Fastjson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Fastjson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of.

### Fastjson Goals
 * Provide best performance in server side and android client
 * Provide simple toJSONString() and parseObject() methods to convert Java objects to JSON and vice-versa
 * Allow pre-existing unmodifiable objects to be converted to and from JSON
 * Extensive support of Java Generics
 * Allow custom representations for objects
 * Support arbitrarily complex objects (with deep inheritance hierarchies and extensive use of generic types)
