public class AsPropertyTypeSerializer
extends AsArrayTypeSerializer

Type serializer that preferably embeds type information as an additional JSON Object property, if possible (when resulting serialization would use JSON Object). If this is not possible (for JSON Arrays, scalars), uses a JSON Array wrapper (similar to how JsonTypeInfo.As.WRAPPER_ARRAY always works) as a fallback.

Methods

Modifier and Type	Method and Description
AsPropertyTypeSerializer	forProperty(BeanProperty prop) Method called to create contextual version, to be used for values of given property.
String	getPropertyName() Name of property that contains type information, if property-based inclusion is used.
com.fasterxml.jackson.annotation.JsonTypeInfo.As	getTypeInclusion() Accessor for type information inclusion method that serializer uses; indicates how type information is embedded in resulting JSON.
void	writeCustomTypePrefixForObject(Object value, com.fasterxml.jackson.core.JsonGenerator jgen, String typeId) 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), using specified custom type id instead of calling TypeIdResolver.
void	writeCustomTypeSuffixForObject(Object value, com.fasterxml.jackson.core.JsonGenerator jgen, String typeId)
void	writeTypePrefixForObject(Object value, com.fasterxml.jackson.core.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	writeTypePrefixForObject(Object value, com.fasterxml.jackson.core.JsonGenerator jgen, Class<?> type) Alternative version of the prefix-for-object method, which is given actual type to use (instead of using exact type of the value); typically a super type of actual value type
void	writeTypeSuffixForObject(Object value, com.fasterxml.jackson.core.JsonGenerator jgen) Method called after value has been serialized, to close any scopes opened by earlier matching call to TypeSerializer.writeTypePrefixForObject(java.lang.Object, com.fasterxml.jackson.core.JsonGenerator).

AsPropertyTypeSerializer

public AsPropertyTypeSerializer(TypeIdResolver idRes,
                        BeanProperty property,
                        String propName)

Method Detail

forProperty

public AsPropertyTypeSerializer forProperty(BeanProperty prop)

Description copied from class: TypeSerializer

Method called to create contextual version, to be used for values of given property. This may be the type itself (as is the case for bean properties), or values contained (for Collection or Map valued properties).

Overrides:

forProperty in class AsArrayTypeSerializer

getPropertyName

public String getPropertyName()

Description copied from class: TypeSerializer

Name of property that contains type information, if property-based inclusion is used.

Overrides:

getPropertyName in class TypeSerializerBase

getTypeInclusion

public com.fasterxml.jackson.annotation.JsonTypeInfo.As getTypeInclusion()

Description copied from class: TypeSerializer

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

Overrides:

getTypeInclusion in class AsArrayTypeSerializer

writeTypePrefixForObject

public void writeTypePrefixForObject(Object value,
                            com.fasterxml.jackson.core.JsonGenerator jgen)
                              throws IOException

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.

Overrides:

writeTypePrefixForObject in class AsArrayTypeSerializer

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

writeTypePrefixForObject

public void writeTypePrefixForObject(Object value,
                            com.fasterxml.jackson.core.JsonGenerator jgen,
                            Class<?> type)
                              throws IOException

Description copied from class: TypeSerializer

Alternative version of the prefix-for-object method, which is given actual type to use (instead of using exact type of the value); typically a super type of actual value type

Overrides:

writeTypePrefixForObject in class AsArrayTypeSerializer

Throws:

IOException

writeTypeSuffixForObject

public void writeTypeSuffixForObject(Object value,
                            com.fasterxml.jackson.core.JsonGenerator jgen)
                              throws IOException

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, com.fasterxml.jackson.core.JsonGenerator). It needs to write closing END_OBJECT marker, and any other decoration that needs to be matched.

Overrides:

writeTypeSuffixForObject in class AsArrayTypeSerializer

Throws:

IOException

writeCustomTypePrefixForObject

public void writeCustomTypePrefixForObject(Object value,
                                  com.fasterxml.jackson.core.JsonGenerator jgen,
                                  String typeId)
                                    throws IOException

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), using specified custom type id instead of calling TypeIdResolver. This means that context after call must be JSON Object, meaning that caller can then proceed to output field entries.

Overrides:

writeCustomTypePrefixForObject in class AsArrayTypeSerializer

Parameters:

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

jgen - Generator to use for writing type information

typeId - Exact type id to use

Throws:

IOException

writeCustomTypeSuffixForObject

public void writeCustomTypeSuffixForObject(Object value,
                                  com.fasterxml.jackson.core.JsonGenerator jgen,
                                  String typeId)
                                    throws IOException

Overrides:

writeCustomTypeSuffixForObject in class AsArrayTypeSerializer

Throws:

IOException
