void raw::Compress	(	std::vector< short > &	adc,
		raw::Compress_t	compress
	)

Compresses a raw data buffer.

Parameters

adc	buffer with uncompressed data
compress	type of compression to be applied

This function dispatches the compression to the function appropriate for the specified compression type. The resulting compressed data replaces the input buffer content, which is lost. Compression is expected to reduce the size of the data, so that there is in principle no need for reallocation of the input buffer, adc, to store the result.

void raw::Uncompress	(	const std::vector< short > &	adc,

		raw::Compress_t	compress
	)

Uncompresses a raw data buffer.

Parameters

adc	compressed buffer
uncompressed	buffer to be filled with uncompressed data
compress	type of compression in the adc buffer

This function dispatches the uncompression to the correct uncompress function according to compression type in compress.

The uncompressed buffer must be already allocated with enough space to store the full inflated adc data. Uncompressing raw::RawDigit can be done as follows:

std::vector<ADC_t> uncompressed(digit.Samples(), 0);
raw::Uncompress(digit.ADC(), uncompressed, digit.ADC());
