diff src/common/Module.cpp @ 1117:3c6206da8bcf
Add Module::registerInstance() and Module::getInstance().
Module::registerInstance() registers a module instance which can later
be retrieved using Module::getInstance().
registerInstance() is called in luax_register_module().
getInstance() expects the full name (as returned by Module::getName())
of the requested module.
