Class TypeSerializerWrapper

java.lang.Object

com.fasterxml.jackson.databind.jsontype.TypeSerializer

com.fasterxml.jackson.databind.jsontype.TypeSerializerWrapper

public class TypeSerializerWrapper
extends TypeSerializer

Helper class used in cases where we caller has to override source for type identifier, for example when serializing a value using a delegate or surrogate value, in which case type id is to be based on the original value, but serialization done using surrogate.

Methods

Modifier and Type	Method and Description
TypeSerializer	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.
TypeIdResolver	getTypeIdResolver() Accessor for object that handles conversions between types and matching type ids.

Method Detail

forProperty

public TypeSerializer 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).

Specified by:

forProperty in class TypeSerializer

getTypeInclusion

public 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.

Specified by:

getTypeInclusion in class TypeSerializer

getPropertyName

public String getPropertyName()

Description copied from class: TypeSerializer

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

Specified by:

getPropertyName in class TypeSerializer

getTypeIdResolver

public TypeIdResolver getTypeIdResolver()

Description copied from class: TypeSerializer

Accessor for object that handles conversions between types and matching type ids.

Specified by:

getTypeIdResolver in class TypeSerializer

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

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

writeTypeSuffixForScalar

public void writeTypeSuffixForScalar(Object value,

                                     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, com.fasterxml.jackson.core.JsonGenerator). Actual action to take may depend on various factors, but has to match with action TypeSerializer.writeTypePrefixForScalar(java.lang.Object, com.fasterxml.jackson.core.JsonGenerator) did (close array or object; or do nothing).

Specified by:

writeTypeSuffixForScalar in class TypeSerializer

Throws:

IOException

JsonProcessingException

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