-     public final class ObjectIdWriter
      extends Object

  Object that knows how to serialize Object Ids.

- - ### Field Summary

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `boolean` | `alwaysAsId` Marker that indicates what the first reference is to be serialized as full POJO, or as Object Id (other references will always be serialized as Object Id)
    `ObjectIdGenerator<?>` | `generator` Blueprint generator instance: actual instance will be fetched from `SerializerProvider` using this as the key.
    `JavaType` | `idType`
    `SerializableString` | `propertyName` Name of id property to write, if not null: if null, should only write references, but id property is handled by some other entity.
    `JsonSerializer<Object>` | `serializer` Serializer used for serializing id values.

    `static ObjectIdWriter` | `construct(JavaType idType, PropertyName propName, ObjectIdGenerator<?> generator, boolean alwaysAsId)` Factory method called by `BeanSerializerBase` with the initial information based on standard settings for the type for which serializer is being built.
    `static ObjectIdWriter` | `construct(JavaType idType, String propName, ObjectIdGenerator<?> generator, boolean alwaysAsId)` Deprecated.
    `ObjectIdWriter` | `withAlwaysAsId(boolean newState)`
