Public Methods

 TAO_CEC_Reactive_ConsumerControl (const ACE_Time_Value &rate, TAO_CEC_EventChannel *event_channel, CORBA::ORB_ptr orb)
 Constructor. It does not assume ownership of the <event_channel> parameter.

virtual ~TAO_CEC_Reactive_ConsumerControl (void)
 destructor...

void handle_timeout (const ACE_Time_Value &tv, const void* arg)
 Receive the timeout from the adapter.

virtual int activate (void)
 Activate any internal threads or timers used to poll the state of the consumers.

virtual int shutdown (void)
virtual void consumer_not_exist (TAO_CEC_ProxyPushSupplier *proxy, CORBA::Environment &)
virtual void consumer_not_exist (TAO_CEC_ProxyPullSupplier *proxy, CORBA::Environment &)
virtual void system_exception (TAO_CEC_ProxyPushSupplier *proxy, CORBA::SystemException &, CORBA::Environment &)
 Some system exception was rasied while trying to push an event.


Private Methods

void query_consumers (CORBA::Environment &ACE_TRY_ENV)
 Check if the consumers still exists. It is a helper method for handle_timeout() to isolate the exceptions.


Private Attributes

ACE_Time_Value rate_
 The polling rate.

TAO_CEC_ConsumerControl_Adapter adapter_
 The Adapter for the reactor events.

TAO_CEC_EventChannelevent_channel_
 The event channel.

CORBA::ORB_var orb_
 The ORB.

CORBA::PolicyCurrent_var policy_current_
 To control the timeout policy in the thread.

CORBA::PolicyList policy_list_
 Precomputed policy list to the set timeout.

ACE_Reactorreactor_
 The ORB reactor.

ConsumerControl.

Defines the interface for the consumer control strategy. This strategy handles misbehaving or failing consumers. = MEMORY MANAGMENT = LOCKING = TODO

Member Function Documentation

int TAO_CEC_Reactive_ConsumerControl::activate ( void ) [virtual]
 

Activate any internal threads or timers used to poll the state of the consumers.

Reimplemented from TAO_CEC_ConsumerControl.

void TAO_CEC_Reactive_ConsumerControl::consumer_not_exist ( TAO_CEC_ProxyPullSupplier * proxy,
CORBA::Environment & ACE_TRY_ENV ) [virtual]
 

Invoked by helper classes when they detect that a consumer no longer exists (i.e. _non_existent() returns true and/or the CORBA::OBJECT_NOT_EXIST exception has been raised).

Reimplemented from TAO_CEC_ConsumerControl.

void TAO_CEC_Reactive_ConsumerControl::consumer_not_exist ( TAO_CEC_ProxyPushSupplier * proxy,
CORBA::Environment & ACE_TRY_ENV ) [virtual]
 

When pushing an event to the consumer a CORBA::OBJECT_NOT_EXIST exception was raised. The only interpretation is that the object has been destroyed. The strategy has to (at the very least), reclaim all the resources attached to that object.

Reimplemented from TAO_CEC_ConsumerControl.

void TAO_CEC_Reactive_ConsumerControl::handle_timeout ( const ACE_Time_Value & tv,
const void * arg )
 

Receive the timeout from the adapter.

void TAO_CEC_Reactive_ConsumerControl::query_consumers ( CORBA::Environment & ACE_TRY_ENV ) [private]
 

Check if the consumers still exists. It is a helper method for handle_timeout() to isolate the exceptions.

int TAO_CEC_Reactive_ConsumerControl::shutdown ( void ) [virtual]
 

Reimplemented from TAO_CEC_ConsumerControl.

void TAO_CEC_Reactive_ConsumerControl::system_exception ( TAO_CEC_ProxyPushSupplier * proxy,
CORBA::SystemException &,
CORBA::Environment & ACE_TRY_ENV ) [virtual]
 

Some system exception was rasied while trying to push an event.

Reimplemented from TAO_CEC_ConsumerControl.
