The TAO_Singleton_Manager is basically simplified version of the ACE_Object_Manager. It is designed specifically to manage singletons created by TAO. For example, singleton instances created by TAO will be automatically registered with the singleton instance of this Singleton Manager.

Disallow copying by not implementing the following ...

Set a new unexpected exception handler.
The old one will be stored for restoration later on.
ACE_INLINE int TAO_Singleton_Manager::at_exit | ( | void * | object, | |
ACE_CLEANUP_FUNC | cleanup_hook, | |||
void * | param | |||
) | [static] |
cleanup_hook points to a (global, or static member) function that is called for the object or array when it to be destroyed. It may perform any necessary cleanup specific for that object or its class. param is passed as the second parameter to the cleanup_hook function; the first parameter is the object (or array) to be destroyed. cleanup_hook, for example, may delete the object (or array). For OS's that do not have processes, this function is the same as <at_thread_exit>. Returns 0 on success. On failure, returns -1 and sets errno to: EAGAIN if shutting down, ENOMEM if insufficient virtual memory, or EEXIST if the object (or array) had already been registered.
TAO_BEGIN_VERSIONED_NAMESPACE_DECL ACE_INLINE int TAO_Singleton_Manager::at_exit | ( | ACE_Cleanup * | object, | |
void * | param = 0 | |||
) | [static] |
The object is deleted via the ace_cleanup_destroyer. If you need more flexiblity, see the other at_exit method below. For OS's that do not have processes, cleanup takes place at the end of main. Returns 0 on success. On failure, returns -1 and sets errno to: EAGAIN if shutting down, ENOMEM if insufficient virtual memory, or EEXIST if the object (or array) had already been registered.
int TAO_Singleton_Manager::at_exit_i | ( | void * | object, | |
ACE_CLEANUP_FUNC | cleanup_hook, | |||
void * | param | |||
) | [private] |
Register an object or array for deletion at program termination. See description of static version above for return values.
sigset_t * TAO_Singleton_Manager::default_mask | ( | void | ) | [static] |
Accesses a default signal set used, for example, in ACE_Sig_Guard methods.
int TAO_Singleton_Manager::fini | ( | void | ) | [virtual] |
int TAO_Singleton_Manager::init | ( | int | register_with_object_manager | ) |
Explicitly initialize the TAO_Singleton_Manager, in addition to explicitly registering (or not registering) with the ACE_Object_Manager.
int TAO_Singleton_Manager::init | ( | void | ) | [virtual] |
TAO_Singleton_Manager * TAO_Singleton_Manager::instance | ( | void | ) | [static] |
Accessor to singleton instance.
TAO_Singleton_Manager& TAO_Singleton_Manager::operator= | ( | const TAO_Singleton_Manager & | ) | [private] |
Disallow copying by not implementing the following ...
int TAO_Singleton_Manager::shutting_down | ( | void | ) | [static] |
Returns 1 after the TAO_Singleton_Manager has been destroyed. See ACE_Object_Manager::shutting_down for more information.
int TAO_Singleton_Manager::starting_up | ( | void | ) | [static] |
Returns 1 before the TAO_Singleton_Manager has been constructed. See ACE_Object_Manager::starting_up for more information.
ACE_Thread_Hook * TAO_Singleton_Manager::thread_hook | ( | ACE_Thread_Hook * | new_thread_hook | ) | [static] |
Returns the existing thread hook and assign a new_thread_hook.
ACE_Thread_Hook * TAO_Singleton_Manager::thread_hook | ( | void | ) | [static] |
Returns the current thread hook for the process.
sigset_t* TAO_Singleton_Manager::default_mask_ [private] |
Default signal set used, for example, in ACE_Sig_Guard.
For at_exit support.
The old unexpected exception handler.
A pointer to the old unexpected exception handler is stored so that it can be restored when TAO is unloaded, for example. Otherwise, any unexpected exceptions will result in a call to TAO's unexpected exception handler which may no longer exist if TAO was unloaded.
int TAO_Singleton_Manager::registered_with_object_manager_ [private] |
Indicates if TAO_Singleton_Manager is registered with the ACE_Object_Manager.
Thread hook that's used by this process.
