Interface DocValuesBulkDecodeSupport

public interface DocValuesBulkDecodeSupport
Interface for SIMD-accelerated doc values bulk decode operations.

Implementations decode byte-aligned packed numeric values into a long[] destination. 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.

      void decodeByteAligned(byte[] bytes, int bytesOffset, int bitsPerValue, long[] values, int valuesOffset, int count)
      Decodes count byte-aligned packed values from bytes into values.
      Parameters:
      bytes - source bytes encoded like LongValues produced by packed DirectReader
      bytesOffset - first byte to read
      bitsPerValue - number of bits per value, must be a multiple of 8
      values - destination values
      valuesOffset - first destination slot
      count - number of values to decode
