Method Detail

readInt

public int readInt(long index)

Description copied from class: PinotDataBitSetV2

Decode integers starting at a given index. This is efficient because of simplified bitmath.

Specified by:

readInt in class PinotDataBitSetV2

Parameters:

index - docId

Returns:

unpacked integer

readInt

public void readInt(long startIndex,
                    int length,
                    int[] out)

Description copied from class: PinotDataBitSetV2

Decode integers for a contiguous range of indexes represented by startIndex and length. This uses vectorization as much as possible for all the aligned reads and also takes care of the small byte-sized window of unaligned read.

Specified by:

readInt in class PinotDataBitSetV2

Parameters:

startIndex - start docId

length - length

out - out array to store the unpacked integers
