Constructor Detail

BeanAsArrayBuilderDeserializer

public BeanAsArrayBuilderDeserializer(BeanDeserializerBase delegate,
                              SettableBeanProperty[] ordered,
                              AnnotatedMethod buildMethod)

Main constructor used both for creating new instances (by BeanDeserializer.asArrayDeserializer()) and for creating copies with different delegate.

Method Detail

unwrappingDeserializer

public JsonDeserializer<Object> unwrappingDeserializer(NameTransformer unwrapper)

Description copied from class: JsonDeserializer

Method that will return deserializer instance that is able to handle "unwrapped" value instances If no unwrapped instance can be constructed, will simply return this object as-is.

Default implementation just returns 'this' indicating that no unwrapped variant exists

Specified by:

unwrappingDeserializer in class BeanDeserializerBase

withObjectIdReader

public BeanAsArrayBuilderDeserializer withObjectIdReader(ObjectIdReader oir)

Specified by:

withObjectIdReader in class BeanDeserializerBase

withIgnorableProperties

public BeanAsArrayBuilderDeserializer withIgnorableProperties(HashSet<String> ignorableProps)

Specified by:

withIgnorableProperties in class BeanDeserializerBase

asArrayDeserializer

protected BeanAsArrayBuilderDeserializer asArrayDeserializer()

Description copied from class: BeanDeserializerBase

Fluent factory for creating a variant that can handle POJO output as a JSON Array. Implementations may ignore this request if no such input is possible.

Specified by:

asArrayDeserializer in class BeanDeserializerBase

finishBuild

protected final Object finishBuild(DeserializationContext ctxt,
                 Object builder)
                            throws IOException

Throws:

IOException

deserialize

public Object deserialize(JsonParser jp,
                 DeserializationContext ctxt)
                   throws IOException,
                          JsonProcessingException

Description copied from class: JsonDeserializer

Method that can be called to ask implementation to deserialize JSON content into the value type this serializer handles. Returned instance is to be constructed by method itself.

Pre-condition for this method is that the parser points to the first event that is part of value to deserializer (and which is never JSON 'null' literal, more on this below): for simple types it may be the only value; and for structured types the Object start marker. Post-condition is that the parser will point to the last event that is part of deserialized value (or in case deserialization fails, event that was not recognized or usable, which may be the same event as the one it pointed to upon call).

Note that this method is never called for JSON null literal, and thus deserializers need (and should) not check for it.

Specified by:

deserialize in class JsonDeserializer<Object>

Parameters:

jp - Parsed used for reading JSON content

ctxt - Context that can be used to access information about this deserialization activity.

Returns:

Deserializer value

Throws:

IOException

JsonProcessingException

deserialize

public Object deserialize(JsonParser jp,
                 DeserializationContext ctxt,
                 Object builder)
                   throws IOException,
                          JsonProcessingException

Description copied from class: JsonDeserializer

Alternate deserialization method (compared to the most commonly used, JsonDeserializer.deserialize(JsonParser, DeserializationContext)), which takes in initialized value instance, to be configured and/or populated by deserializer. Method is not necessarily used for all supported types; most commonly it is used for Collections and Maps.

Default implementation just throws UnsupportedOperationException, to indicate that types that do not explicitly add support do not necessarily support update-existing-value operation (esp. immutable types)

Overrides:

deserialize in class JsonDeserializer<Object>

Throws:

IOException

JsonProcessingException

deserializeFromObject

public Object deserializeFromObject(JsonParser jp,
                           DeserializationContext ctxt)
                             throws IOException,
                                    JsonProcessingException

Description copied from class: BeanDeserializerBase

General version used when handling needs more advanced features.

Specified by:

deserializeFromObject in class BeanDeserializerBase

Throws:

IOException

JsonProcessingException

_deserializeNonVanilla

protected Object _deserializeNonVanilla(JsonParser jp,
                            DeserializationContext ctxt)
                                 throws IOException,
                                        JsonProcessingException

Alternate deserialization method that has to check many more configuration aspects than the "vanilla" processing. Note: should NOT resolve builder; caller will do that

Returns:

Builder object in use.

Throws:

IOException

JsonProcessingException

_deserializeWithCreator

protected Object _deserializeWithCreator(JsonParser jp,
                             DeserializationContext ctxt)
                                  throws IOException,
                                         JsonProcessingException

Throws:

IOException

JsonProcessingException

_deserializeUsingPropertyBased

protected final Object _deserializeUsingPropertyBased(JsonParser jp,
                                    DeserializationContext ctxt)
                                               throws IOException,
                                                      JsonProcessingException

Method called to deserialize bean using "property-based creator": this means that a non-default constructor or factory method is called, and then possibly other setters. The trick is that values for creator method need to be buffered, first; and due to non-guaranteed ordering possibly some other properties as well.

Specified by:

_deserializeUsingPropertyBased in class BeanDeserializerBase

Throws:

IOException

JsonProcessingException

_deserializeFromNonArray

protected Object _deserializeFromNonArray(JsonParser jp,
                              DeserializationContext ctxt)
                                   throws IOException,
                                          JsonProcessingException

Throws:

IOException

JsonProcessingException
