CompressBlock()

Compression::CompressionResultData CompressionLZ4::CompressorLZ4::CompressBlock ( AZStd::span< AZStd::byte >  compressionBuffer, const AZStd::span< const AZStd::byte > &  uncompressedData, const Compression::CompressionOptions &  compressionOptions = {}  ) const

overridevirtual

Compresses the uncompressed data into the compressed buffer

Returns

a CompressionResultData instance to indicate if compression operation has succeeded

Implements Compression::ICompressionInterface.

CompressBound()

size_t CompressionLZ4::CompressorLZ4::CompressBound ( size_t  uncompressedBufferSize ) const

overridevirtual

Returns the upper bound on compressed size given the uncompressed buffer size Can be used to allocate a destination buffer that can fit the compressed content

Parameters

uncompressedBufferSize

size of uncompressed data

Returns

worst case(upper bound) size that is needed to store compressed data for a given uncompressed size

Implements Compression::ICompressionInterface.

GetCompressionAlgorithmId()

Compression::CompressionAlgorithmId CompressionLZ4::CompressorLZ4::GetCompressionAlgorithmId ( ) const

overridevirtual

GetCompressionAlgorithmName()

AZStd::string_view CompressionLZ4::CompressorLZ4::GetCompressionAlgorithmName ( ) const

overridevirtual

Retrieves the human readable associated with the LZ4 compressor.
