## Member Typedef Documentation

typedef ACE_Hash_Map_Manager_Ex<ACE_CString, Components::ConsumerDescriptions_var, ACE_Hash<ACE_CString>, ACE_Equal_To<ACE_CString>, ACE_Null_Mutex> CIAO::NodeManager_Impl_Base::Component_Consumers_Map`[protected]`

typedef ACE_Hash_Map_Manager_Ex<ACE_CString, Components::FacetDescriptions_var, ACE_Hash<ACE_CString>, ACE_Equal_To<ACE_CString>, ACE_Null_Mutex> CIAO::NodeManager_Impl_Base::Component_Facets_Map`[protected]`

Cached object references of ports (facets/consumers) of all components. This is useful for getting the port object references of "shared components". The key in the map is the component instance name.

typedef struct CIAO::NodeManager_Impl_Base::_ref_count_info CIAO::NodeManager_Impl_Base::Ref_Count_Info

A struct that tracks the reference count of a particular component as well as the "child_plan_uuid" where the component is actually installed

typedef Reference_Count_Map::iterator CIAO::NodeManager_Impl_Base::Ref_Count_Iterator`[protected]`

typedef ACE_Hash_Map_Manager_Ex<ACE_CString, Ref_Count_Info, ACE_Hash<ACE_CString>, ACE_Equal_To<ACE_CString>, ACE_Null_Mutex> CIAO::NodeManager_Impl_Base::Reference_Count_Map`[protected]`

A reference count map for the components installed on this node @TODO We should also keep the information about *where* the component is installed

## Constructor & Destructor Documentation

CIAO::NodeManager_Impl_Base::NodeManager_Impl_Base | ( | const char * | name,
|  | CORBA::ORB_ptr | orb,
|  | PortableServer::POA_ptr | p,
|  | const char * | nodeapp_loc,
|  | const char * | nodeapp_options,
|  | int | spawn_delay |
| ) |  |  | throw (CORBA::SystemException)

Constructor.

CIAO::NodeManager_Impl_Base::~NodeManager_Impl_Base | ( | void |  | ) | `[protected, virtual]`

Since this class is reference counted, making this destructor protected to enforce proper memory managment through the reference counting mechanism (i.e. to disallow calling operator delete() on an instance of this class.
