abstract class AbstractNormalizer implements NormalizerInterface, DenormalizerInterface, SerializerAwareInterface, CacheableSupportsMethodInterface

Normalizer implementation.

Traits

ObjectToPopulateTrait
SerializerAwareTrait SerializerAware trait.

Constants

CIRCULAR_REFERENCE_LIMIT
OBJECT_TO_POPULATE
GROUPS
ATTRIBUTES
ALLOW_EXTRA_ATTRIBUTES
DEFAULT_CONSTRUCTOR_ARGUMENTS

Properties

protected SerializerInterface $serializer from SerializerAwareTrait
protected int $circularReferenceLimit
protected callable $circularReferenceHandler
protected ClassMetadataFactoryInterface|null $classMetadataFactory
protected NameConverterInterface|null $nameConverter
protected array $callbacks
protected array $ignoredAttributes
protected array $camelizedAttributes

Methods

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.

from ObjectToPopulateTrait
setSerializer(SerializerInterface $serializer)

Sets the serializer.

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

Sets the {@link ClassMetadataFactoryInterface} to use.

AbstractNormalizer setCircularReferenceLimit(int $circularReferenceLimit)

Set circular reference limit.

AbstractNormalizer setCircularReferenceHandler(callable $circularReferenceHandler)

Set circular reference handler.

AbstractNormalizer setCallbacks(array $callbacks)

Set normalization callbacks.

AbstractNormalizer setIgnoredAttributes(array $ignoredAttributes)

Set ignored attributes for normalization and denormalization.

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

Detects if the configured circular reference limit is reached.

mixed handleCircularReference(object $object)

Handles a circular reference.

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

Gets attributes to normalize using groups.

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

Is this attribute allowed?

array prepareForDenormalization(object|array $data)

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

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.

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

Instantiates an object using constructor parameters when needed.

array createChildContext(array $parentContext, string $attribute)

Details

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
