Public Static Functions

static QStringList separatorCharacters(): returns the list of all predefined separator characters.

static QStringList commentCharacters(): returns the list of all predefined comment characters.

static size_t lineCount(const QString &fileName, size_t maxLines = std::numeric_limits<std::size_t>::max()): returns number of lines in file ‘fileName’ optional: only check ‘maxLines’ (returns minimum of line count and maxLines)

static QPair<QString, QString> dataTypeString(const DataType): returns the string representation of the given DataType.

static AbstractColumn::ColumnMode dataTypeToColumnMode(DataType): maps AsciiFilter::DataType to AbstractColumn::ColumnMode

static DataType columnModeToDataType(AbstractColumn::ColumnMode): maps AbstractColumn::ColumnMode to AsciiFilter::DataType

static bool validateDataTypes(const QStringView &s, QVector<DataType>&, QString &invalidString)

validates the provided data types string and converts it to the list of DataTypes,

Parameters:

s – the string to validate
types – the resulting list of DataTypes
invalidString – the invalid part of the provided string

Returns:

true if all provided data types are valid, false otherwise

static QVector<AbstractColumn::ColumnMode> determineColumnModes(const QVector<QStringList>&, const AsciiFilter::Properties&, QString &dateTimeFormat)

AsciiFilter::determineColumnModes.

Determines the column modes from the provided rows

Parameters:: dateTimeFormat – The datetime format will be updated if it is empty by the detected format
Returns:
