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.

This control tries to reconnect to the consumer ec incase of a connection loss and then does a reconnect when the connection is back again. When also a restart of the consumer ec must be handled correctly, then the consumer ec must use a persistent IOR.

Constructor & Destructor Documentation

TAO_ECG_Reconnect_ConsumerEC_Control::TAO_ECG_Reconnect_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_Reconnect_ConsumerEC_Control::~TAO_ECG_Reconnect_ConsumerEC_Control (  void   )  [virtual]

Destructor.

Member Function Documentation

int TAO_ECG_Reconnect_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_Reconnect_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_Reconnect_ConsumerEC_Control::handle_timeout (  const ACE_Time_Value &  tv, const void *  arg )

Receive the timeout from the adapter.

void TAO_ECG_Reconnect_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.

void TAO_ECG_Reconnect_ConsumerEC_Control::reconnect (  ACE_ENV_SINGLE_ARG_DECL   )  [private]

Reconnect to the consumer ec.

int TAO_ECG_Reconnect_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_Reconnect_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.

void TAO_ECG_Reconnect_ConsumerEC_Control::try_reconnect (  ACE_ENV_SINGLE_ARG_DECL   )  [private]

Look if we can reconnect again.
