---|---|---|
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,
com.fasterxml.jackson.core.JsonGenerator g,
SerializerProvider provider) |
Method that can be called to ask implementation to serialize
values of type this serializer handles.
|
void |
serializeWithType(byte[] value,
com.fasterxml.jackson.core.JsonGenerator g,
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 consider only null values to be empty.

public void serializeWithType(byte[] value, com.fasterxml.jackson.core.JsonGenerator g, SerializerProvider provider, TypeSerializer typeSer) throws IOException
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
