ExecutionContext ^deprecated

__construct(GlobalExecutionContextInterface $globalContext, TranslatorInterface $translator, null|string $translationDomain = null, MetadataInterface $metadata = null, mixed $value = null, string $group = null, string $propertyPath = '')

Creates a new execution context.

Parameters

GlobalExecutionContextInterface	$globalContext	The global context storing node-independent state.
TranslatorInterface	$translator	The translator for translating violation messages.
null|string	$translationDomain	The domain of the validation messages.
MetadataInterface	$metadata	The metadata of the validated node.
mixed	$value	The value of the validated node.
string	$group	The current validation group.
string	$propertyPath	The property path to the current node.

addViolation(string $message, array $params = array(), mixed $invalidValue = null, int|null $plural = null, int|null $code = null)

Adds a violation at the current node of the validation graph.

Note: the parameters $invalidValue, $plural and $code are deprecated since version 2.5 and will be removed in 3.0.

Parameters

string	$message	The error message
array	$params	The parameters substituted in the error message
mixed	$invalidValue	The invalid, validated value
int|null	$plural	The number to use to pluralize of the message
int|null	$code	The violation code

addViolationAt(string $subPath, string $message, array $parameters = array(), mixed $invalidValue = null, int|null $plural = null, int|null $code = null)

Adds a violation at the validation graph node with the given property path relative to the current property path.

Parameters

string	$subPath	The relative property path for the violation
string	$message	The error message
array	$parameters	The parameters substituted in the error message
mixed	$invalidValue	The invalid, validated value
int|null	$plural	The number to use to pluralize of the message
int|null	$code	The violation code

ConstraintViolationListInterface getViolations()

Returns the violations generated by the validator so far.

Return Value

ConstraintViolationListInterface

The constraint violation list.

mixed getRoot()

Returns the value at which validation was started in the object graph.

The validator, when given an object, traverses the properties and related objects and their properties. The root of the validation is the object from which the traversal started.

The current value is returned by {@link getValue}.

Return Value

mixed

The root value of the validation.

string getPropertyPath(string $subPath = '')

Returns the property path to the value that the validator is currently validating.

For example, take the following object graph:

(Person)---($address: Address)---($street: string)

When the Person instance is passed to the validator, the property path is initially empty. When the $address property of that person is validated, the property path is "address". When the $street property of the related Address instance is validated, the property path is "address.street".

Properties of objects are prefixed with a dot in the property path. Indices of arrays or objects implementing the {@link \ArrayAccess} interface are enclosed in brackets. For example, if the property in the previous example is $addresses and contains an array of Address instance, the property path generated for the $street property of one of these addresses is for example "addresses[0].street".

Parameters

string

$subPath

Optional. The suffix appended to the current property path.

Return Value

string

The current property path. The result may be an empty string if the validator is currently validating the root value of the validation graph.

string|null getClassName()

Returns the class name of the current node.

If the metadata of the current node does not implement {@link ClassBasedInterface} or if no metadata is available for the current node, this method returns null.

Return Value

string|null

The class name or null, if no class name could be found.

string|null getPropertyName()

Returns the property name of the current node.

If the metadata of the current node does not implement {@link PropertyMetadataInterface} or if no metadata is available for the current node, this method returns null.

Return Value

string|null

The property name or null, if no property name could be found.

mixed getValue()

Returns the value that the validator is currently validating.

If you want to retrieve the object that was originally passed to the validator, use {@link getRoot}.

Return Value

mixed

The currently validated value.

string getGroup()

Returns the validation group that is currently being validated.

Return Value

string

The current validation group.

MetadataInterface|null getMetadata()

Returns the metadata for the currently validated value.

With the core implementation, this method returns a {@link Mapping\ClassMetadata} instance if the current value is an object, a {@link Mapping\PropertyMetadata} instance if the current value is the value of a property and a {@link Mapping\GetterMetadata} instance if the validated value is the result of a getter method.

If the validated value is neither of these, for example if the validator has been called with a plain value and constraint, this method returns null.

Return Value

MetadataInterface|null

The metadata of the currently validated value.

getMetadataFor($value)

{@inheritdoc}

Parameters

$value

validate(mixed $value, string $subPath = '', null|string|string[] $groups = null, bool $traverse = false, bool $deep = false)

Validates the given value within the scope of the current validation.

The value may be any value recognized by the used metadata factory (see {@link MetadataFactoryInterface::getMetadata}), or an array or a traversable object of such values.

Usually you validate a value that is not the current node of the execution context. For this case, you can pass the {@link $subPath} argument which is appended to the current property path when a violation is created. For example, take the following object graph:

(Person)---($address: Address)---($phoneNumber: PhoneNumber)
                    ^

When the execution context stops at the Person instance, the property path is "address". When you validate the PhoneNumber instance now, pass "phoneNumber" as sub path to correct the property path to "address.phoneNumber":

$context->validate($address->phoneNumber, 'phoneNumber');

Any violations generated during the validation will be added to the violation list that you can access with {@link getViolations}.

Parameters

mixed	$value	The value to validate.
string	$subPath	The path to append to the context's property path.
null|string|string[]	$groups	The groups to validate in. If you don't pass any groups here, the current group of the context will be used.
bool	$traverse	Whether to traverse the value if it is an array or an instance of \Traversable.
bool	$deep	Whether to traverse the value recursively if it is a collection of collections.

validateValue(mixed $value, Constraint|Constraint[] $constraints, string $subPath = '', null|string|string[] $groups = null)

Validates a value against a constraint.

Use the parameter $subPath to adapt the property path for the validated value. For example, take the following object graph:

(Person)---($address: Address)---($street: string)
                    ^

When the validator validates the Address instance, the property path stored in the execution context is "address". When you manually validate the property $street now, pass the sub path "street" to adapt the full property path to "address.street":

$context->validate($address->street, new NotNull(), 'street');

Parameters

mixed	$value	The value to validate.
Constraint|Constraint[]	$constraints	The constraint(s) to validate against.
string	$subPath	The path to append to the context's property path.
null|string|string[]	$groups	The groups to validate in. If you don't pass any groups here, the current group of the context will be used.

MetadataFactoryInterface getMetadataFactory()

Returns the used metadata factory.

Return Value

MetadataFactoryInterface

The metadata factory.
