Detailed Description

template<typename T, typename U = RegistryTraits<T>>
class llvm::Registry< T, U >::listener

Abstract base class for registry listeners, which are informed when new entries are added to the registry. Simply subclass and instantiate:

   class CollectorPrinter : public Registry<Collector>::listener {
   protected:
     void registered(const Registry<Collector>::entry &e) {
       cerr << "collector now available: " << e->getName() << "\n";
     }

   public:
     CollectorPrinter() { init(); }  // Print those already registered.
   };

   CollectorPrinter Printer;
