DEFINE_COMPONENT_FACTORY

#define DEFINE_COMPONENT_FACTORY	(		xFactoryType,
			xConfigType,
			xName,
			xDescription
	)

Value:

  class xFactoryType : public ::cloe::ComponentFactory {                                      \
   public:                                                                                    \
    xFactoryType() : ComponentFactory(xName, xDescription) {}                                 \
    std::unique_ptr<::cloe::ComponentFactory> clone() const override {                        \
      return std::make_unique<std::decay<decltype(*this)>::type>(*this);                      \
    }                                                                                         \
    std::unique_ptr<::cloe::Component> make(                                                  \
        const ::fable::Conf&, std::vector<std::shared_ptr<::cloe::Component>>) const override; \
                                                                                              \
   protected:                                                                                 \
    ::cloe::Schema schema_impl() override { return config_.schema(); }                        \
                                                                                              \
   private:                                                                                   \
    xConfigType config_;                                                                      \
  };

This macro defines a ComponentFactory named xFactoryType and with the configuration xConfigType. It should be used within the desired namespace.

The make method needs to be implemented:

std::unique_ptr<Component> xFactoryType::make(const Conf& c) {
  // implementation
}

The DEFINE_COMPONENT_FACTORY_MAKE macro can also be used to use the default implementation.

DEFINE_COMPONENT_FACTORY_MAKE

#define DEFINE_COMPONENT_FACTORY_MAKE	(		xFactoryType,
			xComponentType,
			xInputType
	)

Value:

  std::unique_ptr<::cloe::Component> xFactoryType::make(                                     \
      const ::fable::Conf& c, std::vector<std::shared_ptr<::cloe::Component>> comp) const {   \
    decltype(config_) conf{config_};                                                         \
    assert(comp.size() == 1);                                                                \
    if (!c->is_null()) {                                                                     \
      conf.from_conf(c);                                                                     \
    }                                                                                        \
    return std::make_unique<xComponentType>(                                                 \
        this->name(), conf, std::dynamic_pointer_cast<xInputType>(std::move(comp.front()))); \
  }

This macro defines the xFactoryType::make method for components with exactly one input component.

For this to work, the xComponentType must have a constructor with the following signature (see DEFINE_COMPONENT_FACTORY macro):

xComponentType(const std::string&, const xConfigType&, std::shared_ptr<xInputType>)
