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:
|
virtual |
Destructor.
|
pure virtual |
Implemented in TAO_EC_Per_Supplier_Filter, and TAO_EC_Trivial_Supplier_Filter.
|
pure virtual |
Increment and decrement the reference count, locking must be provided by the user.

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.

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

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

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

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.
