/rdd serialization. |
