Detailed Description

Abstract interface for decompression algorithm providers.

This class defines the interface that all decompression algorithm implementations must implement. It provides methods for decompression operations and algorithm identification.

Member Function Documentation

algorithm()

virtual const std::string & qb::compression::decompress_provider::algorithm ( ) const

pure virtual

Get the name of the decompression algorithm.

Returns

Reference to a string containing the algorithm name

decompress()

virtual std::size_t qb::compression::decompress_provider::decompress ( const uint8_t * input, std::size_t input_size, uint8_t * output, std::size_t output_size, operation_hint hint, std::size_t & input_bytes_processed, bool & done )

pure virtual

Decompress a block of data.

Parameters

input	Pointer to the compressed input data
input_size	Size of the input data in bytes
output	Pointer to the output buffer where decompressed data will be written
output_size	Size of the output buffer in bytes
hint	Hint about whether this is the last block or more blocks will follow
input_bytes_processed	[out] Number of input bytes actually processed
done	[out] Flag indicating whether decompression is complete

Returns

Number of bytes written to the output buffer

reset()

virtual void qb::compression::decompress_provider::reset ( )

pure virtual

Reset the decompressor to its initial state.

This method should reset any internal state of the decompressor, allowing it to be reused for a new decompression stream.
