Detailed Description

Implementation of CosNotifyChannelAdmin::EventChannelFactory.

Member Typedef Documentation

typedef TAO_Notify_Refcountable_Guard_T< TAO_Notify_EventChannelFactory > TAO_Notify_EventChannelFactory::Ptr

Reimplemented from TAO_Notify_Refcountable.

Constructor & Destructor Documentation

TAO_Notify_EventChannelFactory::TAO_Notify_EventChannelFactory ( void )

Constructor.

TAO_Notify_EventChannelFactory::~TAO_Notify_EventChannelFactory ( ) [virtual]

Destructor.

Member Function Documentation

void TAO_Notify_EventChannelFactory::_add_ref ( void ) [virtual]

= ServantBase Methods

void TAO_Notify_EventChannelFactory::_remove_ref ( void ) [virtual]

CosNotifyChannelAdmin::EventChannelFactory_ptr TAO_Notify_EventChannelFactory::activate_self ( void )

bool TAO_Notify_EventChannelFactory::change_to_parent ( void ) [virtual]

Send change to parent.

Override this if you don't expect to have a parent (top level of tree) private virtual because this should only be called from send_change()

Returns:: false if save will never happen

Reimplemented from TAO_Notify::Topology_Object.

CosNotifyChannelAdmin::EventChannel_ptr TAO_Notify_EventChannelFactory::create_channel	(	const CosNotification::QoSProperties &	initial_qos,
		const CosNotification::AdminProperties &	initial_admin,
		CosNotifyChannelAdmin::ChannelID_out	id

		const CosNotification::AdminProperties &	initial_admin,
		CosNotifyChannelAdmin::ChannelID_out	id,
		const char *	name
	)		`[virtual]`

This method is called by the Notify_Service when the event channel is automatically created and bound in the name service.

TAO_Notify_Object::ID TAO_Notify_EventChannelFactory::get_id ( void ) const [virtual]

Find the id associated with topology object.

A bit of a hack because id is unknown to Topology_Object the get_id returns the same thing as id -- we just need someone to find it for us.

Reimplemented from TAO_Notify::Topology_Object.

bool TAO_Notify_EventChannelFactory::handle_change ( void )

Handle change notifications.

void TAO_Notify_EventChannelFactory::init ( PortableServer::POA_ptr poa )

Init the factory.

CORBA::Boolean TAO_Notify_EventChannelFactory::is_alive ( void ) [private, virtual]

bool TAO_Notify_EventChannelFactory::is_persistent ( void ) const [virtual]

Should this object be saved?

This is a way for send_change() and save_persistent() to find out if this object has a persistent QoS connection property.

Returns:: true (default) if object should be saved.

Reimplemented from TAO_Notify::Topology_Object.

TAO_Notify::Topology_Object * TAO_Notify_EventChannelFactory::load_child	(	const ACE_CString &	type,
		CORBA::Long	id,
		const TAO_Notify::NVPList &	attrs
	)		`[virtual]`

Create a child of the appropriate type and return it.

Use "type" as passed in to determine what kind of child (supporting the Topology_Object interface) to create and return. Inform it of its new ID.

Reimplemented from TAO_Notify::Topology_Object.

void TAO_Notify_EventChannelFactory::load_event_persistence ( void )

void TAO_Notify_EventChannelFactory::load_topology ( void )

Use the registered Topology_Factory to create a loader, and load the topology. If no Topology_Factory is registered then nothing will be loaded.

void TAO_Notify_EventChannelFactory::reconnect ( void ) [virtual]

Re-establish connections that we had before a shutdown.

After a topology restore, this method is called so we can reconnect to any external objects with whom we were interacting. We should call the reconnect() method on all of our children to give them the chance to do the same.

Reimplemented from TAO_Notify::Topology_Savable.

NotifyExt::ReconnectionRegistry::ReconnectionID TAO_Notify_EventChannelFactory::register_callback ( NotifyExt::ReconnectionCallback_ptr reconnection ) [private, virtual]

void TAO_Notify_EventChannelFactory::release ( void ) [private, virtual]

Release this object.

Implements TAO_Notify_Refcountable.

void TAO_Notify_EventChannelFactory::remove ( TAO_Notify_EventChannel * channel ) [virtual]

Remove channel from the <ec_container_>

void TAO_Notify_EventChannelFactory::save_persistent ( TAO_Notify::Topology_Saver & saver ) [virtual]

Save our state to a Topology_Saver.

Use the methods of a Topology_Saver to store all information we want persisted. This function is called by our parent, which gives us a saver to use. In turn, we must call this function on all of our children. The implementation should look like: bool change = this->self_changed_; this->self_changed_ = false; this->children_changed_ = false; if (is_persistent ()) { bool want_all_children = saver.begin_object( this->id(), type, attrs, change); for all children { if (want_all_children || child.is_changed()) { child.save_persistent(saver); } } for all deleted children { saver.delete_child(child_type, child_id); } saver.end_object(this->id(), type); )

Implements TAO_Notify::Topology_Savable.
