Member Function Documentation

getReaderForTypeAndExtension() [1/2]

template<typename T>

std::unique_ptr< DataReaderType< T > > inviwo::DataReaderFactory::getReaderForTypeAndExtension	(	const FileExtension &	ext,
		const std::filesystem::path &	fallbackFilePathOrExtension ) const

First look for a reader using the FileExtension ext, and if no reader was found look for a reader using the fallbackFilePathOrExtension. This is often used with a file open dialog, where the dialog will have a selectedFileExtension that will be used as ext, and the fallbackFilePathOrExtension is taken from the file to be opened. This way any selected reader will have priority over the file extension.

getReaderForTypeAndExtension() [2/2]

template<typename T>

std::unique_ptr< DataReaderType< T > > inviwo::DataReaderFactory::getReaderForTypeAndExtension

(

const std::filesystem::path &

filePathOrExtension

)

const

Return a reader matching the file extension of DataReader of type T. Does case insensitive comparison between the last part of filePathOrExtension and each registered extension. Does not check for "." before the extension, so it is valid to pass for example "png".

Parameters

filePathOrExtension

Path to file, or simply the extension.

Returns

First available DataReaderType<T> if found, nullptr otherwise.

hasKey() [1/2]

virtual bool inviwo::DataReaderFactory::hasKey ( const FileExtension & key ) const

overridevirtual

Implements inviwo::Factory< DataReader, const FileExtension & >.

hasKey() [2/2]

virtual bool inviwo::DataReaderFactory::hasKey ( std::string_view key ) const

overridevirtual

Implements inviwo::Factory< DataReader, std::string_view >.
