public class SimpleModule extends Module implements Serializable
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 AbstractTypeResolver
s,
ValueInstantiator
s).
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.

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,
com.fasterxml.jackson.core.Version version)
Constructor to use for actual reusable modules.
|
SimpleModule(String name,
com.fasterxml.jackson.core.Version version,
List<JsonSerializer<?>> serializers) |
SimpleModule(String name,
com.fasterxml.jackson.core.Version version,
Map<Class<?>,JsonDeserializer<?>> deserializers) |
SimpleModule(String name,
com.fasterxml.jackson.core.Version version,
Map<Class<?>,JsonDeserializer<?>> deserializers,
List<JsonSerializer<?>> serializers) |
SimpleModule(com.fasterxml.jackson.core.Version version)
Convenience constructor that will use specified Version,
including name from
Version.getArtifactId() |
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
|
com.fasterxml.jackson.core.Version |
version()
Method that returns version of this module.
