SPAadm Class ADM_regobj_factory_mgr

ADM_regobj_factory_mgr

Usage: you must use this class as is. You should never derive it.

public class ADM_regobj_factory_mgr

Manages the singleton DM_regobj_factory providing global access to the unique instance.

Role: The ADM_regobj_factory_mgr is used by the ADM kernel as its access to the singleton ADM_regobj_factory. When the admgi_control library is initialized, it creates a concrete ADM_regobj_factory and loads it into the ADM_regobj_factory_mgr using the Replace_factory method. Users replacing the admgi_control library should do the same. If no concrete ADM_regobj_factory is loaded into the ADM_regobj_factory_mgr, the dmicon library will not draw.

Related classes: Access to a concrete ADM_regobjs is provided by the ADM_regobj_factory_mgr::Make_regobj method.
