Detailed Description

SupplierControl.

Defines the interface for the supplier control strategy. This strategy handles misbehaving or failing suppliers. = MEMORY MANAGEMENT = LOCKING = TODO

Constructor & Destructor Documentation

TAO_CEC_Reactive_SupplierControl()

TAO_CEC_Reactive_SupplierControl::TAO_CEC_Reactive_SupplierControl	(	const ACE_Time_Value &	rate,
		const ACE_Time_Value &	timeout,
		unsigned int	retries,
		TAO_CEC_EventChannel *	event_channel,
		CORBA::ORB_ptr	orb )

Constructor. It does not assume ownership of the event_channel parameter.

~TAO_CEC_Reactive_SupplierControl()

TAO_CEC_Reactive_SupplierControl::~TAO_CEC_Reactive_SupplierControl ( )

virtual

Constructor for the typed ec.

Member Function Documentation

activate()

int TAO_CEC_Reactive_SupplierControl::activate ( )

virtual

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

Reimplemented from TAO_CEC_SupplierControl.

handle_timeout()

void TAO_CEC_Reactive_SupplierControl::handle_timeout	(	const ACE_Time_Value &	tv,
		const void *	arg )

Receive the timeout from the adapter.

need_to_disconnect()

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.

query_suppliers()

void TAO_CEC_Reactive_SupplierControl::query_suppliers ( )

private

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

shutdown()

int TAO_CEC_Reactive_SupplierControl::shutdown ( )

virtual

Reimplemented from TAO_CEC_SupplierControl.

successful_transmission()

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.

supplier_not_exist() [1/2]

void TAO_CEC_Reactive_SupplierControl::supplier_not_exist ( TAO_CEC_ProxyPullConsumer * 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_CEC_SupplierControl.

supplier_not_exist() [2/2]

void TAO_CEC_Reactive_SupplierControl::supplier_not_exist ( TAO_CEC_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_CEC_SupplierControl.

system_exception()

void TAO_CEC_Reactive_SupplierControl::system_exception ( TAO_CEC_ProxyPullConsumer * proxy, CORBA::SystemException &  )

virtual

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

Reimplemented from TAO_CEC_SupplierControl.
