Detailed Description

Tries to convert the input parameter value into the integer type specified in the constructor. If the input value does not fit into the type, the validation fails.

Note
Conversion of numeric input values is performed in the 'C' locale.
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 an integer type set in the constructor.

Validator for general usage of validators.

Constructor & Destructor Documentation

◆ ValidatorInteger()

ValidatorInteger::ValidatorInteger ( const QString field,
QMetaType::Type  type = QMetaType::ULongLong,
const ValidatorMessages messages = {},
const QString defValKey = {} 
)
explicit

Constructs a new ValidatorInteger object with the given parameters.

Parameters
fieldName of the input field to validate.
typeThe type the integer value should fit in. Only integer types are supported, everything else will generate a validation data error.
messagesCustom error message if validation fails.
defValKeyStash key containing a default value if input field is empty. This value will NOT be validated.

Definition at line 10 of file validatorinteger.cpp.

◆ ~ValidatorInteger()

ValidatorInteger::~ValidatorInteger ( )
overridedefault

Destroys the ValidatorInteger object.

Member Function Documentation

◆ genericValidationError()

◆ validate()

◆ validateCb()

void ValidatorInteger::validateCb ( Context c,
const ParamsMultiMap params,
ValidatorRtFn  cb 
) const
overrideprotectedvirtual

Performs the validation on the input params and calls the cb with the ValidatorReturnType as argument.

If validation succeeded, ValidatorReturnType::value will contain the input paramter value as the type set in the constructor.
