template<class PROXY , class COLLECTION , class ITERATOR , ACE_SYNCH_DECL >

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 >.

template<class PROXY , class COLLECTION , class ITERATOR , ACE_SYNCH_DECL >

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 >.

template<class PROXY , class COLLECTION , class ITERATOR , ACE_SYNCH_DECL >

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 >.

template<class PROXY , class COLLECTION , class ITERATOR , ACE_SYNCH_DECL >

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 >.

template<class PROXY , class COLLECTION , class ITERATOR , ACE_SYNCH_DECL >

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 >.

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.
