public abstract class JsonSerializer<T>
extends Object

Abstract class that defines API used by ObjectMapper (and other chained JsonSerializers too) to serialize Objects of arbitrary types into JSON, using provided JsonGenerator.

Method Detail

serialize

public abstract void serialize(T value,
                               JsonGenerator jgen,
                               SerializerProvider provider)
                        throws IOException,
                               JsonProcessingException
Method that can be called to ask implementation to serialize values of type this serializer handles.

Parameters:
value - Value to serialize; can not be null.
jgen - Generator used to output resulting Json content
provider - Provider that can be used to get serializers for serializing Objects value contains, if any.
Throws:
IOException
JsonProcessingException

serializeWithType

public void serializeWithType(T value,
                              JsonGenerator jgen,
                              SerializerProvider provider,
                              TypeSerializer typeSer)
                       throws IOException,
                              JsonProcessingException
Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

Default implementation will ignore serialization of type information, and just calls serialize(T, org.codehaus.jackson.JsonGenerator, org.codehaus.jackson.map.SerializerProvider): serializers that can embed type information should override this to implement actual handling.

Parameters:
value - Value to serialize; can not be null.
jgen - Generator used to output resulting Json content
provider - Provider that can be used to get serializers for serializing Objects value contains, if any.
typeSer - Type serializer to use for including type information
Throws:
IOException
JsonProcessingException
Since:
1.5

handledType

public Class<T> handledType()
Method for accessing type of Objects this serializer can handle.

Default implementation will return null, which essentially means same as returning Object.class would; that is, that nothing is known about handled type.
