Detailed Description

Consumer event channel control.

Defines the interface for the consumer event channel control strategy. This strategy handles misbehaving or failing consumer event channels.

Constructor & Destructor Documentation

TAO_ECG_Reactive_ConsumerEC_Control::TAO_ECG_Reactive_ConsumerEC_Control ( const ACE_Time_Value & rate,

const ACE_Time_Value & timeout,

TAO_EC_Gateway_IIOP * gateway,

CORBA::ORB_ptr orb

)

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

TAO_ECG_Reactive_ConsumerEC_Control::~TAO_ECG_Reactive_ConsumerEC_Control ( void ) [virtual]

Destructor.

Member Function Documentation

int TAO_ECG_Reactive_ConsumerEC_Control::activate ( void ) [virtual]

Activate any internal threads or timers used to poll the state of the event channel.
Reimplemented from TAO_ECG_ConsumerEC_Control.

void TAO_ECG_Reactive_ConsumerEC_Control::event_channel_not_exist ( TAO_EC_Gateway_IIOP *gateway ACE_ENV_ARG_DECL_NOT_USED ) [virtual]

When pushing an event to the event channel 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_ECG_ConsumerEC_Control.

void TAO_ECG_Reactive_ConsumerEC_Control::handle_timeout ( const ACE_Time_Value & tv,

const void * arg

)

Receive the timeout from the adapter.

void TAO_ECG_Reactive_ConsumerEC_Control::query_eventchannel ( 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_ECG_Reactive_ConsumerEC_Control::shutdown ( void ) [virtual]

Shutdown any internal threads or timers used to poll the state of the event channel.
Reimplemented from TAO_ECG_ConsumerEC_Control.

void TAO_ECG_Reactive_ConsumerEC_Control::system_exception ( TAO_EC_Gateway_IIOP * gateway,

CORBA::SystemException & ACE_ENV_ARG_DECL_NOT_USED

) [virtual]

Some system exception was raised while trying to contact the event channel
Reimplemented from TAO_ECG_ConsumerEC_Control.
