Direct Known Subclasses:

DefaultSerializerProvider

public abstract class SerializerProvider
extends Object

Class that defines API used by ObjectMapper and JsonSerializers to obtain serializers capable of serializing instances of specific types; as well as the default implementation of the functionality.

Provider handles caching aspects of serializer handling; all construction details are delegated to SerializerFactory instance.

Object life-cycle is such that an initial instance ("blueprint") is created and referenced by ObjectMapper and ObjectWriter intances; but for actual usage, a configured instance is created by using a create method in sub-class DefaultSerializerProvider. Only this instance can be used for actual serialization calls; blueprint object is only to be used for creating instances.

                                           throws JsonMappingException

Method called to get hold of a serializer for a value of given type; or if no such serializer can be found, a default handler (which may do a best-effort generic serialization or just simply throw an exception when invoked).

Note: this method is only called for non-null values; not for keys or null values. For these, check out other accessor methods.

Note that starting with version 1.5, serializers should also be type-aware if they handle polymorphic types. That means that it may be necessary to also use a TypeSerializer based on declared (static) type being serializer (whereas actual data may be serialized using dynamic type)

Throws:

JsonMappingException - if there are fatal problems with accessing suitable serializer; including that of not finding any serializer

findValueSerializer

public JsonSerializer<Object> findValueSerializer(JavaType valueType,
                                                  BeanProperty property)
                                           throws JsonMappingException

Similar to findValueSerializer(Class,BeanProperty), but takes full generics-aware type instead of raw class. This is necessary for accurate handling of external type information, to handle polymorphic types.

Parameters:

property - When creating secondary serializers, property for which serializer is needed: annotations of the property (or bean that contains it) may be checked to create contextual serializers.

Throws:

JsonMappingException

findTypedValueSerializer

public JsonSerializer<Object> findTypedValueSerializer(Class<?> valueType,
                                                       boolean cache,
                                                       BeanProperty property)
                                                throws JsonMappingException

Method called to locate regular serializer, matching type serializer, and if both found, wrap them in a serializer that calls both in correct sequence. This method is currently only used for root-level serializer handling to allow for simpler caching. A call can always be replaced by equivalent calls to access serializer and type serializer separately.

Parameters:

valueType - Type for purpose of locating a serializer; usually dynamic runtime type, but can also be static declared type, depending on configuration

cache - Whether resulting value serializer should be cached or not; this is just a hint

property - When creating secondary serializers, property for which serializer is needed: annotations of the property (or bean that contains it) may be checked to create contextual serializers.

Throws:

JsonMappingException

findTypedValueSerializer

public JsonSerializer<Object> findTypedValueSerializer(JavaType valueType,
                                                       boolean cache,
                                                       BeanProperty property)
                                                throws JsonMappingException

Method called to locate regular serializer, matching type serializer, and if both found, wrap them in a serializer that calls both in correct sequence. This method is currently only used for root-level serializer handling to allow for simpler caching. A call can always be replaced by equivalent calls to access serializer and type serializer separately.

Parameters:

valueType - Declared type of value being serialized (which may not be actual runtime type); used for finding both value serializer and type serializer to use for adding polymorphic type (if any)

cache - Whether resulting value serializer should be cached or not; this is just a hint

property - When creating secondary serializers, property for which serializer is needed: annotations of the property (or bean that contains it) may be checked to create contextual serializers.

Throws:

JsonMappingException

findKeySerializer

public JsonSerializer<Object> findKeySerializer(JavaType keyType,
                                                BeanProperty property)
                                         throws JsonMappingException

Method called to get the serializer to use for serializing non-null Map keys. Separation from regular findValueSerializer(java.lang.Class, com.fasterxml.jackson.databind.BeanProperty) method is because actual write method must be different (@link JsonGenerator#writeFieldName}; but also since behavior for some key types may differ.

Note that the serializer itself can be called with instances of any Java object, but not nulls.

Throws:

JsonMappingException

getDefaultNullKeySerializer

public JsonSerializer<Object> getDefaultNullKeySerializer()

Since:

2.0

getDefaultNullValueSerializer

public JsonSerializer<Object> getDefaultNullValueSerializer()

Since:

2.0

findNullKeySerializer

public JsonSerializer<Object> findNullKeySerializer(JavaType serializationType,
                                                    BeanProperty property)
                                             throws JsonMappingException

Method called to find a serializer to use for null values for given declared type. Note that type is completely based on declared type, since nulls in Java have no type and thus runtime type can not be determined.

Throws:

JsonMappingException

Since:

2.0

findNullValueSerializer

public JsonSerializer<Object> findNullValueSerializer(BeanProperty property)
                                               throws JsonMappingException

Method called to get the serializer to use for serializing null property values.

Default implementation simply calls getDefaultNullValueSerializer(); can be overridden to add custom null serialization for properties of certain type or name.

Throws:

JsonMappingException

Since:

2.0

getUnknownTypeSerializer

public JsonSerializer<Object> getUnknownTypeSerializer(Class<?> unknownType)

Method called to get the serializer to use if provider can not determine an actual type-specific serializer to use; typically when none of SerializerFactory instances are able to construct a serializer.

Typically, returned serializer will throw an exception, although alternatively ToStringSerializer could be returned as well.

Parameters:

unknownType - Type for which no serializer is found

serializerInstance

public abstract JsonSerializer<Object> serializerInstance(Annotated annotated,
                                                          Object serDef)

Method that can be called to construct and configure serializer instance, either given a Class to instantiate (with default constructor), or an uninitialized serializer instance. Either way, serialize will be properly resolved (via ResolvableSerializer) and/or contextualized (via ContextualSerializer) as necessary.

Parameters:

annotated - Annotated entity that contained definition

serDef - Serializer definition: either an instance or class

Throws:

JsonMappingException
