Package org.apache.thrift.protocol

Class TSimpleJSONProtocol

java.lang.Object

org.apache.thrift.protocol.TProtocol

org.apache.thrift.protocol.TSimpleJSONProtocol

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.
