Module: ShadowsocksRuby::Protocols::DummyHelper

Included in:
HttpSimpleProtocol, IvCipherProtocol, NoIvCipherProtocol, ShadowsocksProtocol, TlsTicketProtocol, VerifySha1Protocol
Defined in:
lib/shadowsocks_ruby/protocols/protocol.rb

Overview

This module include helper methods for a Packet/Cipher/Obfs Protocol.

To simplify boring long method name writing (eg: tcp_receive_from_client, tcp_send_to_client), two Adapter method are introduced and could be untilized: #async_recv and #send_data, they will be adapted to long method names (eg: tcp_receive_from_client, tcp_send_to_client) at runtime.

This helper module implement dummy #async_recv and #send_data, do nothing but just raise, in order to make things clear.

To use it, use include DummyHelper to include it into your protocol implementation.
