protected object|null extractObjectToPopulate(string $class, array $context, string $key = null)

Extract the object_to_populate field from the context if it exists and is an instance of the provided $class.

Parameters

string	$class	The class the object should be
array	$context	The denormalization context
string	$key	They in which to look for the object to populate. Keeps backwards compatibility with AbstractNormalizer.

Return Value

object|null

an object if things check out, null otherwise

setSerializer(SerializerInterface $serializer)

Sets the serializer.

Parameters

SerializerInterface

$serializer

A SerializerInterface instance

__construct(ClassMetadataFactoryInterface $classMetadataFactory = null, NameConverterInterface $nameConverter = null)

Sets the {@link ClassMetadataFactoryInterface} to use.

Parameters

ClassMetadataFactoryInterface	$classMetadataFactory
NameConverterInterface	$nameConverter

AbstractNormalizer setCircularReferenceLimit(int $circularReferenceLimit)

Set circular reference limit.

Parameters

int

$circularReferenceLimit

Limit of iterations for the same object

Return Value

AbstractNormalizer

AbstractNormalizer setCircularReferenceHandler(callable $circularReferenceHandler)

Set circular reference handler.

Parameters

callable

$circularReferenceHandler

Return Value

AbstractNormalizer

AbstractNormalizer setCallbacks(array $callbacks)

Set normalization callbacks.

Parameters

array

$callbacks

Help normalize the result

Return Value

AbstractNormalizer

Exceptions

InvalidArgumentException

if a non-callable callback is set

AbstractNormalizer setIgnoredAttributes(array $ignoredAttributes)

Set ignored attributes for normalization and denormalization.

Parameters

array

$ignoredAttributes

Return Value

AbstractNormalizer

bool hasCacheableSupportsMethod()

Return Value

bool

protected bool isCircularReference(object $object, array $context)

Detects if the configured circular reference limit is reached.

Parameters

object	$object
array	$context

Return Value

bool

Exceptions

CircularReferenceException

protected mixed handleCircularReference(object $object)

Handles a circular reference.

If a circular reference handler is set, it will be called. Otherwise, a {@class CircularReferenceException} will be thrown.

Parameters

object

$object

Return Value

mixed

Exceptions

CircularReferenceException

protected string[]|AttributeMetadataInterface[]|bool getAllowedAttributes(string|object $classOrObject, array $context, bool $attributesAsString = false)

Gets attributes to normalize using groups.

Parameters

string|object	$classOrObject
array	$context
bool	$attributesAsString	If false, return an array of {@link AttributeMetadataInterface}

Return Value

string[]|AttributeMetadataInterface[]|bool

Exceptions

LogicException

if the 'allow_extra_attributes' context variable is false and no class metadata factory is provided

protected bool isAllowedAttribute(object|string $classOrObject, string $attribute, string|null $format = null, array $context = array())

Is this attribute allowed?

Parameters

object|string	$classOrObject
string	$attribute
string|null	$format
array	$context

Return Value

bool

protected array prepareForDenormalization(object|array $data)

Normalizes the given data to an array. It's particularly useful during the denormalization process.

Parameters

object|array

$data

Return Value

array

protected ReflectionMethod|null getConstructor(array $data, string $class, array $context, ReflectionClass $reflectionClass, array|bool $allowedAttributes)

Returns the method to use to construct an object. This method must be either the object constructor or static.

Parameters

array	$data
string	$class
array	$context
ReflectionClass	$reflectionClass
array|bool	$allowedAttributes

Return Value

ReflectionMethod|null

protected object instantiateObject(array $data, string $class, array $context, ReflectionClass $reflectionClass, array|bool $allowedAttributes, string $format = null)

Instantiates an object using constructor parameters when needed.

This method also allows to denormalize data into an existing object if it is present in the context with the object_to_populate. This object is removed from the context before being returned to avoid side effects when recursively normalizing an object graph.

Parameters

array	$data
string	$class
array	$context
ReflectionClass	$reflectionClass
array|bool	$allowedAttributes
string	$format

Return Value

object

Exceptions

RuntimeException
MissingConstructorArgumentsException

protected array createChildContext(array $parentContext, string $attribute)

Parameters

array	$parentContext
string	$attribute

Return Value

array
