Constants
public Symfony\Component\Serializer\Normalizer\AbstractNormalizer::ALLOW_EXTRA_ATTRIBUTES = 'allow_extra_attributes'
 

If ATTRIBUTES are specified, and the source has fields that are not part of that list,
either ignore those attributes (true) or throw an ExtraAttributesException (false).

public Symfony\Component\Serializer\Normalizer\AbstractNormalizer::ATTRIBUTES = 'attributes'
 

Limit (de)normalize to the specified names.

For nested structures, this list needs to reflect the object tree.

public Symfony\Component\Serializer\Normalizer\AbstractNormalizer::CALLBACKS = 'callbacks'
 

Hashmap of field name => callable to (de)normalize this field.

The callable is called if the field is encountered with the arguments:

  • mixed $attributeValue value of this field
  • object|string $object the whole object being normalized or the object's class being denormalized
  • string $attributeName name of the attribute being (de)normalized
  • string $format the requested format
  • array $context the serialization context
public Symfony\Component\Serializer\Normalizer\AbstractNormalizer::CIRCULAR_REFERENCE_HANDLER = 'circular_reference_handler'
 

Handler to call when a circular reference has been detected.

If you specify no handler, a CircularReferenceException is thrown.

The method will be called with ($object, $format, $context) and its
return value is returned as the result of the normalize call.

public Symfony\Component\Serializer\Normalizer\AbstractNormalizer::CIRCULAR_REFERENCE_LIMIT = 'circular_reference_limit'
 

How many loops of circular reference to allow while normalizing.

The default value of 1 means that when we encounter the same object a
second time, we consider that a circular reference.

You can raise this value for special cases, e.g. in combination with the
max depth setting of the object normalizer.

public Symfony\Component\Serializer\Normalizer\DenormalizerInterface::COLLECT_DENORMALIZATION_ERRORS = 'collect_denormalization_errors'
public Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer::DEEP_OBJECT_TO_POPULATE = 'deep_object_to_populate'
 

Flag to tell the denormalizer to also populate existing objects on
attributes of the main object.

Setting this to true is only useful if you also specify the root object
in OBJECT_TO_POPULATE.

public Symfony\Component\Serializer\Normalizer\AbstractNormalizer::DEFAULT_CONSTRUCTOR_ARGUMENTS = 'default_constructor_arguments'
 

Hashmap of default values for constructor arguments.

The names need to match the parameter names in the constructor arguments.

public Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer::DEPTH_KEY_PATTERN = 'depth_%s::%s'
 

How to track the current depth in the context.

public Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer::DISABLE_TYPE_ENFORCEMENT = 'disable_type_enforcement'
 

While denormalizing, we can verify that types match.

You can disable this by setting this flag to true.

public Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer::ENABLE_MAX_DEPTH = 'enable_max_depth'
 

Set to true to respect the max depth metadata on fields.

public Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer::EXCLUDE_FROM_CACHE_KEY = 'exclude_from_cache_key'
 

Specify which context key are not relevant to determine which attributes
of an object to (de)normalize.

public Symfony\Component\Serializer\Normalizer\AbstractNormalizer::GROUPS = 'groups'
 

Only (de)normalize attributes that are in the specified groups.

public Symfony\Component\Serializer\Normalizer\AbstractNormalizer::IGNORED_ATTRIBUTES = 'ignored_attributes'
 

Skip the specified attributes when normalizing an object tree.

This list is applied to each element of nested structures.

Note: The behaviour for nested structures is different from ATTRIBUTES
for historical reason. Aligning the behaviour would be a BC break.

public Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer::MAX_DEPTH_HANDLER = 'max_depth_handler'
 

Callback to allow to set a value for an attribute when the max depth has
been reached.

If no callback is given, the attribute is skipped. If a callable is
given, its return value is used (even if null).

The arguments are:

  • mixed $attributeValue value of this field
  • object $object the whole object being normalized
  • string $attributeName name of the attribute being normalized
  • string $format the requested format
  • array $context the serialization context
public Symfony\Component\Serializer\Normalizer\AbstractNormalizer::OBJECT_TO_POPULATE = 'object_to_populate'
 

Instead of creating a new instance of an object, update the specified object.

If you have a nested structure, child objects will be overwritten with
new instances unless you set DEEP_OBJECT_TO_POPULATE to true.

public Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer::PRESERVE_EMPTY_OBJECTS = 'preserve_empty_objects'
 

Flag to control whether an empty object should be kept as an object (in
JSON: {}) or converted to a list (in JSON: []).

public Symfony\Component\Serializer\Normalizer\AbstractNormalizer::REQUIRE_ALL_PROPERTIES = 'require_all_properties'
 

Require all properties to be listed in the input instead of falling
back to null for nullable ones.

public Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer::SKIP_NULL_VALUES = 'skip_null_values'
 

Flag to control whether fields with the value null should be output
when normalizing or omitted.

public Symfony\Component\Serializer\Normalizer\AbstractObjectNormalizer::SKIP_UNINITIALIZED_VALUES = 'skip_uninitialized_values'
 

Flag to control whether uninitialized PHP>=7.4 typed class properties
should be excluded when normalizing.
