### Entry Point: Wiring the Decorator Chain

Source: https://gitlab.com/ocudu/ocudu_docs/-/blob/main/docs/dev_guide/architecture_guide/3_realization/8_plugins/3_decorator_chaining.md

Demonstrates how to build a processing chain by conditionally wrapping a base processor factory with a ZMQ decorator based on command-line arguments. This approach allows additive composition.

```cpp
std::shared_ptr<phy_tap_factory>
create_phy_tap_factory(unsigned nof_rb, unsigned nof_ports,
                       const std::string& args)
{
  // Start with the base processing stage.
  std::shared_ptr<external_ul_processor_factory> factory =
      std::make_shared<iq_tap_processor_factory>(nof_rb, nof_ports);

  // If tap_ul_epre=<address> appears in args, wrap with the ZMQ decorator.
  std::smatch m;
  if (std::regex_search(args, m, std::regex(R"(tap_ul_epre=([^,]*))" ))) {
    factory = std::make_shared<ul_epre_zmq_tap_factory>(std::move(factory), m[1].str());
  }
