Detailed Description

ConsumerControl.

Defines the interface for the consumer control strategy. This strategy handles misbehaving or failing consumers.


Constructor & Destructor Documentation

TAO_EC_Reactive_ConsumerControl::TAO_EC_Reactive_ConsumerControl const ACE_Time_Value rate,
const ACE_Time_Value timeout,
TAO_EC_Event_Channel_Base event_channel,
CORBA::ORB_ptr  orb
 

Constructor. It does not assume ownership of the event_channel parameter.

TAO_EC_Reactive_ConsumerControl::~TAO_EC_Reactive_ConsumerControl void   )  [virtual]
 

Destructor.


Member Function Documentation

int TAO_EC_Reactive_ConsumerControl::activate void   )  [virtual]
 

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

Reimplemented from TAO_EC_ConsumerControl.

void TAO_EC_Reactive_ConsumerControl::consumer_not_exist TAO_EC_ProxyPushSupplier *proxy  ACE_ENV_ARG_DECL_NOT_USED  )  [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_EC_ConsumerControl.

void TAO_EC_Reactive_ConsumerControl::handle_timeout const ACE_Time_Value tv,
const void *  arg
 

Receive the timeout from the adapter.

void TAO_EC_Reactive_ConsumerControl::query_consumers ACE_ENV_SINGLE_ARG_DECL   )  [private]
 

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

int TAO_EC_Reactive_ConsumerControl::shutdown void   )  [virtual]
 

Reimplemented from TAO_EC_ConsumerControl.

void TAO_EC_Reactive_ConsumerControl::system_exception TAO_EC_ProxyPushSupplier proxy,
CORBA::SystemException ACE_ENV_ARG_DECL_NOT_USED
[virtual]
 

Some system exception was raised while trying to contact the consumer

Reimplemented from TAO_EC_ConsumerControl.
