Detailed Description

TAO_Notify_EventListener.

All entities interested in receiving events can implement this interface and subscribe with the Event Manager. During subscription, the Listener must specify what kind of events it is interested in.

Member Function Documentation

virtual void TAO_Notify_EventListener::dispatch_event (  TAO_Notify_Event &event    ACE_ENV_ARG_DECL )  [pure virtual]

Callback methods to supply the event to the listener. Reimplemented in TAO_Notify_ConsumerAdmin_i, TAO_Notify_ProxySupplier, TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::StructuredProxyPushSupplier >, TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::ProxyPushSupplier >, and TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::SequenceProxyPushSupplier >.

virtual CORBA::Boolean TAO_Notify_EventListener::evaluate_filter (  TAO_Notify_Event &    event, CORBA::Boolean eval_parent    ACE_ENV_ARG_DECL )  [pure virtual]

Evaluates true if this event is acceptable by the listener. The <eval_parent> is a hint to the listener to help it determine if its wise to evaluate the parents filter too. This helps in implementing the "interfilter group operator" logic. Reimplemented in TAO_Notify_ConsumerAdmin_i, TAO_Notify_ProxySupplier, TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::StructuredProxyPushSupplier >, TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::ProxyPushSupplier >, and TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::SequenceProxyPushSupplier >.

virtual TAO_Notify_Worker_Task* TAO_Notify_EventListener::event_dispatch_task (  void    )  [pure virtual]

The Worker task associated with the event listener for event dispatching. Reimplemented in TAO_Notify_ConsumerAdmin_i, TAO_Notify_ProxySupplier, TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::StructuredProxyPushSupplier >, TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::ProxyPushSupplier >, and TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::SequenceProxyPushSupplier >.

virtual TAO_Notify_Worker_Task* TAO_Notify_EventListener::filter_eval_task (  void    )  [pure virtual]

The Worker task associated with the event listener for filter evaluation. Reimplemented in TAO_Notify_ConsumerAdmin_i, TAO_Notify_ProxySupplier, TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::StructuredProxyPushSupplier >, TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::ProxyPushSupplier >, and TAO_Notify_ProxySupplier< POA_CosNotifyChannelAdmin::SequenceProxyPushSupplier >.

virtual void TAO_Notify_EventListener::shutdown (  ACE_ENV_SINGLE_ARG_DECL    )  [pure virtual]

Ask the listener to relinquish any bindings and prepare to be disposed. Reimplemented in TAO_Notify_ConsumerAdmin_i, TAO_Notify_ProxyPushSupplier_i, TAO_Notify_SequenceProxyPushSupplier_i, and TAO_Notify_StructuredProxyPushSupplier_i.
