Class RawVectorParser

java.lang.Object

io.lettuce.core.output.RawVectorParser

All Implemented Interfaces:

ComplexDataParser<RawVector>

public class RawVectorParser
extends Object
implements ComplexDataParser<RawVector>

Parser for Redis VEMB command output with the RAW option.

This parser converts the response from the Redis VEMB command with the RAW option into a RawVector object, which contains the raw binary vector data along with metadata such as quantization type, normalization factor, and quantization range.

The VEMB command with RAW option returns the following data:

1. The quantization type as a string: "int8" (Q8), "float32" (NOQUANT), or "binary" (BIN)
2. A binary blob containing the raw vector data
3. The L2 norm of the vector before normalization
4. The quantization range (only for Q8 quantization)

6.7

parse

public RawVector parse(ComplexData dynamicData)

Parse the output of the Redis VEMB command with the RAW option and convert it to a RawVector object.

The VEMB command with RAW option returns an array with the following elements:

1. The quantization type as a string
2. A binary blob containing the raw vector data
3. The L2 norm of the vector before normalization
4. The quantization range (only for Q8 quantization)

Specified by:

parse in interface ComplexDataParser<RawVector>

Parameters:

dynamicData - output of VEMB command with RAW option

Returns:

a RawVector instance containing the parsed information

Throws:

IllegalArgumentException - if the input data is null, empty, or has an invalid format
