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

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.serializeWithType in class JsonSerializer<Object>value - Value to serialize; can not be null.gen - Generator used to output resulting Json contentprovider - Provider that can be used to get serializers for
