Detailed Description

This uses QHostAddress internally to check if the field contains a valid IP address. You can use the constraints flags to limit the validator to specific address ranges.

Note

Unless validation is started with NoTrimming, whitespaces will be removed from the beginning and the end of the input value before validation. If the field's value is empty or if the field is missing in the input data, the validation will succeed without performing the validation itself. Use one of the required validators to require the field to be present and not empty.

Return type

On success, ValidatorReturnType::value will contain a QString.

Member Enumeration Documentation

Constraint

enum Cutelyst::ValidatorIp::Constraint

Enumerator
NoConstraint	No address range limit.
IPv4Only	Only IPv4 addresses are valid.
IPv6Only	Only IPv6 addresses are valid.
NoPrivateRange	Addresses from private networks like 192.168.0.0/12 and fe80::/10 are invalid.
NoReservedRange	Addresses from reserved networks like 192.88.99.0/24 and 2001:db8::/32 are invalid.
NoMultiCast	Multicast addresses are invalid.
PublicOnly	Combines NoPrivateRange, NoReservedRange and NoMultiCast.

Constructor & Destructor Documentation

ValidatorIp()

ValidatorIp::ValidatorIp	(	const QString &	field,
		Constraints	constraints = NoConstraint,
		const ValidatorMessages &	messages = ValidatorMessages(),
		const QString &	defValKey = QString() )

Constructs a new ValidatorIp object with the given parameters.

Parameters

field	Name of the input field to validate.
constraints	Optional validation constraints.
messages	Custom error message if validation fails.
defValKey	Stash key containing a default value if input field is empty. This value will NOT be validated.

genericValidationError()

QString ValidatorIp::genericValidationError ( Context * c, const QVariant & errorData = QVariant() ) const

Returns a generic error message if validation failed.

Reimplemented from Cutelyst::ValidatorRule.

validate()

ValidatorReturnType ValidatorIp::validate ( Cutelyst::Context * c, const ParamsMultiMap & params ) const

overrideprotectedvirtual

Performs the validation on the input params and returns the result.

If validation succeeded, ValidatorReturnType::value will contain the input paramter value as QString.

Implements Cutelyst::ValidatorRule.
