Class JsonReader

java.lang.Object

com.badlogic.gdx.utils.JsonReader

All Implemented Interfaces:

BaseJsonReader

public class JsonReader
extends Object
implements BaseJsonReader

Lightweight JSON parser.

The default behavior is to parse the JSON into a DOM containing JsonValue objects. Extend this class and override methods to perform event driven parsing. When this is done, the parse methods will return null.
