# uproot.LZ4

Defined in uproot.compression on line 262.

Inheritance order:
uproot.compression.Compression uproot.compression._DecompressLZ4

class uproot.compression.LZ4(level)
  Parameters:

    level (int, 0-9) – Compression level: 0 is uncompressed, 1 is minimally compressed, and 9 is maximally compressed.

  Represents the LZ4 compression algorithm.

  The `cramjam` and `xxhash` libraries must be installed.

## compress

LZ4.compress(data: bytes) → bytes

## from_code

Inherited from uproot.compression.Compression.

classmethod LZ4.from_code(code)

  Constructs a uproot.compression.Compression from a raw `fCompress` integer.

## from_code_pair

Inherited from uproot.compression.Compression.

classmethod LZ4.from_code_pair(algorithm, level)

  Constructs a uproot.compression.Compression from a pair of integers representing `algorithm` and `level`.

## code

Inherited from uproot.compression.Compression.

LZ4.code

  This uproot.compression.Compression as a raw `fCompress` integer.

## code_pair

Inherited from uproot.compression.Compression.

LZ4.code_pair

  This uproot.compression.Compression as a 2-tuple of integers representing algorithm and level.

## level

Inherited from uproot.compression.Compression.

LZ4.level

  0 is uncompressed, 1 is minimally compressed, and 12 is maximally compressed.

  Type:

    The compression level

## decompress

Inherited from uproot.compression._DecompressLZ4.
