Macro Definition Documentation

CLASS_LOADER_REGISTER_CLASS

#define CLASS_LOADER_REGISTER_CLASS	(		Derived,
			Base
	)		CLASS_LOADER_REGISTER_CLASS_WITH_MESSAGE(Derived, Base, "")

This is the macro which must be declared within the source (.cpp) file for each class that is to be exported as plugin. The macro utilizes a trick where a new struct is generated along with a declaration of static global variable of same type after it. The struct's constructor invokes a registration function with the plugin system. When the plugin system loads a library with registered classes in it, the initialization of static variables forces the invocation of the struct constructors, and all exported classes are automatically registerd.

CLASS_LOADER_REGISTER_CLASS_INTERNAL_HOP1_WITH_MESSAGE

#define CLASS_LOADER_REGISTER_CLASS_INTERNAL_HOP1_WITH_MESSAGE	(		Derived,
			Base,
			UniqueID,
			Message
	)		CLASS_LOADER_REGISTER_CLASS_INTERNAL_WITH_MESSAGE(Derived, Base, UniqueID, Message)

CLASS_LOADER_REGISTER_CLASS_INTERNAL_WITH_MESSAGE

#define CLASS_LOADER_REGISTER_CLASS_INTERNAL_WITH_MESSAGE	(		Derived,
			Base,
			UniqueID,
			Message
	)

Value:

namespace \
  { \
  struct ProxyExec ## UniqueID \
  { \
    typedef  Derived _derived; \
    typedef  Base _base; \
    ProxyExec ## UniqueID() \
    { \
      if (!std::string(Message).empty()) { \
        CONSOLE_BRIDGE_logInform("%s", Message);} \
      class_loader::impl::registerPlugin<_derived, _base>(#Derived, #Base); \
    } \
  }; \
  static ProxyExec ## UniqueID g_register_plugin_ ## UniqueID; \
  }

CLASS_LOADER_REGISTER_CLASS_WITH_MESSAGE

#define CLASS_LOADER_REGISTER_CLASS_WITH_MESSAGE	(		Derived,
			Base,
			Message
	)		CLASS_LOADER_REGISTER_CLASS_INTERNAL_HOP1_WITH_MESSAGE(Derived, Base, __COUNTER__, Message)

This macro is same as CLASS_LOADER_REGISTER_CLASS, but will spit out a message when the plugin is registered at library load time
