Package com.arcadedb.serializer.json

Class JSONObject

java.lang.Object

com.arcadedb.serializer.json.JSONObject

public class JSONObject
extends Object

JSON object.
This API is compatible with org.json Java API, but uses Google GSON library under the hood. The main reason why we created this wrapper is because the maintainer of the project org.json are not open to support ordered attributes as an option.
