Processing JSON with Jackson tree model APIs

The Jackson tree model API provides an in-memory representation of the JSON data. A client can optionally modify the object model representation. Here is a list of the core classes that you may need to know while dealing with tree model APIs in Jackson:

Class	Description
com.fasterxml.jackson.databind.ObjectMapper	This mapper class provides the functionality for converting between Java objects and matching JSON representations.
com.fasterxml.jackson.databind.JsonNode	This class is the base class for all JSON nodes, which form the basis of the JSON tree model in Jackson.
