Parameters
- $reflectionService : ReflectionService
createValidator()
Get a validator for a given data type. Returns a validator implementing the ValidatorInterface or NULL if no validator could be resolved.
public
createValidator(string $validatorType[, array<string|int, mixed> $validatorOptions = [] ][, ServerRequestInterface $request = null ]) : ValidatorInterface|null
Parameters
- $validatorType : string
-
Either one of the built-in data types or fully qualified validator class name
- $validatorOptions : array<string|int, mixed> = []
-
Options to be passed to the validator
- $request : ServerRequestInterface = null
-
PSR-7 request object
Return values
ValidatorInterface|nullgetBaseValidatorConjunction()
Resolves and returns the base validator conjunction for the given data type.
public
getBaseValidatorConjunction(string $targetClassName[, ServerRequestInterface|null $request = null ]) : ConjunctionValidator
If no validator could be resolved (which usually means that no validation is necessary), NULL is returned.
Parameters
- $targetClassName : string
-
The data type to search a validator for. Usually the fully qualified object name
- $request : ServerRequestInterface|null = null
Return values
ConjunctionValidatorbuildBaseValidatorConjunction()
Builds a base validator conjunction for the given data type.
protected
buildBaseValidatorConjunction(ConjunctionValidator $conjunctionValidator, class-string $targetClassName, ServerRequestInterface|null $request) : void
The base validation rules are those which were declared directly in a class (typically a model) through some validate annotations on properties.
If a property holds a class for which a base validator exists, that property will be checked as well, regardless of a validation annotation.
Additionally, if a custom validator was defined for the class in question, it will be added to the end of the conjunction. A custom validator is found if it follows the naming convention "Replace '\Model' by '\Validator' and append 'Validator'".
Example: $targetClassName is TYPO3\Foo\Domain\Model\Quux, then the validator will be found if it has the name TYPO3\Foo\Domain\Validator\QuuxValidator
Parameters
- $conjunctionValidator : ConjunctionValidator
- $targetClassName : class-string
-
The data type to build the validation conjunction for. Needs to be the fully qualified class name.
- $request : ServerRequestInterface|null
