Direct Known Subclasses:

CustomDeserializerFactory

public class BeanDeserializerFactory
extends BasicDeserializerFactory

Concrete deserializer factory class that adds full Bean deserializer construction logic using class introspection.

Since there is no caching, this factory is stateless and a globally shared singleton instance (instance) can be used by DeserializerProviders).

isPotentialBeanType

protected boolean isPotentialBeanType(java.lang.Class<?> type)

Helper method used to skip processing for types that we know can not be (i.e. are never consider to be) beans: things like primitives, Arrays, Enums, and proxy types.

Note that usually we shouldn't really be getting these sort of types anyway; but better safe than sorry.

Helper method that will check whether given raw type is marked as always ignorable (for purpose of ignoring properties with type)
