question: protected IndexKey convertStartKeyToNodeEntry ( byte [ ] startKey ) { ByteBuffer buffer = ByteBuffer . wrap ( startKey ) ; buffer . rewind ( ) ; int dictonaryKeySize = buffer . getInt ( ) ; int nonDictonaryKeySize = buffer . getInt ( ) ; byte [ ] dictionaryKey = new byte [ dictonaryKeySize ] ; buffer . get ( dictionaryKey ) ; byte [ ] nonDictionaryKey = new byte [ nonDictonaryKeySize ] ; buffer . get ( nonDictionaryKey ) ; IndexKey entry = new IndexKey ( dictionaryKey , nonDictionaryKey ) ; return entry ; }
target:  Below method is to convert the start key into fixed and variable length key. data format<lenght><fixed length key><length><variable length key>
