Private Attributes

TAO_EC_Event_Channel_Base * event_channel_
 The event channel, used to locate the set of consumers.

Detailed Description

A null filtering strategy.

This strategy does no filtering, it is useful for backends of the CosEventChannel, testing and broadcasters; it uses the ConsumerAdmin to find all the consumers and pushes the event to all of them.

void TAO_EC_Trivial_Supplier_Filter::bind (  TAO_EC_ProxyPushConsumer *  consumer  )  [virtual]
 

Whenever a ProxyPushConsumer is initialized it calls this method to inform the Supplier_Filter of its identity. Strategies that do not keep ProxyPushConsumer specific information, or that are shared between multiple ProxyPushConsumers can ignore this message.

void TAO_EC_Trivial_Supplier_Filter::connected (  TAO_EC_ProxyPushSupplier *  supplier  )  [virtual]
 

Concrete implementations can use this methods to keep track of the consumers interested in this events.

void TAO_EC_Trivial_Supplier_Filter::push (  const RtecEventComm::EventSet &  event,
TAO_EC_ProxyPushConsumer *  consumer
)  [virtual]
 

The ProxyPushConsumer delegates on this class to actually send the event.

void TAO_EC_Trivial_Supplier_Filter::push_scheduled_event (  RtecEventComm::EventSet &  event,
const TAO_EC_QOS_Info &  event_info
)  [virtual]
 

Events are first scheduled by the TAO_EC_Scheduling_Strategy, and then pushed through this class again.

void TAO_EC_Trivial_Supplier_Filter::shutdown (  void   )  [virtual]
 

The event channel is shutting down.

void TAO_EC_Trivial_Supplier_Filter::unbind (  TAO_EC_ProxyPushConsumer *  consumer  )  [virtual]
 

Wheneve a ProxyPushConsumer is about to be destroyed it calls this method to inform the Supplier_Filter that it should release any resources related to it. Supplier_Filter strategies that are bound to a particular ProxyConsumer can use this opportunity to destroy themselves; filter strategies that do not keep ProxyPushConsumer specific information can simply ignore the message.
