Detailed Description

TAO_Notify_Event_Map.

This is a compound container consisting of:

A "recipient" map : mapping between an event and its subscriibers
Lists of current events being subscribed, published.
Lists of subscriptions, publications update listeners.

Member Data Documentation

TAO_Notify_Collection_Factory* TAO_Notify_Event_Map::collection_factory_ [protected]

Collection objects factory.

TAO_Notify_EventListener_List* TAO_Notify_Event_Map::default_subscription_list_ [protected]

Save a reference to the default list, we don't want to spend time looking for it in the <event_recipient_map>.

TAO_Notify_EMO_Factory* TAO_Notify_Event_Map::emo_factory_ [protected]

Evenet Manager Objects factory.

EVENT_RECIPIENT_MAP TAO_Notify_Event_Map::event_recipient_map_ [protected]

A Map of event types and the groups of event listeners interested in them.
The keys of the map are a list of events that consumers have currently subscribed for.

TAO_Notify_UpdateListener_List* TAO_Notify_Event_Map::publication_change_listeners_ [protected]

This is a list of listeners that want to be notified if the publications from suppliers changes the <publication_list_>.

TAO_Notify_EventType_List TAO_Notify_Event_Map::publication_list_ [protected]

The list of event types that are being currently published by suppliers.

TAO_Notify_UpdateListener_List* TAO_Notify_Event_Map::subscription_change_listeners_ [protected]

This is a list of listeners that want to be notified if the subsciptions from consumers changes the <event_recipient_map_> keys.

TAO_Notify_EventType_List TAO_Notify_Event_Map::subscription_list_ [protected]

The list of event types that are being currently subscribed to by consumers.
This list is the same as the list of keys in the <event_recepient_map>. We keep a copy of that list here to reduce contention for the map which will be accessed for every event that enters the system.
