Detailed Description

Filter the events on each supplier.

This is a filtering strategy for the suppliers. In this particular case we keep a collection of the consumers that could potentially be interested in any event generated by a particular supplier. This minimizes the amount of consumers touched by the EC when dispatching an event.


Constructor & Destructor Documentation

TAO_EC_Per_Supplier_Filter::TAO_EC_Per_Supplier_Filter TAO_EC_Event_Channel_Base ec  ) 
 

Constructor.

TAO_EC_Per_Supplier_Filter::~TAO_EC_Per_Supplier_Filter void   )  [virtual]
 

Destructor.


Member Function Documentation

CORBA::ULong TAO_EC_Per_Supplier_Filter::_decr_refcnt void   )  [virtual]
 

Implements TAO_EC_Supplier_Filter.

CORBA::ULong TAO_EC_Per_Supplier_Filter::_incr_refcnt void   )  [virtual]
 

Increment and decrement the reference count, locking must be provided by the user.

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_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.

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::connected TAO_EC_ProxyPushSupplier *supplier  ACE_ENV_ARG_DECL  )  [virtual]
 

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

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::disconnected TAO_EC_ProxyPushSupplier *supplier  ACE_ENV_ARG_DECL  )  [virtual]
 

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::push const RtecEventComm::EventSet event,
TAO_EC_ProxyPushConsumer *consumer  ACE_ENV_ARG_DECL_NOT_USED
[virtual]
 

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

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::push_scheduled_event RtecEventComm::EventSet event,
const TAO_EC_QOS_Info &event_info  ACE_ENV_ARG_DECL
[virtual]
 

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

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::reconnected TAO_EC_ProxyPushSupplier *supplier  ACE_ENV_ARG_DECL  )  [virtual]
 

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::shutdown ACE_ENV_SINGLE_ARG_DECL   )  [virtual]
 

The event channel is shutting down.

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_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.

Implements TAO_EC_Supplier_Filter.
