【EOSIO/appbase】

　　AppBase是EOSIO开源一个plugins架构程序框架，被应用于 EOS nodeos中。AppBase manages the plugin life-cycle and ensures that all plugins are configured, initialized, started, and shutdown in the proper order.

　　AppBase使用了 boost::program_options 库，以及 boost::asio 库。

class net_plugin : public appbase::plugin<net_plugin>
{
   public:
     net_plugin(){};
     ~net_plugin(){};

     APPBASE_PLUGIN_REQUIRES( (chain_plugin) );

     virtual void set_program_options( options_description& cli, options_description& cfg ) override
     {
        cfg.add_options()
              ("listen-endpoint", bpo::value<string>()->default_value( "127.0.0.1:9876" ), "The local IP address and port to listen for incoming connections.")
              ("remote-endpoint", bpo::value< vector<string> >()->composing(), "The IP address and port of a remote peer to sync with.")
              ("public-endpoint", bpo::value<string>()->default_value( "0.0.0.0:9876" ), "The public IP address and port that should be advertized to peers.")
              ;
     }

     void plugin_initialize( const variables_map& options ) { std::cout << "initialize net plugin\n"; }
     void plugin_startup()  { std::cout << "starting net plugin \n"; }
     void plugin_shutdown() { std::cout << "shutdown net plugin \n"; }

};
