Detailed Description

class JsonFilter : public AbstractFileFilter 

Manages the import/export of data from/to a file formatted using JSON.

Public Functions

void readDataFromDevice(QIODevice &device, AbstractDataSource*, ImportMode = ImportMode::Replace, int lines = -1): reads the content of the device device.

virtual void readDataFromFile(const QString &fileName, AbstractDataSource* = nullptr, ImportMode = ImportMode::Replace) override: reads the content of the file fileName.

virtual void write(const QString &fileName, AbstractDataSource*) override: writes the content of the data source dataSource to the file fileName.

virtual void save(QXmlStreamWriter*) const override: Saves as XML.

virtual bool load(XmlStreamReader*) override: Loads from XML.

Public Static Functions

static QStringList dataTypes(): returns the list of all predefined data types.

static QStringList dataRowTypes(): returns the list of all predefined data row types.
