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.
