instance which is stateless and fully thread-safe. |
ToStringSerializer(Class<?> handledType)
Sometimes it may actually make sense to retain actual handled type, so...

| 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,
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 g,
SerializerProvider provider,
TypeSerializer typeSer)
Default implementation will write type prefix, call regular serialization
method (since assumption is that value itself does not need JSON
Array or Object start/end markers), and then write type suffix.

public ToStringSerializer()
Note: usually you should NOT create new instances, but instead use
instance which is stateless and fully thread-safe. However,
there are cases where constructor is needed; for example,
when using explicit serializer annotations like
JsonSerialize.using().

public boolean isEmpty(SerializerProvider prov, Object value)
JsonSerializerDefault implementation will consider only null values to be empty.
NOTE: replaces JsonSerializer.isEmpty(Object), which was deprecated in 2.5
