Destructor.
| void TAO_ESF_Copy_On_Write< PROXY, COLLECTION, ITERATOR, ACE_SYNCH_DECL >::connected | ( | PROXY * | proxy | ) | [virtual] |
Insert a new element into the collection. The collection assumes ownership of the element.
Implements TAO_ESF_Proxy_Collection< PROXY >.
| void TAO_ESF_Copy_On_Write< PROXY, COLLECTION, ITERATOR, ACE_SYNCH_DECL >::disconnected | ( | PROXY * | proxy | ) | [virtual] |
Remove an element from the collection.
Implements TAO_ESF_Proxy_Collection< PROXY >.
| void TAO_ESF_Copy_On_Write< PROXY, COLLECTION, ITERATOR, ACE_SYNCH_DECL >::for_each | ( | TAO_ESF_Worker< PROXY > * | worker | ) | [virtual] |
Iterate over the collection and invoke worker->work() for each member of the collection. This encapsulates
Implements TAO_ESF_Proxy_Collection< PROXY >.
| void TAO_ESF_Copy_On_Write< PROXY, COLLECTION, ITERATOR, ACE_SYNCH_DECL >::reconnected | ( | PROXY * | proxy | ) | [virtual] |
Insert an element into the collection. No errors can be raised if the element is already present. The collection assumes ownership, i.e. must invoke <proxy->_decr_refcnt()> if the element is already present in the collection.
Implements TAO_ESF_Proxy_Collection< PROXY >.
| void TAO_ESF_Copy_On_Write< PROXY, COLLECTION, ITERATOR, ACE_SYNCH_DECL >::shutdown | ( | void | ) | [virtual] |
The EC is shutting down, must release all the elements.
Implements TAO_ESF_Proxy_Collection< PROXY >.
Collection* TAO_ESF_Copy_On_Write< PROXY, COLLECTION, ITERATOR, ACE_SYNCH_DECL >::collection_ [private] |
The collection, with reference counting added.
ACE_SYNCH_CONDITION_T TAO_ESF_Copy_On_Write< PROXY, COLLECTION, ITERATOR, ACE_SYNCH_DECL >::cond_ [private] |
A condition variable to wait to synchronize multiple writers.
ACE_SYNCH_MUTEX_T TAO_ESF_Copy_On_Write< PROXY, COLLECTION, ITERATOR, ACE_SYNCH_DECL >::mutex_ [private] |
A mutex to serialize access to the collection pointer.
int TAO_ESF_Copy_On_Write< PROXY, COLLECTION, ITERATOR, ACE_SYNCH_DECL >::pending_writes_ [private] |
Number of pending writes.
int TAO_ESF_Copy_On_Write< PROXY, COLLECTION, ITERATOR, ACE_SYNCH_DECL >::writing_ [private] |
If non-zero then a thread is changing the collection. Many threads can use the collection simulatenously, but only one change it.
