public class EnumSerializer extends StdScalarSerializer<Enum<?>> implements ContextualSerializer
Enum types.
Based on StdScalarSerializer since the JSON value is
scalar (String).
JsonSerializer.None| Modifier and Type | Field and Description |
|---|---|
protected Boolean |
_serializeAsIndex
Flag that is set if we statically know serialization choice
between index and textual format (null if it needs to be dynamically
checked).
|
protected EnumValues |
_values
This map contains pre-resolved values (since there are ways
to customize actual String constants to use) to use as
serializations.

| Modifier and Type | Method and Description |
|---|---|
protected static Boolean |
_isShapeWrittenUsingIndex(Class<?> enumClass,
com.fasterxml.jackson.annotation.JsonFormat.Value format,
boolean fromClass,
Boolean defaultValue)
Helper method called to check whether serialization should be done using
index (number) or not.
|
protected boolean |
_serializeAsIndex(SerializerProvider serializers) |
void |
acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor,
JavaType typeHint)
Default implementation specifies no format.
|
static EnumSerializer |
construct(Class<?> enumClass,
SerializationConfig config,
BeanDescription beanDesc,
com.fasterxml.jackson.annotation.JsonFormat.Value format)
Factory method used by
BasicSerializerFactory
for constructing serializer instance of Enum types. |
JsonSerializer<?> |
createContextual(SerializerProvider serializers,
BeanProperty property)
To support some level of per-property configuration, we will need
to make things contextual.
|
EnumValues |
getEnumValues() |
JsonNode |
getSchema(SerializerProvider provider,
Type typeHint)
Default implementation simply claims type is "string"; usually
overriden by custom serializers.
|
void |
serialize(Enum<?> en,
com.fasterxml.jackson.core.JsonGenerator gen,
SerializerProvider serializers)
Method that can be called to ask implementation to serialize
values of type this serializer handles.
