Detailed Description

A reactive observer strategy.

This class simply keeps the information about the current list of observers, whenever the list of consumers and/or suppliers changes in queries the EC, computes the global subscription and/or publication list and sends the update message to all the observers. When an observer isn't reachable it is removed from the observer list.

Memory Management

It assumes ownership of the <lock>, but not of the Event_Channel.

Member Function Documentation

void TAO_EC_Reactive_ObserverStrategy::consumer_qos_update (  TAO_EC_ProxyPushSupplier *supplier  ACE_ENV_ARG_DECL  )  [protected, virtual]

Recompute EC consumer subscriptions and send them out to all observers. Reimplemented from TAO_EC_Basic_ObserverStrategy.

int TAO_EC_Reactive_ObserverStrategy::create_observer_map (  Observer_Map &map  ACE_ENV_ARG_DECL  )  [protected]

Copies all current observers into a map and passes it back to the caller through map. Returns: Returns the size of the map.

void TAO_EC_Reactive_ObserverStrategy::observer_not_exists (  Observer_Entry &observer  ACE_ENV_ARG_DECL  )  [protected]

The observer doesn't exist anymore.

void TAO_EC_Reactive_ObserverStrategy::supplier_qos_update (  TAO_EC_ProxyPushConsumer *consumer  ACE_ENV_ARG_DECL  )  [protected, virtual]

Recompute EC supplier publications and send them out to all observers. Reimplemented from TAO_EC_Basic_ObserverStrategy.
