    Methods
    Modifier and Type | Method and Description
    --- | ---
    `protected void` | `failForEmpty(Object value)`
    `JsonNode` | `getSchema(SerializerProvider provider, Type typeHint)` Note: since Jackson 1.9, default implementation claims type is "string"
    `void` | `serialize(Object value, JsonGenerator jgen, SerializerProvider provider)` Method that can be called to ask implementation to serialize values of type this serializer handles.
    `void` | `serializeWithType(Object value, JsonGenerator jgen, SerializerProvider provider, TypeSerializer typeSer)` 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.

          public void serialize(Object value,
                       JsonGenerator jgen,
                       SerializerProvider provider)
                         throws IOException,
                                JsonMappingException

      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 `SerializerBase<Object>`
      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`
        `JsonMappingException`

    - #### serializeWithType

          public final void serializeWithType(Object value,
                               JsonGenerator jgen,
                               SerializerProvider provider,
                               TypeSerializer typeSer)
                                       throws IOException,
                                              JsonGenerationException

      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 ignore serialization of type information, and just calls `JsonSerializer.serialize(T, org.codehaus.jackson.JsonGenerator, org.codehaus.jackson.map.SerializerProvider)`: serializers that can embed type information should override this to implement actual handling. Most common such handling is done by something like:

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

      Overrides:
        `serializeWithType` in class `JsonSerializer<Object>`
      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.
        `typeSer` - Type serializer to use for including type information
      Throws:
        `IOException`
        `JsonGenerationException`

    - #### getSchema

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

      Description copied from class: `SerializerBase`
      Note: since Jackson 1.9, default implementation claims type is "string"
      Specified by:
        `getSchema` in interface `SchemaAware`
      Overrides:
        `getSchema` in class `SerializerBase<Object>`
      Parameters:
        `provider` - The serializer provider.
        `typeHint` - A hint about the type.
      Returns:
        Json-schema for this serializer.
      Throws:
        `JsonMappingException`

    - #### failForEmpty

          protected void failForEmpty(Object value)
                               throws JsonMappingException

      Throws:
        `JsonMappingException`
