  public void expandDuplicates(int expandedSize, WritableChunk<? extends Attributes.Any> chunkToExpand, IntChunk<Attributes.ChunkLengths> keyRunLengths)
  
  Description copied from interface: DupExpandKernel
  
  Expands entries values from chunkToExpand in-place, using keyRunLengths to determine how many copies. The keyRunLengths chunk is parallel to the original chunkToExpand; it is never modified.
  
  Specified by:
  
  expandDuplicates in interface DupExpandKernel
  
  Parameters:
  
  expandedSize - the sum of all entries in keyRunLengths
  
  chunkToExpand - the values to expand in-place (this writable chunk must have capacity >= expandedSize)
  
  keyRunLengths - the key run-lengths parallel to chunkToExpand
- expandDuplicates
  
  public static void expandDuplicates(int expandedSize, WritableShortChunk<? extends Attributes.Any> chunkToExpand, IntChunk<Attributes.ChunkLengths> keyRunLengths)
