public class ByteArraySerializer extends StdSerializer<byte[]>
NOTE: since it is NOT serialized as an array, can not use AsArraySerializer as base
NOTE: since 2.6, has been a main-level class; earlier was embedded in
StdArraySerializers.

| Modifier and Type | Method and Description |
|---|---|
void |
acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor,
JavaType typeHint)
Default implementation specifies no format.
|
JsonNode |
getSchema(SerializerProvider provider,
Type typeHint)
Default implementation simply claims type is "string"; usually
overriden by custom serializers.
|
boolean |
isEmpty(SerializerProvider prov,
byte[] value)
Method called to check whether given serializable value is
considered "empty" value (for purposes of suppressing serialization
of empty values).
|
void |
serialize(byte[] value,
JsonGenerator jgen,
SerializerProvider provider)
Method that can be called to ask implementation to serialize
values of type this serializer handles.
|
void |
serializeWithType(byte[] value,
JsonGenerator jgen,
SerializerProvider provider,
TypeSerializer typeSer)
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.

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
