Constructor & Destructor Documentation

CSVFileReader::CSVFileReader	(	QString	path,
		CSVFormat	format,
		sv_samplerate_t	mainModelSampleRate,
		ProgressReporter *	reporter = `0`
	)

Construct a CSVFileReader to read the CSV file at the given path, with the given format.

Definition at line 47 of file CSVFileReader.cpp.

References m_device, m_error, m_filename, m_fileSize, m_reporter, and ProgressReporter::setDefinite().

CSVFileReader::CSVFileReader	(	QIODevice *	device,
		CSVFormat	format,
		sv_samplerate_t	mainModelSampleRate,
		ProgressReporter *	reporter = `0`
	)

Construct a CSVFileReader to read from the given QIODevice.

Caller retains ownership of the QIODevice: the CSVFileReader will not close or delete it and it must outlive the CSVFileReader.

Member Function Documentation

bool CSVFileReader::isOK ( ) const

overridevirtual

Return true if the file appears to be of the correct type.

The DataFileReader will be constructed by passing a file path to its constructor. If the file can at that time be determined to be not of a type that this reader can read, it should return false in response to any subsequent call to isOK().

If the file is apparently of the correct type, isOK() should return true; if it turns out that the file cannot after all be read (because it's corrupted or the detection misfired), then the read() function may return NULL.

Implements DataFileReader.

QString CSVFileReader::getError ( ) const

overridevirtual

Reimplemented from DataFileReader.

Definition at line 115 of file CSVFileReader.cpp.

References m_error.

Model * CSVFileReader::load ( ) const

overridevirtual

Read the file and return the corresponding data model.

This function is not expected to be thread-safe or reentrant. This function may be interactive (i.e. it's permitted to pop up dialogs and windows and ask the user to specify any details that can't be automatically extracted from the file).

Return NULL if the file cannot be parsed at all (although it's preferable to return a partial model and warn the user).

Caller owns the returned model and must delete it after use.

Implements DataFileReader.
