public abstract class AnnotationIntrospector extends Object implements Versioned, Serializable
Although default implementations are based on using annotations as the only (or at least main) information source, custom implementations are not limited in such a way, and in fact there is no expectation they should be. So the name is bit of misnomer; this is a general configuration introspection facility.
NOTE: due to rapid addition of new methods (and changes to existing methods),
it is strongly recommended that custom implementations should not directly
extend this class, but rather extend NopAnnotationIntrospector
.
This way added methods will not break backwards compatibility of custom annotation
introspectors.

Converter
that annotated entity
(property or class) has indicated to be used as part of
deserialization.
If not null, either has to be actual
Converter
instance, or class for such converter;
and resulting converter will be used after Jackson has deserializer
data into intermediate type (Converter input type), and Converter
needs to convert this into its target type to be set as property value.
This feature is typically used to convert intermediate Jackson types (that default deserializers can produce) into custom type instances.
Note also that this feature does not necessarily work well with polymorphic type handling, or object identity handling; if such features are needed an explicit deserializer is usually better way to handle deserialization.
