SimpleModule (jackson-databind 2.7.1-1)

java.lang.Object
- com.fasterxml.jackson.databind.Module
- - com.fasterxml.jackson.databind.module.SimpleModule

All Implemented Interfaces:

Versioned, Serializable
```
public class SimpleModule
extends Module
implements Serializable
```
Vanilla Module implementation that allows registration of serializers and deserializers, bean serializer and deserializer modifiers, registration of subtypes and mix-ins as well as some other commonly needed aspects (addition of custom AbstractTypeResolvers, ValueInstantiators).
NOTE: although it is not expected that sub-types should need to override Module.setupModule(SetupContext) method, if they choose to do so they MUST call super.setupModule(context); to ensure that registration works as expected.

Constructors
Constructor and Description
`SimpleModule()` Constructors that should only be used for non-reusable convenience modules used by app code: "real" modules should use actual name and version number information.
`SimpleModule(String name)` Convenience constructor that will default version to `Version.unknownVersion()`.
`SimpleModule(String name, Version version)` Constructor to use for actual reusable modules.
`SimpleModule(String name, Version version, List<JsonSerializer<?>> serializers)`
`SimpleModule(String name, Version version, Map<Class<?>,JsonDeserializer<?>> deserializers)`
`SimpleModule(String name, Version version, Map<Class<?>,JsonDeserializer<?>> deserializers, List<JsonSerializer<?>> serializers)`

Method Summary

Methods
Modifier and Type	Method and Description
`<T> SimpleModule`	`addAbstractTypeMapping(Class<T> superType, Class<? extends T> subType)` Lazily-constructed resolver used for storing mappings from abstract classes to more specific implementing classes (which may be abstract or concrete)
`<T> SimpleModule`	`addDeserializer(Class<T> type, JsonDeserializer<? extends T> deser)`
`SimpleModule`	`addKeyDeserializer(Class<?> type, KeyDeserializer deser)`
`<T> SimpleModule`	`addKeySerializer(Class<? extends T> type, JsonSerializer<T> ser)`
`<T> SimpleModule`	`addSerializer(Class<? extends T> type, JsonSerializer<T> ser)`
`SimpleModule`	`addSerializer(JsonSerializer<?> ser)`
`SimpleModule`	`addValueInstantiator(Class<?> beanType, ValueInstantiator inst)` Method for registering `ValueInstantiator` to use when deserializing instances of type `beanType`.
`String`	`getModuleName()` Method that returns a display that can be used by Jackson for informational purposes, as well as in associating extensions with module that provides them.
`Object`	`getTypeId()` Since instances are likely to be custom, implementation returns `null` if (but only if!) this class is directly instantiated; but class name (default impl) for sub-classes.
`SimpleModule`	`registerSubtypes(Class<?>... subtypes)` Method for adding set of subtypes to be registered with `ObjectMapper` this is an alternative to using annotations in super type to indicate subtypes.
`SimpleModule`	`registerSubtypes(NamedType... subtypes)` Method for adding set of subtypes (along with type name to use) to be registered with `ObjectMapper` this is an alternative to using annotations in super type to indicate subtypes.
`void`	`setAbstractTypes(SimpleAbstractTypeResolver atr)` Resets currently configured abstract type mappings
`SimpleModule`	`setDeserializerModifier(BeanDeserializerModifier mod)`
`void`	`setDeserializers(SimpleDeserializers d)` Resets all currently configured deserializers.
`void`	`setKeyDeserializers(SimpleKeyDeserializers kd)` Resets all currently configured key deserializers.
`void`	`setKeySerializers(SimpleSerializers ks)` Resets all currently configured key serializers.
`SimpleModule`	`setMixInAnnotation(Class<?> targetType, Class<?> mixinClass)` Method for specifying that annotations define by `mixinClass` should be "mixed in" with annotations that `targetType` has (as if they were directly included on it!).
`protected SimpleModule`	`setNamingStrategy(PropertyNamingStrategy naming)`
`SimpleModule`	`setSerializerModifier(BeanSerializerModifier mod)`
`void`	`setSerializers(SimpleSerializers s)` Resets all currently configured serializers.
`void`	`setupModule(Module.SetupContext context)` Standard implementation handles registration of all configured customizations: it is important that sub-classes call this implementation (usually before additional custom logic) if they choose to override it; otherwise customizations will not be registered.
`void`	`setValueInstantiators(SimpleValueInstantiators svi)` Resets all currently configured value instantiators
`Version`	`version()` Method that returns version of this module.
