Detailed Description

Parse the format in config file.

Attention

Specifications in config file must be in compliance with the following rules. Otherwise an exception would be thrown.

Field Name	Viable Length	Further Constraints
flowkey	4, 8, 13	Specify exactly once

Constructor & Destructor Documentation

◆ DataFormat()

OmniSketch::Data::DataFormat::DataFormat ( const toml::array & array )

Construct by specifications in config file.

It is suggested that toml::array is fetched via a call to Util::ConfigParser::parseConfig(T &, const std::string_view) const with T = toml::array.

Member Function Documentation

◆ getKeyLength()

int32_t OmniSketch::Data::DataFormat::getKeyLength ( ) const

inline

Get the key length.

◆ getRecordLength()

int32_t OmniSketch::Data::DataFormat::getRecordLength ( ) const

inline

Get the length of a record.

◆ readAsFormat()

template<int32_t key_len>

const int8_t * OmniSketch::Data::DataFormat::readAsFormat	(	Record< key_len > &	record,
		const int8_t *	byte
	)		const

Unscramble byte string in given format.

Template Parameters

key_len length of flowkey

Parameters

record	the record to be stored to
byte	pointer to byte string

Returns: pointer to the head of unprocessed byte string

Attention: An exception would be thrown if key_len does not match that in DataFormat.

◆ writeAsFormat()
