Detailed Description

Filter the events on each supplier.

This is a filtering strategy for the suppliers. In this particular case we keep a collection of the consumers that could potentially be interested in any event generated by a particular supplier. This minimizes the amount of consumers touched by the EC when dispatching an event.

Member Function Documentation

void TAO_EC_Per_Supplier_Filter::bind

(

TAO_EC_ProxyPushConsumer *

consumer

)

[virtual]

Whenever a ProxyPushConsumer is initialized it calls this method to inform the Supplier_Filter of its identity. Strategies that do not keep ProxyPushConsumer specific information, or that are shared between multiple ProxyPushConsumers can ignore this message.

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::unbind

(

TAO_EC_ProxyPushConsumer *

consumer

)

[virtual]

Wheneve a ProxyPushConsumer is about to be destroyed it calls this method to inform the Supplier_Filter that it should release any resources related to it. Supplier_Filter strategies that are bound to a particular ProxyConsumer can use this opportunity to destroy themselves; filter strategies that do not keep ProxyPushConsumer specific information can simply ignore the message.

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::connected

(

TAO_EC_ProxyPushSupplier *

supplier

)

[virtual]

Concrete implementations can use this methods to keep track of the consumers interested in this events.

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::reconnected

(

TAO_EC_ProxyPushSupplier *

supplier

)

[virtual]

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::disconnected

(

TAO_EC_ProxyPushSupplier *

supplier

)

[virtual]

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::shutdown

(

void

)

[virtual]

The event channel is shutting down.

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::push	(	const RtecEventComm::EventSet &	event,
		TAO_EC_ProxyPushConsumer *	consumer
	)			[virtual]

The ProxyPushConsumer delegates on this class to actually send the event.

Implements TAO_EC_Supplier_Filter.

void TAO_EC_Per_Supplier_Filter::push_scheduled_event	(	RtecEventComm::EventSet &	event,
		const TAO_EC_QOS_Info &	event_info
	)			[virtual]

Events are first scheduled by the TAO_EC_Scheduling_Strategy, and then pushed through this class again.

Implements TAO_EC_Supplier_Filter.

CORBA::ULong TAO_EC_Per_Supplier_Filter::_decr_refcnt

(

void

)

[virtual]

Implements TAO_EC_Supplier_Filter.

CORBA::ULong TAO_EC_Per_Supplier_Filter::_incr_refcnt

(

void

)

[virtual]

Increment and decrement the reference count, locking must be provided by the user.

Implements TAO_EC_Supplier_Filter.
