## Class EnumMapSerializer

- java.lang.Object
- - org.codehaus.jackson.map.JsonSerializer<T>
  - - org.codehaus.jackson.map.ser.std.SerializerBase<T>
    - - org.codehaus.jackson.map.ser.std.ContainerSerializerBase<EnumMap<? extends Enum<?>,?>>
      - - org.codehaus.jackson.map.ser.std.EnumMapSerializer

- All Implemented Interfaces:
    ResolvableSerializer, SchemaAware

      public class EnumMapSerializer
      extends ContainerSerializerBase<EnumMap<? extends Enum<?>,?>>
      implements ResolvableSerializer

  Specialized serializer for `EnumMap`s. Somewhat tricky to implement because actual Enum value type may not be available; and if not, it can only be gotten from actual instance.

    - #### serialize

          public void serialize(EnumMap<? extends Enum<?>,?> value,
                       JsonGenerator jgen,

                         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 `SerializerBase<EnumMap<? extends Enum<?>,?>>`
      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.

    - #### serializeWithType

          public void serializeWithType(EnumMap<? extends Enum<?>,?> value,
                               JsonGenerator jgen,

                                        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<EnumMap<? extends Enum<?>,?>>`
      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`

    - #### serializeContents

          protected void serializeContents(EnumMap<? extends Enum<?>,?> value,
                               JsonGenerator jgen,
                               SerializerProvider provider)
                                    throws IOException,
                                           JsonGenerationException

    - #### resolve

          public void resolve(SerializerProvider provider)
                       throws JsonMappingException

      Description copied from interface: `ResolvableSerializer`
      Method called after `SerializerProvider` has registered the serializer, but before it has returned it to the caller. Called object can then resolve its dependencies to other types, including self-references (direct or indirect).

        `resolve` in interface `ResolvableSerializer`
      Parameters:
        `provider` - Provider that has constructed serializer this method is called on.

      Description copied from class: `SerializerBase`

      Overrides:
        `getSchema` in class `SerializerBase<EnumMap<? extends Enum<?>,?>>`
      Parameters:
        `provider` - The serializer provider.
        `typeHint` - A hint about the type.
      Returns:
        Json-schema for this serializer.
      Throws:
        `JsonMappingException`
