About

A component (interface implementation) can be added to a registry. The component is typically registered along its implementation (see Interface Implementation).

Registration

A given component can be registered at a registry using the MAXON_COMPONENT_CLASS_REGISTER macro. It is used to add the component to the registry and to define its ID:

// This example implements the given interface, registers
// the component and adds it to the given registry.
 
// implementation
 
class ColorRedImpl : public maxon::Component<ColorRedImpl, ColorInterface>
{
  MAXON_COMPONENT();
 
public:
  MAXON_METHOD maxon::String GetName() const
  {
    return "Red"_s;
  }
 
  MAXON_METHOD maxon::Color32 GetRGB() const
  {
    maxon::Color32 color;
    color.r = 1.0;
    color.g = 0.0;
    color.b = 0.0;
 
    return color;
  }
};
using namespace maxon;
 
// register component class and add it to registry "ColorClasses"
MAXON_COMPONENT_CLASS_REGISTER(ColorRedImpl, ColorClasses, "net.maxonexample.class.colors.red")
