| virtual void | unbind (TAO_EC_ProxyPushConsumer* consumer) |
| virtual void | connected (TAO_EC_ProxyPushSupplier* supplier, CORBA::Environment &env) |

| virtual void | disconnected (TAO_EC_ProxyPushSupplier* supplier, CORBA::Environment &env) |
| virtual void | shutdown (CORBA::Environment &env) |
| The event channel is shutting down. | |
| virtual void | push (const RtecEventComm::EventSet& event, CORBA::Environment &) |

Private Attributes | |
| TAO_EC_Event_Channel* | event_channel_ |
| The event channel, used to locate the set of consumers. | |
| TAO_EC_ProxyPushConsumer* | consumer_ |
| The proxy for the supplier we are bound to. | |
| TAO_ESF_Proxy_Collection<TAO_EC_ProxyPushSupplier>* | collection_ |
| Keep the collection of proxies for the consumers that may be interested in our events. | |
| CORBA::ULong | refcnt_ |
| Reference counting. | |
| TAO_SYNCH_MUTEX | lock_ |
| Locking. | |
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.

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. Reimplemented from TAO_EC_Supplier_Filter. |

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.
