Member Function Documentation

int TAO_CEC_Reactive_SupplierControl::activate void   )  [virtual]
 

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

Reimplemented from TAO_CEC_SupplierControl.

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

Receive the timeout from the adapter.

bool TAO_CEC_Reactive_SupplierControl::need_to_disconnect PortableServer::ServantBase proxy  )  [virtual]
 

Do we need to disconnect this supplier? The parameter type for proxy is PortableServer::ServantBase* due to the fact that this method will be used for TAO_CEC_ProxyPushSupplier's and TAO_CEC_ProxyPullSupplier's.

Reimplemented from TAO_CEC_SupplierControl.

void TAO_CEC_Reactive_SupplierControl::query_suppliers ACE_ENV_SINGLE_ARG_DECL   )  [private]
 

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

int TAO_CEC_Reactive_SupplierControl::shutdown void   )  [virtual]
 

Reimplemented from TAO_CEC_SupplierControl.

void TAO_CEC_Reactive_SupplierControl::successful_transmission PortableServer::ServantBase proxy  )  [virtual]
 

Allow others to inform us when a send or receive was successful.

Reimplemented from TAO_CEC_SupplierControl.

void TAO_CEC_Reactive_SupplierControl::supplier_not_exist TAO_CEC_ProxyPullConsumer *proxy  ACE_ENV_ARG_DECL_NOT_USED  )  [virtual]
 

Invoked by helper classes when they detect that a supplier does not exists (i.e. _non_existent() returns true and/or the CORBA::OBJECT_NOT_EXIST exception has been raised).

Reimplemented from TAO_CEC_SupplierControl.

void TAO_CEC_Reactive_SupplierControl::supplier_not_exist TAO_CEC_ProxyPushConsumer *proxy  ACE_ENV_ARG_DECL_NOT_USED  )  [virtual]
 

Invoked by helper classes when they detect that a supplier does not exists (i.e. _non_existent() returns true and/or the CORBA::OBJECT_NOT_EXIST exception has been raised).

Reimplemented from TAO_CEC_SupplierControl.

void TAO_CEC_Reactive_SupplierControl::system_exception TAO_CEC_ProxyPullConsumer 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_SupplierControl.
