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

array|string|int|float|bool normalize(mixed $object, string $format = null, array $context = array())

Normalizes an object into a set of arrays/scalars.

Parameters

mixed	$object	Object to normalize
string	$format	Format the normalization result will be encoded as
array	$context	Context options for the normalizer

Return Value

array|string|int|float|bool

Exceptions

InvalidArgumentException	Occurs when the object given is not an attempted type for the normalizer
CircularReferenceException	Occurs when the normalizer detects a circular reference when no circular reference handler can fix it
LogicException	Occurs when the normalizer is not called in an expected context

object denormalize(mixed $data, string $class, string $format = null, array $context = array())

Denormalizes data back into an object of the given class.

Parameters

mixed	$data	Data to restore
string	$class	The expected class to instantiate
string	$format	Format the given data was extracted from
array	$context	Options available to the denormalizer

Return Value

object

Exceptions

BadMethodCallException	Occurs when the normalizer is not called in an expected context
InvalidArgumentException	Occurs when the arguments are not coherent or not supported
UnexpectedValueException	Occurs when the item cannot be hydrated with the given data
ExtraAttributesException	Occurs when the item doesn't have attribute to receive given data
LogicException	Occurs when the normalizer is not supposed to denormalize
RuntimeException	Occurs if the class cannot be instantiated

bool supportsNormalization(mixed $data, string $format = null)

Checks if the given class implements the NormalizableInterface.

Parameters

mixed	$data	Data to normalize
string	$format	The format being (de-)serialized from or into

Return Value

bool

bool supportsDenormalization(mixed $data, string $type, string $format = null)

Checks if the given class implements the DenormalizableInterface.

Parameters

mixed	$data	Data to denormalize from
string	$type	The class to which the data should be denormalized
string	$format	The format being deserialized from

Return Value

bool

bool hasCacheableSupportsMethod()

Return Value

bool
