public interface ClassMapper
extends ClassHelper

It is a ClassHelper which knows how to map the instances of a range of classes from JSON to Java and vice versa. The ClassMapper instances will be kept in a repository inside the JSONMapper, the mapper will locate the most specific ClassMapper and use this. If you want to create your own mapper for your class, you should implement this interface.

Map a Java instance to an instance of the JSON model.

Parameters:

mapper - The JSONMapper is passed as an argument for recursive mappings or to access the mapping options.

pojo - The Java instance that we want to convert the JSON model.
