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;
