Field Detail

instance

@Deprecated
public static final JsonNodeDeserializer instance
Deprecated. Use getDeserializer(java.lang.Class) accessor instead
Singleton instance of generic deserializer for JsonNode

Constructor Detail

JsonNodeDeserializer

protected JsonNodeDeserializer()
Method Detail

getDeserializer

public static JsonDeserializer<? extends JsonNode> getDeserializer(Class<?> nodeClass)
Factory method for accessing deserializer for specific node type


deserialize

public JsonNode deserialize(JsonParser jp,
                            DeserializationContext ctxt)
                     throws IOException,
                            JsonProcessingException
Implementation that will produce types of any JSON nodes; not just one deserializer is registered to handle (in case of more specialized handler). Overridden by typed sub-classes for more thorough checking

Specified by:
deserialize in class JsonDeserializer<JsonNode>
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

deserializeWithType

public Object deserializeWithType(JsonParser jp,
                                  DeserializationContext ctxt,
                                  TypeDeserializer typeDeserializer)
                           throws IOException,
                                  JsonProcessingException
Description copied from class: StdDeserializer
Base implementation that does not assume specific type inclusion mechanism. Sub-classes are expected to override this method if they are to handle type information.

Overrides:
deserializeWithType in class StdDeserializer<N extends JsonNode>
typeDeserializer - Deserializer to use for handling type information
Throws:
IOException
JsonProcessingException

_reportProblem

protected void _reportProblem(JsonParser jp,
                              String msg)
                       throws JsonMappingException
Throws:
JsonMappingException

_handleDuplicateField

protected void _handleDuplicateField(String fieldName,
                                     ObjectNode objectNode,
                                     JsonNode oldValue,
                                     JsonNode newValue)
                              throws JsonProcessingException
Method called when there is a duplicate value for a field. By default we don't care, and the last value is used. Can be overridden to provide alternate handling, such as throwing an exception, or choosing different strategy for combining values or choosing which one to keep.

Parameters:
fieldName - Name of the field for which duplicate value was found
objectNode - Object node that contains values
oldValue - Value that existed for the object node before newValue was added
newValue - Newly added value just added to the object node
Throws:
JsonProcessingException

deserializeObject

protected final ObjectNode deserializeObject(JsonParser jp,
                                             DeserializationContext ctxt)
                                      throws IOException,
                                             JsonProcessingException
Throws:
IOException
JsonProcessingException

deserializeArray

protected final ArrayNode deserializeArray(JsonParser jp,
                                           DeserializationContext ctxt)
                                    throws IOException,
                                           JsonProcessingException
Throws:
IOException
JsonProcessingException

deserializeAny

protected final JsonNode deserializeAny(JsonParser jp,
                                        DeserializationContext ctxt)
                                 throws IOException,
                                        JsonProcessingException
Throws:
IOException
JsonProcessingException
