Class ObjectMapper

java.lang.Object

com.facebook.stetho.json.ObjectMapper

public class ObjectMapper
extends java.lang.Object

This class is a lightweight version of Jackson's ObjectMapper. It is designed to have a minimal subset of the functionality required for stetho.

It would be awesome if there were a lightweight library that supported converting between arbitrary Object and JSONObject representations.

Admittedly the other approach would be to use an Annotation Processor to create static conversion functions that discover something like a JsonProperty and create a function at compile time however since this is just being used for a simple debug utility and Kit-Kat caches the results of reflection this class is sufficient for stethos needs.
