Google's Json Parsing Gson library: What's the difference between JsonElement and JsonObject?
android, gson, java
Solution
`JsonElement` contains common code for all the valid types in JSON:
- JsonObject
- JsonArray
- JsonPrimitive (string, number, boolean)
- JsonNull
This allows you a write a method that takes a `JsonElement` that works with any of the above types.
Problem
``` public abstract class JsonElement extends Object ``` A class representing an element of Json. It could either be a JsonObject, a JsonArray, a JsonPrimitive or a JsonNull. ``` public final class JsonObject extends JsonElement ``` A class representing an object type in Json. An object consists of name-value pairs where names are strings, and values are any other type of JsonElement. This allows for a creating a tree of JsonElements. The member elements of this object are maintained in order they were added. Yay google! Nevermind that question.
