static QString nullRepresentation()
This string is used to represent the value NULL throughout QGIS.
QString representValue(QgsVectorLayer *layer, int fieldIndex, const QVariantMap &config, const QVariant &cache, const QVariant &value) const override
Create a pretty String representation of the value.
QString id() const override
Returns a unique id for this field formatter.
Represents a vector layer which manages a vector based data sets.
