Detailed Description

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    ACE_ENV_ARG_DECL_NOT_USED )  [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    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_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 (  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_CEC_Reactive_ConsumerControl::shutdown (  void    )  [virtual]

Reimplemented from TAO_CEC_ConsumerControl.

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

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