 package com.fasterxml.jackson.databind;
Interface that can be implemented by objects that know how to serialize themselves to JSON, using com.fasterxml.jackson.core.JsonGenerator (and SerializerProvider 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: Jackson 2.0 added another method (from former "JsonSerializableWithType"), which is required for proper handling of case where additional type information is needed.

public interface JsonSerializable
Serialization method called when no additional type information is to be included in serialization.
    public void serialize(JsonGenerator jgenSerializerProvider provider)
        throws IOExceptionJsonProcessingException;

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 one of methods in com.fasterxml.jackson.databind.jsontype.TypeSerializer (such as com.fasterxml.jackson.databind.jsontype.TypeSerializer.writeTypePrefixForObject(java.lang.Object,com.fasterxml.jackson.core.JsonGenerator)) followed by serialization of contents, followed by another call to com.fasterxml.jackson.databind.jsontype.TypeSerializer (such as com.fasterxml.jackson.databind.jsontype.TypeSerializer.writeTypeSuffixForObject(java.lang.Object,com.fasterxml.jackson.core.JsonGenerator)). Exact methods to call in com.fasterxml.jackson.databind.jsontype.TypeSerializer 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.
