Class BeanSerializerFactory
- All Implemented Interfaces:
Serializable
Object.getClass()
does not count);
as well as for "standard" JDK types. Latter is achieved
by delegating calls to BasicSerializerFactory
to find serializers both for "standard" JDK types (and in some cases,
sub-classes as is the case for collection classes like
List
s and Map
s) and bean (value)
classes.
Note about delegating calls to BasicSerializerFactory
:
although it would be nicer to use linear delegation
for construction (to essentially dispatch all calls first to the
underlying BasicSerializerFactory
; or alternatively after
failing to provide bean-based serializer}, there is a problem:
priority levels for detecting standard types are mixed. That is,
we want to check if a type is a bean after some of "standard" JDK
types, but before the rest.
As a result, "mixed" delegation used, and calls are NOT done using
regular SerializerFactory
interface but rather via
direct calls to BasicSerializerFactory
.
Finally, since all caching is handled by the serializer provider (not factory) and there is no configurability, this factory is stateless. This means that a global singleton instance can be used.

createSerializer
public JsonSerializer<Object> createSerializer(SerializerProvider prov, JavaType origType) throws JsonMappingException Main serializer constructor method. We will have to be careful with respect to ordering of various method calls: essentially we want to reliably figure out which classes are standard types, and which are beans. The problem is that some bean Classes may implement standard interfaces (say,Iterable
.Note: sub-classes may choose to complete replace implementation, if they want to alter priority of serializer lookups.
