public Interface JacksonSerializable

Known Direct Implementers
tools.jackson.databind.JacksonSerializable.Base, tools.jackson.databind.type.TypeBase, tools.jackson.databind.util.JSONPObject, tools.jackson.databind.util.JSONWrappedObject, tools.jackson.databind.util.RawValue
Imports
tools.jackson.core.*, tools.jackson.databind.jsontype.TypeSerializer
Interface that can be implemented by objects that know how to serialize themselves to JSON, using JsonGenerator (and SerializationContext if necessary).

Note that implementing this interface binds implementing object closely to Jackson API, and that it is often not necessary to do so -- if class is a bean, it can be serialized without implementing this interface.

Note that while it is possible to just directly implement JacksonSerializable, actual implementations are strongly recommended to instead extend JacksonSerializable.Base.

Note

in Jackson 2.x this type was named JsonSerializable

Nested and Inner Type Summary

Modifier and TypeClass and Description
public abstract static class
JacksonSerializable.Base

Base class with minimal implementation, as well as couple of extension methods that core Jackson databinding makes use of.

Method Summary

Modifier and TypeMethod and Description
public void
serialize(JsonGenerator gen, SerializationContext serializers)

Serialization method called when no additional type information is to be included in serialization.

public void
serializeWithType(JsonGenerator gen, SerializationContext serializers, TypeSerializer typeSer)

Serialization method called when additional type information is expected to be included in serialization, for deserialization to use.

Method Detail

serializeback to summary
public void serialize(JsonGenerator gen, SerializationContext serializers) throws JacksonException

Serialization method called when no additional type information is to be included in serialization.

serializeWithTypeback to summary
public void serializeWithType(JsonGenerator gen, SerializationContext serializers, TypeSerializer typeSer) throws JacksonException

Serialization method called when additional type information is expected to be included in serialization, for deserialization to use.

Usually implementation consists of a call to TypeSerializer#writeTypePrefix followed by serialization of contents, followed by a call to TypeSerializer#writeTypeSuffix). Details of the type id argument to pass depend on shape of JSON Object used (Array, Object or scalar like String/Number/Boolean).

Note that some types (most notably, "natural" types: String, Integer, Double and Boolean) never include type information.

All Implemented Interfaces
tools.jackson.databind.JacksonSerializable
Known Direct Subclasses
tools.jackson.databind.JsonNode, tools.jackson.databind.node.InternalNodeSerializer.WrapperForSerializer
Base class with minimal implementation, as well as couple of extension methods that core Jackson databinding makes use of. Use of this base class is strongly recommended over directly implementing JacksonSerializable.
