#define DEFINE_VIRTUAL_LIBRARY

(

library_class_name

)

Value:

extern "C" { \
      virtual_library HOOPLE_DLL_EXPORT_FUNCTION *static_create_instance \
          (vl_data_pack &parameters) \
      { library_class_name blank; return blank.create_instance(parameters); } \
    }

this must be used in one and only one file in the virtual library's code.

it installs the instance creator into static scope; this is needed for our lookup process. the use of the macro is quite simple; if the root class of your virtual library is called SpongeCake, then the macro should be:

      DEFINE_VIRTUAL_LIBRARY(SpongeCake); 

the SpongeCake class must provide the virtual create_instance() function above in order to be a proper virtual_library. it must also have a blank constructor in order to work with this macro.

#define STATIC_CREATE_INSTANCE_NAME   "static_create_instance"

string form of the static method defined above in the macro.

this is provided so that we don't need to hard-code the name all over the place.
