EOS 源代码解读 插件-插件模板

Posted 2022-02-21 thefist11

eos/plugins/template_plugin定义了eos项目中所有插件的模板

/**
 *  This is a template plugin, intended to serve as a starting point for making new plugins
 */
class template_plugin : public appbase::plugin<template_plugin> 
public:
   template_plugin();
   virtual ~template_plugin();
 
   APPBASE_PLUGIN_REQUIRES()
   virtual void set_program_options(options_description&, options_description& cfg) override;
 
   void plugin_initialize(const variables_map& options);
   void plugin_startup();
   void plugin_shutdown();

private:
   std::unique_ptr<class template_plugin_impl> my;
;

 static appbase::abstract_plugin& _template_plugin = app().register_plugin<template_plugin>();

class template_plugin_impl 
   public:
;

template_plugin::template_plugin():my(new template_plugin_impl())
template_plugin::~template_plugin()

void template_plugin::set_program_options(options_description&, options_description& cfg) 
   cfg.add_options()
         ("option-name", bpo::value<string>()->default_value("default value"),
          "Option Description")
         ;


void template_plugin::plugin_initialize(const variables_map& options) 
   try 
      if( options.count( "option-name" )) 
         // Handle the option
      
   
   FC_LOG_AND_RETHROW()


void template_plugin::plugin_startup() 
   // Make the magic happen


void template_plugin::plugin_shutdown() 
   // OK, that's enough magic
