Interface DocValuesRangeSupport

public interface DocValuesRangeSupport

Interface for SIMD-accelerated doc values range operations.

Implementations fill a FixedBitSet with the doc IDs in a range whose values satisfy a numeric range predicate. The default scalar implementation is used when the Panama Vector API is unavailable; a SIMD-accelerated implementation is used otherwise.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

Method Summary

Modifier and Type	Method	Description
void	rangeIntoBitSet(LongValues values, int fromDoc, int toDoc, long minValue, long maxValue, FixedBitSet bitSet, int offset)	Fills bitSet with the doc IDs in [fromDoc, toDoc) whose values (read via values) are in [minValue, maxValue].

Method Details

rangeIntoBitSet

void rangeIntoBitSet(LongValues values,
 int fromDoc,
 int toDoc,
 long minValue,
 long maxValue,
 FixedBitSet bitSet,
 int offset)

Fills bitSet with the doc IDs in [fromDoc, toDoc) whose values (read via values) are in [minValue, maxValue].

Parameters:

values - random-access reader for the doc values

fromDoc - first doc ID to evaluate (inclusive)

toDoc - last doc ID to evaluate (exclusive)

minValue - lower bound of the range (inclusive)

maxValue - upper bound of the range (inclusive)

bitSet - the bitset to fill

offset - subtracted from each doc ID before setting the bit
