Create a new ChunkedDoubleColumnIterator.

Parameters:

chunkSource - The ChunkSource to fetch values from; must have chunk type of ChunkType.Double

rowSequence - The RowSequence to iterate over

chunkSize - The buffer size to use when fetching data

firstRowKey - The first row key from rowSequence to iterate

length - The total number of rows to iterate

ChunkedDoubleColumnIterator

public ChunkedDoubleColumnIterator(@NotNull
