Base class for all validator rules.
QString label(Context *c) const
Returns the human readable field label used for generic error messages.
QString value(const ParamsMultiMap &params) const
Returns the value of the field from the input params.
ValidatorReturnType validate(Context *c, const ParamsMultiMap &params) const override
Performs the validation and returns the result.
QString field() const
