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

◆ Topology_Object()

TAO_Notify::Topology_Object::Topology_Object ( )

The constructor.

◆ ~Topology_Object()

TAO_Notify::Topology_Object::~Topology_Object ( )

virtual

The destructor.

Member Function Documentation

◆ change_to_parent()

bool TAO_Notify::Topology_Object::change_to_parent ( )

privatevirtual

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.

◆ get_id()

TAO_Notify_Object::ID TAO_Notify::Topology_Object::get_id ( ) 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_EventChannel, and TAO_Notify_EventChannelFactory.

◆ get_id_path()

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.

◆ initialize()

void TAO_Notify::Topology_Object::initialize ( Topology_Parent * topology_parent )

virtual

Init this object with data from <rhs>.

◆ is_changed()

bool TAO_Notify::Topology_Object::is_changed ( ) const

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

◆ is_persistent()

bool TAO_Notify::Topology_Object::is_persistent ( ) const

protectedvirtual

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.

◆ load_child()

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::Reconnection_Registry, TAO_Notify_Admin, TAO_Notify_ConsumerAdmin, TAO_Notify_Constraint_Expr, TAO_Notify_ETCL_Filter, TAO_Notify_ETCL_FilterFactory, TAO_Notify_EventChannel, TAO_Notify_EventChannelFactory, TAO_Notify_EventTypeSeq, TAO_Notify_FilterAdmin, TAO_Notify_Proxy, and TAO_Notify_SupplierAdmin.

◆ self_change()

bool TAO_Notify::Topology_Object::self_change ( )

protected

Method to report change in this object.

Returns: false if save will never happen

◆ send_change()

bool TAO_Notify::Topology_Object::send_change ( )

protected

Handle details of propagating change.

Returns: false if save will never happen

◆ send_deletion_change()

bool TAO_Notify::Topology_Object::send_deletion_change ( )

protected

Handle details of propagating change for a deleted object.

Returns: false if save will never happen

◆ topology_parent()

Topology_Parent * TAO_Notify::Topology_Object::topology_parent ( ) const

protected

pointer to our topological parent

Returns: 0 if none

Member Data Documentation

◆ children_changed_

bool TAO_Notify::Topology_Object::children_changed_

protected

true of any of this object's children changed since last save_persistent

◆ self_changed_

bool TAO_Notify::Topology_Object::self_changed_

protected

true if this object changed since last save_persistent

◆ topology_parent_

Topology_Parent* TAO_Notify::Topology_Object::topology_parent_

protected

A safely-typed copy of parent_;.
