Class JSONWrappedObject

java.lang.Object
  com.fasterxml.jackson.databind.util.JSONWrappedObject

All Implemented Interfaces:

JsonSerializable

public class JSONWrappedObject
extends Object
implements JsonSerializable

General-purpose wrapper class that can be used to decorate serialized value with arbitrary literal prefix and suffix. This can be used for example to construct arbitrary Javascript values (similar to how basic function name and parenthesis are used with JSONP).

Field Summary

protected String	_prefix Literal String to output before serialized value.
protected JavaType	_serializationType Optional static type to use for serialization; if null, runtime type is used.
protected String	_suffix Literal String to output after serialized value.
protected Object	_value Value to be serialized as JSONP padded; can be null.

Constructor Summary

JSONWrappedObject(String prefix, String suffix, Object value)

JSONWrappedObject(String prefix, String suffix, Object value, JavaType asType)
Constructor that should be used when specific serialization type to use is important, and needs to be passed instead of just using runtime (type-erased) type of the value.

Method Summary

String	getPrefix()
JavaType	getSerializationType()
String	getSuffix()
Object	getValue()
void	serialize(JsonGenerator jgen, SerializerProvider provider) Serialization method called when no additional type information is to be included in serialization.
void	serializeWithType(JsonGenerator jgen, SerializerProvider provider, TypeSerializer typeSer) Serialization method called when additional type information is expected to be included in serialization, for deserialization to use.

Field Detail

_prefix

protected final String _prefix

Literal String to output before serialized value. Will not be quoted when serializing value.

_suffix

protected final String _suffix

Literal String to output after serialized value. Will not be quoted when serializing value.

_value

protected final Object _value

Value to be serialized as JSONP padded; can be null.

_serializationType

protected final JavaType _serializationType

Optional static type to use for serialization; if null, runtime type is used. Can be used to specify declared type which defines serializer to use, as well as aspects of extra type information to include (if any).

Method Detail

serializeWithType

public void serializeWithType(JsonGenerator jgen,
                              SerializerProvider provider,
                              TypeSerializer typeSer)
                       throws IOException,
                              JsonProcessingException

Description copied from interface: JsonSerializable

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 TypeSerializer (such as TypeSerializer.writeTypePrefixForObject(Object, JsonGenerator)) followed by serialization of contents, followed by another call to TypeSerializer (such as TypeSerializer.writeTypeSuffixForObject(Object, JsonGenerator)). Exact methods to call in 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.
