null for root values.

Deprecated.
|

Value serializer to use, if it can be statically determined

---|
EnumMapSerializer(EnumMapSerializer src,
BeanProperty property,
JsonSerializer<?> ser)
Deprecated.
Constructor called when a contextual instance is created.

EnumMapSerializer(JavaType valueType,

Deprecated.
|
Modifier and Type | Method and Description |
---|---|
EnumMapSerializer |
_withValueTypeSerializer(TypeSerializer vts)
Deprecated.
Method that needs to be implemented to allow construction of a new
serializer object with given
TypeSerializer , used when
addition type information is to be embedded. |
void |
acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor,
JavaType typeHint)
Deprecated.
We consider possibility here that an EnumMap might actually just be serialized
as something like a Record, given that number of keys is bound, just like
with Objects/Records (and not unbounded like regular maps)
|
JsonSerializer<?> |
createContextual(SerializerProvider provider,
BeanProperty property)
Deprecated.
Method called to see if a different (or differently configured) serializer
is needed to serialize values of specified property.
|
JsonSerializer<?> |
getContentSerializer()
Deprecated.
Accessor for serializer used for serializing contents
(List and array elements, Map values etc) of the
container for which this serializer is used, if it is
known statically.
|
JavaType |
getContentType()
Deprecated.
Accessor for finding declared (static) element type for
type this serializer is used for.
|
JsonNode |
getSchema(SerializerProvider provider,
Type typeHint)
Deprecated.
Default implementation simply claims type is "string"; usually
overriden by custom serializers.
|
boolean |
hasSingleElement(EnumMap<? extends Enum<?>,?> value)
Deprecated.
Method called to determine if the given value (of type handled by
this serializer) contains exactly one element.
|
boolean |
isEmpty(SerializerProvider prov,
EnumMap<? extends Enum<?>,?> value)
Deprecated.
Method called to check whether given serializable value is
considered "empty" value (for purposes of suppressing serialization
of empty values).
|
void |
serialize(EnumMap<? extends Enum<?>,?> value,
com.fasterxml.jackson.core.JsonGenerator jgen,
SerializerProvider provider)
Deprecated.
Method that can be called to ask implementation to serialize
values of type this serializer handles.
|
protected void |
serializeContents(EnumMap<? extends Enum<?>,?> value,
com.fasterxml.jackson.core.JsonGenerator jgen,
SerializerProvider provider)
Deprecated.
|
protected void |

Deprecated.
|
void |
serializeWithType(EnumMap<? extends Enum<?>,?> value,
com.fasterxml.jackson.core.JsonGenerator jgen,
SerializerProvider provider,
TypeSerializer typeSer)
Deprecated.
Method that can be called to ask implementation to serialize
values of type this serializer handles, using specified type serializer
for embedding necessary type information.

JsonSerializer
Default implementation will throw UnsupportedOperationException
to indicate that proper type handling needs to be implemented.
For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like:
// note: method to call depends on whether this type is serialized as JSON scalar, object or Array! typeSer.writeTypePrefixForScalar(value, gen); serialize(value, gen, provider); typeSer.writeTypeSuffixForScalar(value, gen);and implementations for type serialized as JSON Arrays or Objects would differ slightly, as
START-ARRAY>/END-ARRAY
and
START-OBJECT>/END-OBJECT
pairs
need to be properly handled with respect to serializing of contents.
