public class AsExternalTypeSerializer extends TypeSerializerBase
AsPropertyTypeSerializer
.
Note that implementation of serialization is bit cumbersome as we must serialized external type id AFTER object; this because callback only occurs after field name has been written.

getPropertyName()
Name of property that contains type information, if
property-based inclusion is used.
|
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 |
writeTypePrefixForArray(Object value,
JsonGenerator jgen,
Class<?> type)
Alternative version of the prefix-for-array 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 |
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).

writeTypePrefixForObject(Object value,
JsonGenerator jgen,
Class<?> type)

|
void |
writeTypePrefixForScalar(Object value,
JsonGenerator jgen)
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).

writeTypePrefixForScalar(Object value,
JsonGenerator jgen,

|
void |
writeTypeSuffixForArray(Object value,

Method called after value has been serialized, to close any scopes opened
by earlier matching call to
