Class Inheritance
All Implemented Interfaces
com.badlogic.gdx.utils.BaseJsonReader
Imports
java.io.IOException, .InputStream, .InputStreamReader, .Reader, java.util.Arrays, com.badlogic.gdx.files.FileHandle, com.badlogic.gdx.utils.JsonValue.ValueType
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.
