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 ( void ) [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 ) [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.
