Member Function Documentation

checkOverwrite() [1/2]

void inviwo::DataWriter::checkOverwrite

(

const std::filesystem::path &

path

)

const

Verify that you don't overwrite path unless overwrite is Yes.

Exceptions

DataWriterException

if the condition is broken.

checkOverwrite() [2/2]

static void inviwo::DataWriter::checkOverwrite ( const std::filesystem::path & path, Overwrite overwrite )

static

Verify that you don't overwrite path unless overwrite is Yes.

Exceptions

DataWriterException

if the condition is broken.

getOption()

virtual std::any inviwo::DataWriter::getOption ( std::string_view key ) const

inlinevirtual

Query the value of a writer 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

open()

std::ofstream inviwo::DataWriter::open ( const std::filesystem::path & path, std::ios_base::openmode mode = std::ios_base::out ) const

protected

Open path in mode for writing. If the overwrite condition is broken or the file can't be opened an exception is thrown.

Exceptions

DataWriterException

if the condition is broken, and FileException if the file can't be opened.

setOption()

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

inlinevirtual

Set writer specific options See the documentation of the specific writer 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
