void util::FileIO::ListFiles	(	const std::string &	folder,
		std::vector< std::string > &	file_names,
		bool	sort = `true`
	)

static

Lists all file names in the given folder.

Parameters

folder	The folder to look into
file_names	The name of the files in the folder
sort	True, if the files should be sorted alphabetically

void util::FileIO::ReadCSV	(	Vector3d &	values,
		const std::string &	file_name,
		char	delimiter
	)

static

Reads a CSV file and stores the values in a 3D array. The first dimension is the first value of each row, used as a index to bundle multiple rows with the same first value into a single vector. The second dimension is the row in the row bundle. The third dimension is the value in that row.

Parameters

values	The 3D array of values to store the read values in
file_name	The name of the file to read
delimiter	The value delimiter of the file

void util::FileIO::ReadCSV	(	Vector2d &	values,
		const std::string &	file_name,
		char	delimiter
	)

static

Reads a CSV file and stores the values in a 2D array. The first dimension is the row and the second the value in that row.

Parameters

values	The 2D array of values to store the read values in
file_name	The name of the file to read
delimiter	The value delimiter of the file

void util::FileIO::ReadCSV	(	ValueMapVector &	values,
		const std::string &	file_name,
		char	delimiter
	)

static

Reads a CSV file. The first line of the CSV file is a header specifying the keys. The values are stored with their specified key into one map per line.

Parameters

values	A vector of maps to store the key-value pairs into
file_name	The name of the file to read
delimiter	The value delimiter of the file

void util::FileIO::ReadCSV	(	ValueMapVector &	values,
		const std::string &	header,
		const std::string &	file_name,
		char	delimiter
	)

static

Reads a CSV file. The header specifies the keys. The values are stored with their specified key into one map per line.

Parameters

values	A vector of maps to store the key-value pairs into
header	A string containing the keys separated by the delimiter
file_name	The name of the file to read
delimiter	The value delimiter of the file

static void util::FileIO::ReadTracks	(	std::vector< core::TrackletPtr > &	tracks,
		const std::string &	file_name,
		char	delimiter
	)

static

Reads the tracks from the specified file.

Parameters

tracks	A vector for storing the read tracks
file_name	The path of the file to read from
delimiter	The delimiter used to separate values

std::vector< std::string > util::FileIO::Split	(	const std::string &	input,
		char	delimiter
	)

static

Splits the input string at the delimiter and store each part into the return vector. If there is nothing between two delimiters the part will be an empty string.

Parameters

input	The string to split
delimiter	The delimiter used to split, the delimiter will not be stored

Returns: A vector of parts like (for string of length n: [0,d)...(d,d)...(d,n))

void util::FileIO::WriteCSVMatlab	(	DirectedGraph &	graph,
		const std::string &	file_name
	)

static

Writes the specified graph into a CSV file with an format readable by Matlab.

Parameters

graph	The graph to write
file_name	The name of the file to write

void util::FileIO::WriteCSVMatlab	(	MultiPredecessorMap &	map,
		Vertex &	source,
		Vertex &	sink,
		const std::string &	file_name
	)

static

Writes the specified multi predecessor map into a CSV format readable by Matlab to display all paths in the corresponding graph.

Parameters

map	The multi predecessor map to extract the paths from
source	The sink, this is the vertex where all paths begin
sink	The sink, this is the vertex where all paths end
file_name	The name of the file to write

void util::FileIO::WriteTracks	(	std::vector< core::TrackletPtr > &	tracks,
		const std::string &	file_name,
		char	delimiter
	)

static

Writes the given tracks to the given file.

Parameters

tracks	The tracks to store
file_name	The path to the file to store the tracks in
delimiter	The delimiter used to separate values
