Class IdReferenceDeserializer

java.lang.Object

io.micronaut.serde.support.deserializers.IdReferenceDeserializer

All Implemented Interfaces:

Deserializer<Object>

@Internal
@Singleton
public final class IdReferenceDeserializer
extends Object
implements Deserializer<Object>

Deserializes a property that always references beans by their document-scoped identifier (JAXB @XmlIDREF, Jackson @JsonIdentityReference(alwaysAsId = true)): each identifier is resolved against the beans already read in the current document.

Since:

3.2

Constructor Details

IdReferenceDeserializer

@Inject
public IdReferenceDeserializer(SerdeIntrospections introspections)

Creates the unspecialized identifier-reference deserializer.

Parameters:

introspections - The serde introspections

Method Details

createSpecific

public Deserializer<Object> createSpecific(Deserializer.DecoderContext context,
 io.micronaut.core.type.Argument<? super Object> type)
                                    throws SerdeException

Description copied from interface: Deserializer

Create a new child deserializer or return this if non is necessary for the given context.

Specified by:

createSpecific in interface Deserializer<Object>

Parameters:

context - The decoder context

type - The context, including any annotation metadata and type information to narrow the deserializer type

Returns:

An instance of the same type of deserializer

Throws:

SerdeException

deserialize

public Object deserialize(Decoder decoder,
 Deserializer.DecoderContext context,
 io.micronaut.core.type.Argument<? super Object> type)
                   throws IOException

Description copied from interface: Deserializer

Deserializes from the current state of the Decoder an object of type T.

Specified by:

deserialize in interface Deserializer<Object>

Parameters:

decoder - The decoder, never null

context - The decoder context, never null

type - The generic type to be deserialized

Returns:

The deserialized object, never null. Use Deserializer.deserializeNullable(Decoder, DecoderContext, Argument) when the decoder value can be null.

Throws:

IOException - If an error occurs during deserialization of the object
