A registry is used to share implementations of a certain interface. The declaration of the registry is typically found in the same header file that defines the interface.

Declaration

The declaration of a registry is placed between the two .hxx files generated for the given header file. The registry is defined using the MAXON_REGISTRY attribute. It defines:

The type of the exposed object. This is typically a maxon::Class referencing the interface using the reference class.
The class name of the registry. A static class with that name is used to access the registry.
The ID of the registry.

// This example shows a simple interface. Additionally a registry // is declared that will give access to implementations of this interface.

// --------------------------------------------------------------------- // Simple class to store a color. // --------------------------------------------------------------------- class ColorInterface : MAXON_INTERFACE_BASES (maxon::ObjectInterface) { MAXON_INTERFACE (ColorInterface, MAXON_REFERENCE_NORMAL , "net.maxonexample.interface.color" );

public : // --------------------------------------------------------------------- // Returns the name of the color. // --------------------------------------------------------------------- MAXON_METHOD maxon::String GetName() const ;

// --------------------------------------------------------------------- // Returns the RGB value of the color. // --------------------------------------------------------------------- MAXON_METHOD maxon::Color32 GetRGB() const ; };
