Detailed Description

The strategy to filter close to the supplier.

After an event is received by the a ProxyPushConsumer it must be dispatched to the right set of ProxyPushSuppliers; determining this set is the task of this class. Notice that this is in fact a filter, and enforces (in part) the subscriptions and publications of the Event Service clients. Several implementations are possible:

Destructor.


Member Function Documentation

virtual CORBA::ULong TAO_EC_Supplier_Filter::_decr_refcnt void   )  [pure virtual]
 

Implemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter.

virtual CORBA::ULong TAO_EC_Supplier_Filter::_incr_refcnt void   )  [pure virtual]
 

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

Implemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter.

virtual void TAO_EC_Supplier_Filter::bind TAO_EC_ProxyPushConsumer consumer  )  [pure 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.

Implemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter.

virtual void TAO_EC_Supplier_Filter::connected TAO_EC_ProxyPushSupplier *supplier  ACE_ENV_ARG_DECL  )  [pure virtual]
 

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

Implemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter.

virtual void TAO_EC_Supplier_Filter::disconnected TAO_EC_ProxyPushSupplier *supplier  ACE_ENV_ARG_DECL  )  [pure virtual]
 

Implemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter.

virtual void TAO_EC_Supplier_Filter::push const RtecEventComm::EventSet event,
TAO_EC_ProxyPushConsumer *consumer  ACE_ENV_ARG_DECL
[pure virtual]
 

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

Implemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter.

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

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

Implemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter.

virtual void TAO_EC_Supplier_Filter::reconnected TAO_EC_ProxyPushSupplier *supplier  ACE_ENV_ARG_DECL  )  [pure virtual]
 

Implemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter.

virtual void TAO_EC_Supplier_Filter::shutdown ACE_ENV_SINGLE_ARG_DECL   )  [pure virtual]
 

The event channel is shutting down.

Implemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter.

virtual void TAO_EC_Supplier_Filter::unbind TAO_EC_ProxyPushConsumer consumer  )  [pure 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.

Implemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter.
