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 ( void ) [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 ) [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 ) [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.
