`ObjectMapper` | ObjectMapper.`enable(SerializationFeature first, SerializationFeature... f)` Method for enabling specified `DeserializationConfig` features.
`ObjectMapper` | ObjectMapper.`enableDefaultTyping()` Convenience method that is equivalent to calling

`ObjectMapper`

ObjectMapper.`enableDefaultTypingAsProperty(ObjectMapper.DefaultTyping applicability, String propertyName)`
Method for enabling automatic inclusion of type information -- needed for proper deserialization of polymorphic types (unless types have been annotated with `JsonTypeInfo`) -- using "As.PROPERTY" inclusion mechanism and specified property name to use for inclusion (default being "@class" since default type information always uses class name as type identifier)

`ObjectMapper` | ObjectMapper.`findAndRegisterModules()` Convenience method that is functionally equivalent to: `mapper.registerModules(mapper.findModules()); ```
`ObjectMapper` | MappingJsonFactory.`getCodec()` We'll override the method to return more specific type; co-variance helps here
`ObjectMapper` | ObjectMapper.`registerModule(Module module)` Method for registering a module that can extend functionality provided by this mapper; for example, by adding providers for custom serializers and deserializers.
`ObjectMapper` | ObjectMapper.`registerModules(Iterable<Module> modules)` Convenience method for registering specified modules in order; functionally equivalent to:
`ObjectMapper` | ObjectMapper.`registerModules(Module... modules)` Convenience method for registering specified modules in order; functionally equivalent to:
`ObjectMapper` | ObjectMapper.`setAnnotationIntrospector(AnnotationIntrospector ai)` Method for changing `AnnotationIntrospector` used by this mapper instance for both serialization and deserialization
`ObjectMapper` | ObjectMapper.`setAnnotationIntrospectors(AnnotationIntrospector serializerAI, AnnotationIntrospector deserializerAI)` Method for changing `AnnotationIntrospector` instances used by this mapper instance for serialization and deserialization, specifying them separately so that different introspection can be used for different aspects
`ObjectMapper` | ObjectMapper.`setBase64Variant(com.fasterxml.jackson.core.Base64Variant v)` Method that will configure default `Base64Variant` that `byte[]` serializers and deserializers will use.
`ObjectMapper` | ObjectMapper.`setConfig(DeserializationConfig config)` Method that allows overriding of the underlying `DeserializationConfig` object.
`ObjectMapper` | ObjectMapper.`setConfig(SerializationConfig config)` Method that allows overriding of the underlying `SerializationConfig` object, which contains serialization-specific configuration settings.

`ObjectMapper` | ObjectMapper.`setDefaultTyping(TypeResolverBuilder<?> typer)` Method for enabling automatic inclusion of type information, using specified handler object for determining which types this affects, as well as details of how information is embedded.
`ObjectMapper` | ObjectMapper.`setInjectableValues(InjectableValues injectableValues)` Method for configuring `InjectableValues` which used to find values to inject.
`ObjectMapper` | ObjectMapper.`setLocale(Locale l)` Method for overriding default locale to use for formatting.
`ObjectMapper` | ObjectMapper.`setNodeFactory(JsonNodeFactory f)` Method for specifying `JsonNodeFactory` to use for constructing root level tree nodes (via method `createObjectNode()`
`ObjectMapper` | ObjectMapper.`setPropertyNamingStrategy(PropertyNamingStrategy s)` Method for setting custom property naming strategy to use.
`ObjectMapper` | ObjectMapper.`setSerializationInclusion(com.fasterxml.jackson.annotation.JsonInclude.Include incl)` Method for setting defalt POJO property inclusion strategy for serialization.
