All Implemented Interfaces:
Closeable, AutoCloseable
public abstract class JSONReader extends Object implements Closeable
JSONReader is the core class for reading and parsing JSON data in FASTJSON2. It provides methods to read various data types from JSON including primitives, objects, arrays, dates, and custom types.

JSONReader supports multiple input sources including strings, byte arrays, streams, and readers. It also supports different character encodings such as UTF-8, UTF-16, and ASCII.

Example usage: 

 String json = "{\"name\":\"John\", \"age\":30}";
 try (JSONReader reader = JSONReader.of(json)) {
     JSONObject obj = reader.readObject();
     String name = (String) obj.get("name");
     Integer age = (Integer) obj.get("age");
 }
