Detailed Description

Base class for Persistent Topology Objects.

Topology objects must be derived from this class to allow themselves to be persisted. Note: virtual inheritance from TopologySavable is unnecessary, but HP ACC compiler warns if it's not there.

Constructor & Destructor Documentation

TAO_Notify::Topology_Object::Topology_Object

(

)

The constructor.

TAO_Notify::Topology_Object::~Topology_Object

(

)

[virtual]

The destructor.

Member Function Documentation

bool TAO_Notify::Topology_Object::change_to_parent

(

void

)

[private, 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 in TAO_Notify_EventChannelFactory.

TAO_Notify_Object::ID TAO_Notify::Topology_Object::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 in TAO_Notify_EventChannelFactory, and TAO_Notify_EventChannel.

void TAO_Notify::Topology_Object::get_id_path

(

TAO_Notify::IdVec &

id_path

)

const

Get the path of id's from the root to this object.

void TAO_Notify::Topology_Object::initialize

(

Topology_Parent *

topology_parent

)

[virtual]

Init this object with data from <rhs>.

bool TAO_Notify::Topology_Object::is_changed

(

void

)

const

Is there an unsaved change for this object or its children?

bool TAO_Notify::Topology_Object::is_persistent

(

void

)

const [protected, 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 in TAO_Notify_EventChannelFactory.

Topology_Object * TAO_Notify::Topology_Object::load_child	(	const ACE_CString &	type,
		CORBA::Long	id,
		const 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 in TAO_Notify_EventChannelFactory, TAO_Notify_Proxy, TAO_Notify_ETCL_Filter, TAO_Notify_EventChannel, TAO_Notify_Admin, TAO_Notify::Reconnection_Registry, TAO_Notify_EventTypeSeq, TAO_Notify_ETCL_FilterFactory, TAO_Notify_FilterAdmin, TAO_Notify_ConsumerAdmin, TAO_Notify_SupplierAdmin, and TAO_Notify_Constraint_Expr.

bool TAO_Notify::Topology_Object::self_change

(

void

)

[protected]

Method to report change in this object.

see also Topology_Parent::child_change ()

Returns:

false if save will never happen

bool TAO_Notify::Topology_Object::send_change

(

void

)

[protected]

Handle details of propagating change.

Returns:

false if save will never happen

bool TAO_Notify::Topology_Object::send_deletion_change

(

void

)

[protected]

Handle details of propagating change for a deleted object.

Returns:

false if save will never happen

Topology_Parent * TAO_Notify::Topology_Object::topology_parent

(

)

const [protected]

pointer to our topological parent

Returns:

0 if none
