Member Function Documentation

void TAO_ESF_Copy_On_Write::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::disconnected ( PROXY * proxy ) [virtual]

Remove an element from the collection.

Implements TAO_ESF_Proxy_Collection< PROXY >.

void TAO_ESF_Copy_On_Write::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::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::shutdown ( void ) [virtual]

The EC is shutting down, must release all the elements.

Implements TAO_ESF_Proxy_Collection< PROXY >.
