ValidatorReturnType validate(Context *c, const ParamsMultiMap &params) const override
Performs the validation and returns the result.
QString genericValidationError(Context *c, const QVariant &errorData=QVariant()) const override
Returns a generic error message if validation failed.
ValidatorNumeric(const QString &field, const ValidatorMessages &messages=ValidatorMessages(), const QString &defValKey=QString())
Constructs a new numeric validator.
~ValidatorNumeric() override
Deconstructs the numeric validator.
Base class for all validator rules.
QString label(Context *c) const
Returns the human readable field label used for generic error messages.
void defaultValue(Context *c, ValidatorReturnType *result) const
I a defValKey has been set in the constructor, this will try to get the default value from the stash ...
QString value(const ParamsMultiMap &params) const
Returns the value of the field from the input params.
QString validationError(Context *c, const QVariant &errorData=QVariant()) const
Returns a descriptive error message if validation failed.
QString debugString(Context *c) const
Returns a string that can be used for debug output if validation fails.
The Cutelyst namespace holds all public Cutelyst API.

QMultiMap< QString, QString > ParamsMultiMap

Contains the result of a single input parameter validation.
