Constructor & Destructor Documentation

CSVReader()

CSVReader::CSVReader	(	std::string	filename,
		std::string	delm = ","
	)

Creates an instance of CSVReader.

Parameters

filename	name of file to read
delm	delimiter of columns in file.

Member Function Documentation

getData()

std::vector< std::vector< std::string > > CSVReader::getData

(

)

Reads and parses data from a CSV, ASCII or TIFF file into a 2D vector.

Checks for the existence of the input file with either a .tif or .asc extension and processes it accordingly. If the file is in CSV format, it is read line by line and split using the specified delimiter. If the file is in ASCII format, the function reads the header separately before parsing the data. If the file is in TIFF format, it extracts metadata (e.g., grid dimensions, cell size, and coordinates) and reads raster data row by row.

Returns

A 2D vector of strings containing the parsed data.

• For ASC and CSV files, each row is stored as a vector of strings.
• For TIFF files, metadata is stored in the first few rows, followed by pixel values.

Exceptions

std::runtime_error

If the file type is unsupported, memory allocation fails, or an error occurs during file reading.

parseDF()

void CSVReader::parseDF	(	inputs *	df_ptr,
		std::vector< std::vector< std::string > > &	DF,
		arguments *	args_ptr,
		int	NCells
	)

Populates an instance of inputs using information contained in a 2D vector.

Populates the inputs object df_ptr with the information found in DF. If no value is provided for a variable, then a default one is used.

Parameters

df_ptr	pointer to inputs object
DF	2D vector with input data
args_ptr	array of inputted command line arguments
NCells	number of cells

Here is the caller graph for this function:

parseNDF()

void CSVReader::parseNDF	(	std::vector< int > &	NFTypes,
		std::vector< std::vector< std::string > > &	DF,
		int	NCells
	)

Populates a vector of size NCells with fuel type number per cell.

Parameters

NFTypes	vector of fuel type per cell
DF	2D vector of input data
NCells	number of cells

Here is the caller graph for this function:

parsePROB()

void CSVReader::parsePROB	(	std::vector< float > &	probabilities,
		std::vector< std::vector< std::string > > &	DF,
		int	NCells
	)

Not currently supported. Populates a vector of size NCells with ignition probability per cell.

This is not currently supported because ignition probability is not stored in DF.

Parameters

probabilities	vector of ignition probability per cell
DF	2D vector of input data
NCells	number of cells

Here is the caller graph for this function:

printData()

void CSVReader::printData

(

std::vector< std::vector< std::string > > &

DF

)

print data contained in 2D vector to console row by row

Parameters

DF	2D vector of strings
