Detailed Description

Interface to allow generic factories for replicas to register themselves. Factories are distinguished by the role to be played by the created-object (role) and the location at which they create the object (FactoryInfo.the_location)

Because this is an extension to the FT CORBA specification applications that wish to adhere to the specification as written should use the type id as the role name when interacting with the FactoryRegistry.

Member Function Documentation

FactoryInfos PortableGroup::FactoryRegistry::list_factories_by_location (  in Location    location )

List all the factories that create a objects at a given location. If no factories are registered for this location, an empty list is returned. This is not an error. Parameters: location  where the factories create objects.

FactoryInfos PortableGroup::FactoryRegistry::list_factories_by_role (  in RoleName    role, out _TypeId    type_id )

List all the factories that create objects that fill a given role If the role is unknown, an empty list is returned. This is not an error. Parameters: role  the type of object the factories create. type_id  what type of object is created to fill this role.

void PortableGroup::FactoryRegistry::register_factory (  in RoleName    role, in _TypeId    type_id, in FactoryInfo    factory_info )  raises (MemberAlreadyPresent, TypeConflict)

register a factory to create objects of the given type at the location given in the FactoryInfo. Parameters: role  the role the object-to-be-created plays. type_id  type id of the object-to-be-created. factory_info  information about the factory including its location. Exceptions: MemberAlreadyPresent  if there is already a factory for this type of object at this location. TypeConflict  if the specified type_id is different from the type_id previously registered for this role.

void PortableGroup::FactoryRegistry::unregister_factory (  in RoleName    role, in Location    location )  raises (MemberNotFound)

Remove the registration of a factory. Parameters: role  the role played by the object formerly created by this factory. location  where the factory formerly created objects. Exceptions: MemberNotPresent  if no factory is available for the given role at this location.

void PortableGroup::FactoryRegistry::unregister_factory_by_location (  in Location    location )

Remove the registration of all factories that create objects at a particular location. If the location is unknown the registry is unchanged. This is not an error. Parameters: location  where the factories formerly created objects.

void PortableGroup::FactoryRegistry::unregister_factory_by_role (  in RoleName    role )

Remove the registration of all factories that create a particular type of object. If no factories exist for the given type, the registry is unchanged. This is not an error. Parameters: type_id  the type of object formerly created by the factories to be unregistered.
