Member Function Documentation

readData() [1/2]

std::shared_ptr< DataFrame > inviwo::CSVReader::readData ( const std::string &  fileName )

overridevirtual

read a CSV file from a file

Parameters

fileName

name of the input CSV file

Returns

a DataFrame containing the CSV data

Exceptions

FileException	if the file cannot be accessed
CSVDataReaderException	if the file contains no data, the first row should hold column headers, but they cannot be found, or if there are unmatched quotes at the end of the file

Implements inviwo::DataReaderType< DataFrame >.

readData() [2/2]

std::shared_ptr< DataFrame > inviwo::CSVReader::readData

(

std::istream &

stream

)

const

read a CSV file from a input stream, e.g. a std::ifstream. In case file streams are used, the file must have be opened prior calling this function.

Parameters

stream

input stream with the CSV data

Returns

a DataFrame containing the CSV data

Exceptions

CSVDataReaderException

if the given stream is in a bad state, the stream contains no data, the first row should hold column headers, but they cannot be found, or if there are unmateched quotes at the end of the stream
