Class LuxarDeltaCodec

constructor

• new LuxarDeltaCodec(cols: number, bits: number): LuxarDeltaCodec

  Parameters

  • cols: number
  • bits: number

  Returns LuxarDeltaCodec

Readonlykind

spec

• get spec(): LuxarDeltaSpec

  The config this instance decodes with (for a fused worker decode).

  Returns LuxarDeltaSpec

StaticfromConfig

• fromConfig(config: LuxarDeltaConfig, meta: ArrayMetadata): LuxarDeltaCodec

  Parameters

  • config: LuxarDeltaConfig
  • meta: ArrayMetadata

  Returns LuxarDeltaCodec

encode

• encode(chunk: CodeChunk): CodeChunk

  Row-major codes -> columnar zigzag residuals (viewer never writes; kept for parity tests).

  Parameters

  • chunk: CodeChunk

  Returns CodeChunk

decode

• decode(chunk: CodeChunk): CodeChunk

  Columnar zigzag residuals -> row-major codes (the hot path). A chunk a data worker already delta-decoded (fused with blosc) passes through.

  Parameters

  • chunk: CodeChunk

  Returns CodeChunk

decodeResiduals

• decodeResiduals(chunk: CodeChunk): CodeChunk

  The delta decode itself — what a worker runs for a fused chunk.

  Parameters

  • chunk: CodeChunk

  Returns CodeChunk
