Member Function Documentation

void TAO_Notify::Topology_Savable::reconnect ACE_ENV_SINGLE_ARG_DECL_NOT_USED   )  [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.

virtual void TAO_Notify::Topology_Savable::save_persistent Topology_Saver &saver  ACE_ENV_ARG_DECL  )  [pure 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 ACE_ENV_ARG_PARAMETER); ACE_CHECK; for all children { if (want_all_children || child.is_changed()) { child.save_persistent(saver ACE_ENV_ARG_PARAMETER); ACE_CHECK; } } for all deleted children { saver.delete_child(child_type, child_id); } saver.end_object(this->id(), type ACE_ENV_ARG_PARAMETER); )

Implemented in TAO_Notify_Admin, TAO_Notify_EventChannel, TAO_Notify_EventChannelFactory, TAO_Notify_EventType, TAO_Notify_EventTypeSeq, TAO_Notify_FilterAdmin, TAO_Notify_Proxy, and TAO_Notify::Reconnection_Registry.
