Constructor & Destructor Documentation

TAO_BEGIN_VERSIONED_NAMESPACE_DECL TAO_CEC_Reactive_SupplierControl::TAO_CEC_Reactive_SupplierControl	(	const ACE_Time_Value &	rate,
		const ACE_Time_Value &	timeout,
		unsigned int	retries,

		CORBA::ORB_ptr	orb
	)

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

TAO_CEC_Reactive_SupplierControl::~TAO_CEC_Reactive_SupplierControl

Member Function Documentation

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

Receive the timeout from the adapter.

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.

int TAO_CEC_Reactive_SupplierControl::shutdown

(

void

)

[virtual]

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.

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::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.

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::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::query_suppliers

(

void

)

[private]

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