SerializerBase

protected SerializerBase(Class<?> t,

Alternate constructor that is (alas!) needed to work around kinks of generic type handling

Method Detail

handledType

public final Class<T> handledType()

Description copied from class: JsonSerializer

Method for accessing type of Objects this serializer can handle. Note that this information is not guaranteed to be exact -- it may be a more generic (super-type) -- but it should not be incorrect (return a non-related type).

Default implementation will return null, which essentially means same as returning Object.class would; that is, that nothing is known about handled type.

Overrides:

handledType in class JsonSerializer<T>

serialize

public abstract void serialize(T value,
                               JsonGenerator jgen,
                               SerializerProvider provider)
                        throws IOException,
                               JsonGenerationException

Description copied from class: JsonSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles.

Specified by:

serialize in class JsonSerializer<T>

Parameters:

value - Value to serialize; can not be null.

jgen - Generator used to output resulting Json content

provider - Provider that can be used to get serializers for serializing Objects value contains, if any.

Throws:

IOException

JsonGenerationException

getSchema

public JsonNode getSchema(SerializerProvider provider,
                          Type typeHint)
                   throws JsonMappingException

Note: since Jackson 1.9, default implementation claims type is "string"

Specified by:

getSchema in interface SchemaAware

Parameters:

provider - The serializer provider.

typeHint - A hint about the type.

Returns:

Json-schema for this serializer.

Throws:

JsonMappingException

createObjectNode

protected ObjectNode createObjectNode()

createSchemaNode

protected ObjectNode createSchemaNode(String type)

createSchemaNode

protected ObjectNode createSchemaNode(String type,
                                      boolean isOptional)

isDefaultSerializer

protected boolean isDefaultSerializer(JsonSerializer<?> serializer)

Method that can be called to determine if given serializer is the default serializer Jackson uses; as opposed to a custom serializer installed by a module or calling application. Determination is done using JacksonStdImpl annotation on serializer class.

Since:

1.7

wrapAndThrow

public void wrapAndThrow(SerializerProvider provider,
                         Throwable t,
                         Object bean,
                         String fieldName)
                  throws IOException

Method that will modify caught exception (passed in as argument) as necessary to include reference information, and to ensure it is a subtype of IOException, or an unchecked exception.

Rules for wrapping and unwrapping are bit complicated; essentially:

• Errors are to be passed as is (if uncovered via unwrapping)
• "Plain" IOExceptions (ones that are not of type JsonMappingException are to be passed as is

Throws:

IOException

wrapAndThrow

public void wrapAndThrow(SerializerProvider provider,
                         Throwable t,
                         Object bean,
                         int index)
                  throws IOException

Throws:

IOException

                  throws IOException

Deprecated. Use version that takes SerializerProvider instead.

Throws:
