Detailed Description

The strategy to handle observers for the Event Channel subscriptions and publication.

The Event Channel supports Observers for the set of subscriptions and publications. This is used to implement federations of event channels, either through UDP (multicast and unicast) and/or regular CORBA calls. This behavior of the EC is strategized to avoid overhead when no gateways are needed.

Member Function Documentation

virtual RtecEventChannelAdmin::Observer_Handle TAO_EC_ObserverStrategy::append_observer (  RtecEventChannelAdmin::Observer_ptr  ACE_ENV_ARG_DECL  )  throw ( CORBA::SystemException, RtecEventChannelAdmin::EventChannel::SYNCHRONIZATION_ERROR, RtecEventChannelAdmin::EventChannel::CANT_APPEND_OBSERVER) [pure virtual]

The basic methods to support the EC strategies. Implemented in TAO_EC_Null_ObserverStrategy, and TAO_EC_Basic_ObserverStrategy.

virtual void TAO_EC_ObserverStrategy::connected (  TAO_EC_ProxyPushSupplier *  ACE_ENV_ARG_DECL_NOT_USED  )  [pure virtual]

Used by the EC to inform the ObserverStrategy that a Supplier has connected or disconnected from it. Implemented in TAO_EC_Null_ObserverStrategy, and TAO_EC_Basic_ObserverStrategy.

virtual void TAO_EC_ObserverStrategy::connected (  TAO_EC_ProxyPushConsumer *  ACE_ENV_ARG_DECL_NOT_USED  )  [pure virtual]

Used by the EC to inform the ObserverStrategy that a Consumer has connected or disconnected from it. Implemented in TAO_EC_Null_ObserverStrategy, and TAO_EC_Basic_ObserverStrategy.

virtual void TAO_EC_ObserverStrategy::disconnected (  TAO_EC_ProxyPushSupplier *  ACE_ENV_ARG_DECL_NOT_USED  )  [pure virtual]

Implemented in TAO_EC_Null_ObserverStrategy, and TAO_EC_Basic_ObserverStrategy.

virtual void TAO_EC_ObserverStrategy::disconnected (  TAO_EC_ProxyPushConsumer *  ACE_ENV_ARG_DECL_NOT_USED  )  [pure virtual]

Implemented in TAO_EC_Null_ObserverStrategy, and TAO_EC_Basic_ObserverStrategy.

virtual void TAO_EC_ObserverStrategy::remove_observer (  RtecEventChannelAdmin::Observer_Handle  ACE_ENV_ARG_DECL  )  throw ( CORBA::SystemException, RtecEventChannelAdmin::EventChannel::SYNCHRONIZATION_ERROR, RtecEventChannelAdmin::EventChannel::CANT_REMOVE_OBSERVER) [pure virtual]

Implemented in TAO_EC_Null_ObserverStrategy, and TAO_EC_Basic_ObserverStrategy.
