Detailed Description

ConsumerControl.

Defines the interface for the consumer control strategy. This strategy handles misbehaving or failing consumers.

Constructor & Destructor Documentation

TAO_BEGIN_VERSIONED_NAMESPACE_DECL TAO_EC_Reactive_ConsumerControl::TAO_EC_Reactive_ConsumerControl	(	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.

Destructor.

Member Function Documentation

int TAO_EC_Reactive_ConsumerControl::activate

(

void

)

[virtual]

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

Reimplemented from TAO_EC_ConsumerControl.

void TAO_EC_Reactive_ConsumerControl::consumer_not_exist	(	TAO_EC_ProxyPushSupplier *	proxy,
		CORBA::Environment &
	)			[virtual]

When pushing an event to the consumer a CORBA::OBJECT_NOT_EXIST exception was raised. The only interpretation is that the object has been destroyed. The strategy has to (at the very least), reclaim all the resources attached to that object.

Reimplemented from TAO_EC_ConsumerControl.

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

Receive the timeout from the adapter.

void TAO_EC_Reactive_ConsumerControl::query_consumers

(

CORBA::Environment &

_ACE_CORBA_Environment_variable

)

[private]

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

int TAO_EC_Reactive_ConsumerControl::shutdown

(

void

)

[virtual]

Reimplemented from TAO_EC_ConsumerControl.

void TAO_EC_Reactive_ConsumerControl::system_exception	(	TAO_EC_ProxyPushSupplier *	proxy,
		CORBA::SystemException &	,
		CORBA::Environment &
	)			[virtual]

Some system exception was raised while trying to contact the consumer

Reimplemented from TAO_EC_ConsumerControl.
