Detailed Description

SupplierControl.

Defines the interface for the supplier control strategy. This strategy handles misbehaving or failing suppliers.


Constructor & Destructor Documentation

TAO_EC_Reactive_SupplierControl::TAO_EC_Reactive_SupplierControl 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_SupplierControl::~TAO_EC_Reactive_SupplierControl void   )  [virtual]
 

Destructor.


Member Function Documentation

int TAO_EC_Reactive_SupplierControl::activate void   )  [virtual]
 

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

Reimplemented from TAO_EC_SupplierControl.

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

Receive the timeout from the adapter.

void TAO_EC_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_EC_Reactive_SupplierControl::shutdown void   )  [virtual]
 

Reimplemented from TAO_EC_SupplierControl.

void TAO_EC_Reactive_SupplierControl::supplier_not_exist TAO_EC_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_EC_SupplierControl.

void TAO_EC_Reactive_SupplierControl::system_exception TAO_EC_ProxyPushConsumer proxy,
CORBA::SystemException ACE_ENV_ARG_DECL_NOT_USED
[virtual]
 

Some system exception was raised while trying to contact the supplier

Reimplemented from TAO_EC_SupplierControl.
