Implement the RtecEventChannelAdmin::ProxyPushSupplier interface, remember that this class is used to communicate with a PushConsumer, so, in effect, this is the ambassador for a consumer inside the event channel.
It does not assume ownership of the TAO_EC_Dispatching object. It makes a copy of the ConsumerQOS and the consumer object reference.
Locking is strategized, the event channel acts as a factory for the locking strategies.

const TAO_EC_QOS_Info &qos_info | ACE_ENV_ARG_DECL | |||
) | [virtual] |
This is used for computing the scheduling dependencies:
Leaf filters check if the header could be matched, similar to the can_match() method; if it does they return 1, and 0 otherwise. Intermediate nodes always return 0.
This is used to build precise dependencies between the suppliers and the leaf of the filters that accept that event. Notice that only the nodes doing scheduling recurse through the list, so in configurations that do no require scheduling the recursion stops fairly soon.
Implements TAO_EC_Filter.
int TAO_EC_ProxyPushSupplier::can_match | ( | const RtecEventComm::EventHeader & | header | ) | const [virtual] |
Returns 0 if an event with that header could never be accepted. This can used by the suppliers to filter out consumers that couldn't possibly be interested in their events. The rt_info and
Implements TAO_EC_Filter.
void TAO_EC_ProxyPushSupplier::cleanup_i | ( | void | ) | [protected] |
Release the child and the consumer.
void TAO_EC_ProxyPushSupplier::clear | ( | void | ) | [virtual] |
Clear any saved state, must reset and assume no events have been received.
Implements TAO_EC_Filter.
virtual void TAO_EC_ProxyPushSupplier::connected | ( | TAO_EC_ProxyPushSupplier *supplier | ACE_ENV_ARG_DECL | ) | [virtual] |
Usually implemented as no-ops, but some configurations may require this methods.
virtual void TAO_EC_ProxyPushSupplier::connected | ( | TAO_EC_ProxyPushConsumer *consumer | ACE_ENV_ARG_DECL | ) | [virtual] |
Concrete implementations can use this methods to keep track of the suppliers that publish its events.
ACE_INLINE void TAO_EC_ProxyPushSupplier::consumer | ( | RtecEventComm::PushConsumer_ptr | consumer | ) | [protected] |
Set the consumer, used by some implementations to change the policies used when invoking operations on the consumer.
ACE_INLINE RtecEventComm::PushConsumer_ptr TAO_EC_ProxyPushSupplier::consumer | ( | void | ) | const |
Return the consumer object reference. It returns nil() if it has not connected yet.

CORBA::Boolean TAO_EC_ProxyPushSupplier::consumer_non_existent | ( | CORBA::Boolean_out disconnected | ACE_ENV_ARG_DECL | ) |
Invoke the _non_existent() pseudo-operation on the consumer. If it is disconnected then it returns true and sets the <disconnected> flag.

Disconnect this from.

Filter this event, returns 1 if the event is accepted, 0 otherwise. Notice that there are two versions of the method, if the event is not const then filter can take ownership of the event.
