All Implemented Interfaces:

JsonFormatVisitable, SchemaAware, ContextualSerializer, Serializable

public class EnumSerializer
extends StdScalarSerializer<Enum<?>>
implements ContextualSerializer

Standard serializer used for Enum types.

Based on StdScalarSerializer since the JSON value is scalar (String).

protected final 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 final EnumValues	_values	This map contains pre-resolved values (since there are ways to customize actual String constants to use) to use as serializations.

Field Details

_values

protected final EnumValues _values

This map contains pre-resolved values (since there are ways to customize actual String constants to use) to use as serializations.

_serializeAsIndex

protected final 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).

Since:

2.1

Constructor Details

EnumSerializer

public EnumSerializer(EnumValues v,
 Boolean serializeAsIndex)

Method Details

construct

public static EnumSerializer construct(Class<?> enumClass,
 SerializationConfig config,
 BeanDescription beanDesc,
 JsonFormat.Value format)

Factory method used by BasicSerializerFactory for constructing serializer instance of Enum types.

Since:

2.1

createContextual

public JsonSerializer<?> createContextual(SerializerProvider serializers,
 BeanProperty property)
                                   throws JsonMappingException

To support some level of per-property configuration, we will need to make things contextual. We are limited to "textual vs index" choice here, however.

Specified by:

createContextual in interface ContextualSerializer

Parameters:

serializers - Serializer provider to use for accessing config, other serializers

property - Method or field that represents the property (and is used to access value to serialize). Should be available; but there may be cases where caller cannot provide it and null is passed instead (in which case impls usually pass 'this' serializer as is)

Returns:

Serializer to use for serializing values of specified property; may be this instance or a new instance.

Throws:

JsonMappingException

getEnumValues

public EnumValues getEnumValues()

serialize

public final void serialize(Enum<?> en,
 JsonGenerator gen,
 SerializerProvider serializers)
                     throws IOException

Description copied from class: JsonSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles.

Specified by:

serialize in class StdSerializer<Enum<?>>

Parameters:

en - Value to serialize; can not be null.

gen - Generator used to output resulting Json content

serializers - Provider that can be used to get serializers for serializing Objects value contains, if any.

Throws:

IOException

getSchema

public JsonNode getSchema(SerializerProvider provider,
 Type typeHint)

Description copied from class: StdSerializer

Default implementation simply claims type is "string"; usually overriden by custom serializers.

Specified by:

getSchema in interface SchemaAware

Overrides:

getSchema in class StdScalarSerializer<Enum<?>>

Parameters:

provider - The serializer provider.

typeHint - A hint about the type.

Returns:

Json-schema for this serializer.

acceptJsonFormatVisitor

public void acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor,
 JavaType typeHint)
                             throws JsonMappingException

Description copied from class: StdSerializer

Default implementation specifies no format. This behavior is usually overriden by custom serializers.

Specified by:

acceptJsonFormatVisitor in interface JsonFormatVisitable

Overrides:

acceptJsonFormatVisitor in class StdScalarSerializer<Enum<?>>

typeHint - Type of element (entity like property) being visited

Throws:

JsonMappingException

_serializeAsIndex

protected final boolean _serializeAsIndex(SerializerProvider serializers)

_isShapeWrittenUsingIndex

protected static Boolean _isShapeWrittenUsingIndex(Class<?> enumClass,
 JsonFormat.Value format,
 boolean fromClass,
 Boolean defaultValue)

Helper method called to check whether serialization should be done using index (number) or not.
