Method Detail

serialize

public void serialize(Object value,
                      JsonGenerator gen,
                      SerializerProvider ctxt)
               throws IOException

Description copied from class: JsonSerializer

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

Overrides:

serialize in class ToEmptyObjectSerializer

Parameters:

value - Value to serialize; can not be null.

gen - Generator used to output resulting Json content

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

Throws:

IOException

serializeWithType

public void serializeWithType(Object value,
                              JsonGenerator gen,
                              SerializerProvider ctxt,
                              TypeSerializer typeSer)
                       throws IOException

Description copied from class: JsonSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

Default implementation will throw UnsupportedOperationException to indicate that proper type handling needs to be implemented.

For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like:

  // note: method to call depends on whether this type is serialized as JSON scalar, object or Array!
  typeSer.writeTypePrefixForScalar(value, gen);
  serialize(value, gen, provider);
  typeSer.writeTypeSuffixForScalar(value, gen);

and implementations for type serialized as JSON Arrays or Objects would differ slightly, as START-ARRAY/END-ARRAY and START-OBJECT/END-OBJECT pairs need to be properly handled with respect to serializing of contents.

Overrides:

serializeWithType in class ToEmptyObjectSerializer

Parameters:

value - Value to serialize; can not be null.

gen - Generator used to output resulting Json content

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

typeSer - Type serializer to use for including type information

Throws:

IOException

failForEmpty

protected void failForEmpty(SerializerProvider prov,
                            Object value)
                     throws JsonMappingException

Throws:

JsonMappingException
