Member Function Documentation

bool QgsVariantUtils::isNull ( const QVariant & variant )

static

Returns true if the specified variant should be considered a NULL value.

This method is more rigorous vs QVariant::isNull(), which will return false on newer Qt versions for tests like QVariant( QDateTime() ).isNull().

		QVariant::Type	subType = `QVariant::Type::Invalid`
	)

The optional subType can be used to specify the type of variant list or map values.
