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 (   )  [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 (   )  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.

void TAO_Notify::Topology_Object::get_id_path (  IdVec &  id_path  )  const

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

virtual void TAO_Notify::Topology_Object::initialize (  Topology_Parent *  topology_parent  )  [virtual]

Init this object with data from <rhs>.

ACE_INLINE bool TAO_Notify::Topology_Object::is_changed (   )  const

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

bool TAO_Notify::Topology_Object::is_persistent (   )  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 &  , CORBA::Long  , const NVPList &  ACE_ENV_ARG_DECL_NOT_USED )  [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.

bool TAO_Notify::Topology_Object::self_change (   )  [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 (   )  [protected]

Handle details of propagating change. 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
