Public Methods | |
virtual | ~TAO_EC_Supplier_Filter (void) |
Destructor. | |
virtual void | bind (TAO_EC_ProxyPushConsumer* consumer) = 0 |
virtual void | unbind (TAO_EC_ProxyPushConsumer* consumer) = 0 |
virtual void | connected (TAO_EC_ProxyPushSupplier *supplier, CORBA::Environment &env) = 0 |
Concrete implementations can use this methods to keep track of the consumers interested in this events. | |
virtual void | reconnected (TAO_EC_ProxyPushSupplier *supplier, CORBA::Environment &env) = 0 |
virtual void | disconnected (TAO_EC_ProxyPushSupplier *supplier, CORBA::Environment &env) = 0 |
virtual void | shutdown (CORBA::Environment &env) = 0 |
The event channel is shutting down. | |
virtual void | push (const RtecEventComm::EventSet &event, CORBA::Environment &) = 0 |
The ProxyPushConsumer delegates on this class to actually send the event. | |
virtual CORBA::ULong | _incr_refcnt (void) = 0 |
Increment and decrement the reference count, locking must be provided by the user. | |
virtual CORBA::ULong | _decr_refcnt (void) = 0 |
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.

Reimplemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter. |
|
Increment and decrement the reference count, locking must be provided by the user.
Reimplemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter. |

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 in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_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.
