classCModuleFactory{static CModuleFactory* instance();void addCreator(std::string type, CModuleCreator* pCreator);CControlHardware* create(std::string type, std::string name);};
This class provides a factory that allows the Module create slow control server command to instantiate driver objects from the name of the class. The factory operates by matching a driver type with a creator object. The creator object then instantiates the actual object.
Note that CModuleFactory is a
singleton. See instance
in METHODS below for information about how to get a
pointer to the singleton instance of this class,.
static CModuleFactory* instance();
Returns a pointer to the
singleton instance of this class. The class
constructor and destructor are
private to the class so this is the only
clean C++ mechanism to gain access to a
CModuleFactory object.
void addCreator(std::string type, CModuleCreator* pCreator);
Associates a new creator object with a module type.
type is the name of the
module type. When this type is used in a
Module create command,
the creator specified by pCreator
is used to generate the module object.
Note that the object pointed to by
pCreator must live for
the duration of the program.
CControlHardware* create(std::string type, std::string name);
Creates a specific type of
slow control driver named name.
The driver object is dynamically created. If it is necessary
to destroy it that must be done with delete.
