Symfony\Component\Validator\ValidatorInterface

interface ValidatorInterface

Validates values and graphs of objects and arrays.

ConstraintViolationListInterface	validate(mixed $value, array\|null $groups = null, bool $traverse = false, bool $deep = false) Validates a value.
ConstraintViolationListInterface	validateProperty(mixed $containingValue, string $property, array\|null $groups = null) Validates a property of a value against its current value.
ConstraintViolationListInterface	validatePropertyValue(mixed $containingValue, string $property, string $value, array\|null $groups = null) Validate a property of a value against a potential value.
ConstraintViolationListInterface	validateValue(mixed $value, Constraint\|Constraint[] $constraints, array\|null $groups = null) Validates a value against a constraint or a list of constraints.
MetadataFactoryInterface	getMetadataFactory() Returns the factory for metadata instances.

Validates a value.

The accepted values depend on the {@link MetadataFactoryInterface} implementation.

The signature changed with Symfony 2.5 (see {@link Validator\ValidatorInterface::validate()}. This signature will be disabled in Symfony 3.0.

mixed	$value	The value to validate
array\|null	$groups	The validation groups to validate.
bool	$traverse	Whether to traverse the value if it is traversable.
bool	$deep	Whether to traverse nested traversable values recursively.

A list of constraint violations. If the list is empty, validation succeeded.

Validates a property of a value against its current value.

The accepted values depend on the {@link MetadataFactoryInterface} implementation.

mixed	$containingValue	The value containing the property.
string	$property	The name of the property to validate.
array\|null	$groups	The validation groups to validate.

A list of constraint violations. If the list is empty, validation succeeded.

Validate a property of a value against a potential value.

The accepted values depend on the {@link MetadataFactoryInterface} implementation.

mixed	$containingValue	The value containing the property.
string	$property	The name of the property to validate
string	$value	The value to validate against the constraints of the property.
array\|null	$groups	The validation groups to validate.

A list of constraint violations. If the list is empty, validation succeeded.

Validates a value against a constraint or a list of constraints.

mixed	$value	The value to validate.
Constraint\|Constraint[]	$constraints	The constraint(s) to validate against.
array\|null	$groups	The validation groups to validate.

A list of constraint violations. If the list is empty, validation succeeded.

Returns the factory for metadata instances.

The metadata factory.
