Class JsonValueSerializer

      org.codehaus.jackson.map.ser.JsonValueSerializer

All Implemented Interfaces:

ResolvableSerializer

public final class JsonValueSerializer
extends JsonSerializer<java.lang.Object>
implements ResolvableSerializer

Serializer class that can serialize Object that have a JsonValue annotation to indicate that serialization should be done by calling the method annotated, and serializing result it returns.

Implementation note: we will post-process resulting serializer (much like what is done with BeanSerializer) to figure out actual serializers for final types. This must be done from resolve(org.codehaus.jackson.map.SerializerProvider) method, and NOT from constructor; otherwise we could end up with an infinite loop.

Constructor Summary

JsonValueSerializer(java.lang.reflect.Method valueMethod, JsonSerializer<java.lang.Object> ser)

Method Summary

void	resolve(SerializerProvider provider) We can try to find the actual serializer for value, if we can statically figure out what the result type must be.
void	serialize(java.lang.Object bean, JsonGenerator jgen, SerializerProvider prov) Method that can be called to ask implementation to serialize values of type this serializer handles.
java.lang.String	toString()

Constructor Detail

JsonValueSerializer

public JsonValueSerializer(java.lang.reflect.Method valueMethod,
                           JsonSerializer<java.lang.Object> ser)

Parameters:

ser - Explicit serializer to use, if caller knows it (which occurs if and only if the "value method" was annotated with JsonUseSerializer), otherwise null

Method Detail

serialize

public void serialize(java.lang.Object bean,
                      JsonGenerator jgen,
                      SerializerProvider prov)
               throws java.io.IOException,
                      JsonGenerationException

Description copied from class: JsonSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles.

Specified by:

serialize in class JsonSerializer<java.lang.Object>

Parameters:

bean - Value to serialize; can not be null.

jgen - Generator used to output resulting Json content

prov - Provider that can be used to get serializers for serializing Objects value contains, if any.

Throws:

java.io.IOException

JsonGenerationException

resolve

public void resolve(SerializerProvider provider)
             throws JsonMappingException

We can try to find the actual serializer for value, if we can statically figure out what the result type must be.

Specified by:

resolve in interface ResolvableSerializer

Parameters:

provider - Provider that has constructed serializer this method is called on.

Throws:

JsonMappingException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
