Member Function Documentation

checkExists()

void inviwo::DataReader::checkExists ( const std::filesystem::path & path ) const

protected

Verify that path exists, and throw DataReaderException if not.

Exceptions

DataReaderException

if the file is not found

getOption()

virtual std::any inviwo::DataReader::getOption ( std::string_view key )

inlinevirtual

Query the value of an reader specific option.

Parameters

key	the option to query

Returns

an std::any with the requested option or an empty std::any if the option was not found

Reimplemented in inviwo::AssimpReader, and inviwo::CSVReader.

open()

std::ifstream inviwo::DataReader::open ( const std::filesystem::path & path, std::ios_base::openmode mode = std::ios_base::in ) const

protected

Open path in mode for reading. If the file is not found or the file can't be opened an exception is thrown.

Exceptions

DataReaderException

if the file is not found, and FileException if the file can't be opened.

setOption()

virtual bool inviwo::DataReader::setOption ( std::string_view key, std::any value )

inlinevirtual

Set reader specific options See the documentation of the specific reader for the available options.

Parameters

key	the option to set
value	the new value for the option

Returns

true if the option was recognized and set, otherwise false

Reimplemented in inviwo::AssimpReader, and inviwo::CSVReader.
