public class AsWrapperTypeSerializer
extends TypeSerializerBase

Type wrapper that tries to use an extra JSON Object, with a single entry that has type name as key, to serialize type information. If this is not possible (value is serialize as array or primitive), will use JsonTypeInfo.As#WRAPPER_ARRAY mechanism as fallback: that is, just use a wrapping array with type information as the first element and value as second.

Method Summary

JsonTypeInfo.As	getTypeInclusion() Accessor for type information inclusion method that serializer uses; indicates how type information is embedded in resulting JSON.
void	writeTypePrefixForArray(Object value, JsonGenerator jgen) Method called to write initial part of type information for given value, when it will be output as JSON Array value (not as JSON Object or scalar).
void	writeTypePrefixForObject(Object value, JsonGenerator jgen) Method called to write initial part of type information for given value, when it will be output as JSON Object value (not as JSON Array or scalar).

void	writeTypeSuffixForArray(Object value, JsonGenerator jgen)
void	writeTypeSuffixForObject(Object value, JsonGenerator jgen) Method called after value has been serialized, to close any scopes opened by earlier matching call to TypeSerializer.writeTypePrefixForObject(java.lang.Object, org.codehaus.jackson.JsonGenerator).

Accessor for type information inclusion method that serializer uses; indicates how type information is embedded in resulting JSON.

Specified by:

getTypeInclusion in class TypeSerializerBase

writeTypePrefixForObject

public void writeTypePrefixForObject(Object value,
                                     JsonGenerator jgen)
                              throws IOException,
                                     JsonProcessingException

Description copied from class: TypeSerializer

Method called to write initial part of type information for given value, when it will be output as JSON Object value (not as JSON Array or scalar). This means that context after call must be JSON Object, meaning that caller can then proceed to output field entries.

Specified by:

writeTypePrefixForObject in class TypeSerializer

Parameters:

value - Value that will be serialized, for which type information is to be written

jgen - Generator to use for writing type information

Throws:

IOException

JsonProcessingException

writeTypePrefixForArray

public void writeTypePrefixForArray(Object value,
                                    JsonGenerator jgen)
                             throws IOException,
                                    JsonProcessingException

Description copied from class: TypeSerializer

Method called to write initial part of type information for given value, when it will be output as JSON Array value (not as JSON Object or scalar). This means that context after call must be JSON Array, that is, there must be an open START_ARRAY to write contents in.

Specified by:

writeTypePrefixForArray in class TypeSerializer

Parameters:

value - Value that will be serialized, for which type information is to be written

jgen - Generator to use for writing type information

Throws:

IOException

JsonProcessingException

writeTypePrefixForScalar

public void writeTypePrefixForScalar(Object value,
                                     JsonGenerator jgen)
                              throws IOException,
                                     JsonProcessingException

Description copied from class: TypeSerializer

Method called to write initial part of type information for given value, when it will be output as scalar JSON value (not as JSON Object or Array). This means that the context after call can not be that of JSON Object; it may be Array or root context.

Specified by:

writeTypePrefixForScalar in class TypeSerializer

Parameters:

value - Value that will be serialized, for which type information is to be written

jgen - Generator to use for writing type information

Throws:

IOException

JsonProcessingException

writeTypeSuffixForObject

public void writeTypeSuffixForObject(Object value,
                                     JsonGenerator jgen)
                              throws IOException,
                                     JsonProcessingException

Description copied from class: TypeSerializer

Method called after value has been serialized, to close any scopes opened by earlier matching call to TypeSerializer.writeTypePrefixForObject(java.lang.Object, org.codehaus.jackson.JsonGenerator). It needs to write closing END_OBJECT marker, and any other decoration that needs to be matched.

Specified by:

writeTypeSuffixForObject in class TypeSerializer

Throws:

IOException

JsonProcessingException

writeTypeSuffixForArray

public void writeTypeSuffixForArray(Object value,
                                    JsonGenerator jgen)
                             throws IOException,
                                    JsonProcessingException

Specified by:

writeTypeSuffixForArray in class TypeSerializer

Throws:

IOException

JsonProcessingException

writeTypeSuffixForScalar

public void writeTypeSuffixForScalar(Object value,
                                     JsonGenerator jgen)
                              throws IOException,
                                     JsonProcessingException

Description copied from class: TypeSerializer

Method called after value has been serialized, to close any scopes opened by earlier matching call to TypeSerializer.writeTypePrefixForScalar(java.lang.Object, org.codehaus.jackson.JsonGenerator). It needs to write closing END_OBJECT marker, and any other decoration that needs to be matched.
