All Implemented Interfaces:

TReadProtocol, TWriteProtocol
```
public class TSimpleJSONProtocol
extends TProtocol
```
JSON protocol implementation for thrift.
This protocol is write-only and produces a simple output format suitable for parsing by scripting languages. It should not be confused with the full-featured TJSONProtocol.
