Method Summary

Modifier and Type	Method	Description
`<T extends Attributes.Any> void`	`conditionalCopy(WritableChunk<T> output, Object baseInput, Object overInput, long[] useOverInput, int srcOffset, int dstOffset, int length)`	Copy values from baseInput / overInput into output.
`static CopyKernel`	`makeCopyKernel(ChunkType chunkType)`

Method Details
- makeCopyKernel
  
  static CopyKernel makeCopyKernel(ChunkType chunkType)
- conditionalCopy
  
  <T extends Attributes.Any> void conditionalCopy(WritableChunk<T> output, Object baseInput, Object overInput, long[] useOverInput, int srcOffset, int dstOffset, int length)
  
  Copy values from baseInput / overInput into output.
  Pseudo-implementation: output[i] = useOverInput.forBit(i) ? overInput[i] : baseInput[i];
  Note that useOverInput should cover the same data range as baseInput such that useOverInput.length == (overInput.length + 63) / 64 is true.
  
  Parameters:
  
  output - the output chunk
  
  baseInput - the input array to use when bit in useOverInput is zero (array)
  
  overInput - the input array to use when bit in useOverInput is one (array)
  
  useOverInput - the bitset array to indicate whether to use baseInput or overInput for each element
  
  srcOffset - the offset in baseInput/overInput
  
  dstOffset - the offset in output
  
  length - the number of elements to copy
