Method Summary

Methods

Modifier and Type	Method and Description
void	addAbstractTypeResolver(AbstractTypeResolver resolver) Method that module can use to register additional AbstractTypeResolver instance, to handle resolution of abstract to concrete types (either by defaulting, or by materializing).

void	addKeyDeserializers(KeyDeserializers s) Method that module can use to register additional deserializers to use for handling Map key values (which are separate from value deserializers because they are always serialized from String values)
void	addKeySerializers(Serializers s) Method that module can use to register additional serializers to use for handling Map key values (which are separate from value serializers because they must write JsonToken.FIELD_NAME instead of String value).

Method Detail

getMapperVersion

Version getMapperVersion()

Method that returns version information about ObjectMapper that implements this context. Modules can use this to choose different settings or initialization order; or even decide to fail set up completely if version is compatible with module.

getDeserializationConfig

DeserializationConfig getDeserializationConfig()

Method that returns current deserialization configuration settings. Since modules may be interested in these settings, caller should make sure to make changes to settings before module registrations.

getSerializationConfig

SerializationConfig getSerializationConfig()

Method that returns current serialization configuration settings. Since modules may be interested in these settings, caller should make sure to make changes to settings before module registrations.

addDeserializers

void addDeserializers(Deserializers d)

Method that module can use to register additional deserializers to use for handling types.

Parameters:

d - Object that can be called to find deserializer for types supported by module (null returned for non-supported types)

addKeyDeserializers

void addKeyDeserializers(KeyDeserializers s)

Method that module can use to register additional deserializers to use for handling Map key values (which are separate from value deserializers because they are always serialized from String values)

Since:

1.8

addSerializers

void addSerializers(Serializers s)

Method that module can use to register additional serializers to use for handling types.

Parameters:

s - Object that can be called to find serializer for types supported by module (null returned for non-supported types)

addKeySerializers

void addKeySerializers(Serializers s)

Method that module can use to register additional serializers to use for handling Map key values (which are separate from value serializers because they must write JsonToken.FIELD_NAME instead of String value).

Since:

1.8

addBeanDeserializerModifier

void addBeanDeserializerModifier(BeanDeserializerModifier mod)

Method that module can use to register additional modifier objects to customize configuration and construction of bean deserializers.

Parameters:

mod - Modifier to register

addBeanSerializerModifier

void addBeanSerializerModifier(BeanSerializerModifier mod)

Method that module can use to register additional modifier objects to customize configuration and construction of bean serializers.

Parameters:

mod - Modifier to register

addAbstractTypeResolver

void addAbstractTypeResolver(AbstractTypeResolver resolver)

Method that module can use to register additional AbstractTypeResolver instance, to handle resolution of abstract to concrete types (either by defaulting, or by materializing).

Parameters:

resolver - Resolver to add.

Since:

1.8

addTypeModifier

void addTypeModifier(TypeModifier modifier)

Method that module can use to register additional TypeModifier instance, which can augment JavaType instances constructed by TypeFactory.

Parameters:

modifier - to add

Since:

1.8

addValueInstantiators

void addValueInstantiators(ValueInstantiators instantiators)

Method that module can use to register additional ValueInstantiators, by adding ValueInstantiators object that gets called when instantatiator is needed by a deserializer.

Parameters:

instantiators - Object that can provide ValueInstantiators for constructing POJO values during deserialization

Since:

1.9

insertAnnotationIntrospector

void insertAnnotationIntrospector(AnnotationIntrospector ai)

Method for registering specified AnnotationIntrospector as the highest priority introspector (will be chained with existing introspector(s) which will be used as fallbacks for cases this introspector does not handle)

Parameters:

ai - Annotation introspector to register.

appendAnnotationIntrospector

void appendAnnotationIntrospector(AnnotationIntrospector ai)

Method for registering specified AnnotationIntrospector as the lowest priority introspector, chained with existing introspector(s) and called as fallback for cases not otherwise handled.

Parameters:

ai - Annotation introspector to register.

setMixInAnnotations

void setMixInAnnotations(Class<?> target,
                       Class<?> mixinSource)

Method used for defining mix-in annotations to use for augmenting specified class or interface. All annotations from mixinSource are taken to override annotations that target (or its supertypes) has.

Note: mix-ins are registered both for serialization and deserialization (which can be different internally).

Note: currently only one set of mix-in annotations can be defined for a single class; so if multiple modules register mix-ins, highest priority one (last one registered) will have priority over other modules.

Parameters:

target - Class (or interface) whose annotations to effectively override

mixinSource - Class (or interface) whose annotations are to be "added" to target's annotations, overriding as necessary
