Object mapper will convert Json content to ant from basic Java wrapper types (Integer, Boolean, Double), Collection types (List, Map), Java Beans, Strings and nulls.
Tree mapper builds dynamically typed tree of
from JSON content (and writes such trees as JSON),
similar to how DOM model works with XML.
Main benefits over Object mapping are:
JsonNodeclass, and when "incompatible" method (such as Array element access on, say, Boolean node) is used, returned node is virtual "missing" node.
