MetadataInterface getMetadataFor(mixed $value) Returns the metadata for the given value. Parameters mixed $value Some value Return Value MetadataInterface The metadata for the value Exceptions NoSuchMetadataException If no metadata exists for the given value

MetadataFactoryInterface getMetadataFactory() Returns the factory for metadata instances. Return Value MetadataFactoryInterface The metadata factory.

class Validator implements ValidatorInterface, MetadataFactoryInterface deprecated since version 2.5, to be removed in 3.0. Use {@link Validator\RecursiveValidator} instead. Default implementation of {@link ValidatorInterface}. Methods __construct(MetadataFactoryInterface $metadataFactory, ConstraintValidatorFactoryInterface $validatorFactory, TranslatorInterface $translator, $translationDomain = 'validators', array $objectInitializers = array()) MetadataFactoryInterface getMet

visit(MetadataInterface $metadata, mixed $value, string $group, string $propertyPath) Validates a value against the constraints defined in some metadata. This method implements the Visitor design pattern. See also {@link ValidationVisitorInterface}. Parameters 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.

validate(mixed $value, string $group, string $propertyPath, bool $traverse = false, bool $deep = false) 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 met

interface ValidationVisitorInterface deprecated since version 2.5, to be removed in 3.0. Validates values against constraints defined in {@link MetadataInterface} instances. This interface is an implementation of the Visitor design pattern. A value is validated by first passing it to the {@link validate} method. That method will determine the matching {@link MetadataInterface} for validating the value. It then calls the {@link MetadataInterface::accept} method of that metadata. accept()

This method implements the Visitor design pattern. See also {@link ValidationVisitorInterface}. Parameters 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.

If these elements can be collections again and you want to traverse them recursively, set the parameter $deep to true as well.

ValidationVisitorInterface getVisitor() Returns the visitor instance used to validate the object graph nodes. Return Value ValidationVisitorInterface The validation visitor.

ConstraintViolationListInterface getViolations() Returns the violations generated by the validator so far. Return Value ConstraintViolationListInterface A list of constraint violations.
