class ValidationVisitor implements ValidationVisitorInterface, GlobalExecutionContextInterface
deprecated
Default implementation of {@link ValidationVisitorInterface} and {@link GlobalExecutionContextInterface}.
__construct(mixed $root, MetadataFactoryInterface $metadataFactory, ConstraintValidatorFactoryInterface $validatorFactory, TranslatorInterface $translator, string|null $translationDomain = null, array $objectInitializers = array()) Creates a new validation visitor. | ||
visit(MetadataInterface $metadata, mixed $value, string $group, string $propertyPath) Validates a value against the constraints defined in some metadata. | ||
validate(mixed $value, string $group, string $propertyPath, bool $traverse = false, bool $deep = false) Validates a value. | ||
ConstraintViolationListInterface | getViolations() Returns the violations generated by the validator so far. | |
mixed | getRoot() Returns the value at which validation was started in the object graph. | |
ValidationVisitorInterface | getVisitor() Returns the visitor instance used to validate the object graph nodes. | |
ConstraintValidatorFactoryInterface | getValidatorFactory() Returns the factory for constraint validators. | |
MetadataFactoryInterface | getMetadataFactory() Returns the factory for validation metadata objects. |
Creates a new validation visitor.
mixed | $root | The value passed to the validator. |
MetadataFactoryInterface | $metadataFactory | The factory for obtaining metadata instances. |
ConstraintValidatorFactoryInterface | $validatorFactory | The factory for creating constraint validators. |
TranslatorInterface | $translator | The translator for translating violation messages. |
string|null | $translationDomain | The domain of the translation messages. |
array | $objectInitializers | The initializers for preparing objects before validation. |
UnexpectedTypeException | If any of the object initializers is not an instance of ObjectInitializerInterface |
Validates a value against the constraints defined in some metadata.
This method implements the Visitor design pattern. See also {@link ValidationVisitorInterface}.
MetadataInterface | $metadata | The metadata holding the constraints. |
mixed | $value | The value to validate. |
string | $group | The validation group to validate. |
string | $propertyPath | The current property path in the validation graph. |
Validates a value.
If the value is an array or a traversable object, you can set the parameter $traverse to true in order to run through the collection and validate each element. If these elements can be collections again and you want to traverse them recursively, set the parameter $deep to true as well.
If you set $traversable to true, the visitor will nevertheless try to find metadata for the collection and validate its constraints. If no such metadata is found, the visitor ignores that and only iterates the collection.
If you don't set $traversable to true and the visitor does not find metadata for the given value, it will fail with an exception.
mixed | $value | The value to validate. |
string | $group | The validation group to validate. |
string | $propertyPath | The current property path in the validation graph. |
bool | $traverse | Whether to traverse the value if it is traversable. |
bool | $deep | Whether to traverse nested traversable values recursively. |
NoSuchMetadataException | If no metadata can be found for the given value. |
Returns the violations generated by the validator so far.
ConstraintViolationListInterface | A list of constraint violations. |
Returns the value at which validation was started in the object graph.
mixed | The root value. |
Returns the visitor instance used to validate the object graph nodes.
ValidationVisitorInterface | The validation visitor. |
Returns the factory for constraint validators.
ConstraintValidatorFactoryInterface | The constraint validator factory. |
Returns the factory for validation metadata objects.
MetadataFactoryInterface | The metadata factory. |
