Member Function Documentation

void TAO_Notify_Constraint_Expr::load_attrs ( const TAO_Notify::NVPList attrs)

Load our attributes. Each derived type should call the superclass load first before loading its own attributes.

Reimplemented from TAO_Notify_Object.

TAO_Notify::Topology_Object * TAO_Notify_Constraint_Expr::load_child ( const ACE_CString type,
CORBA::Long  id,
const TAO_Notify::NVPList attrs 

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_Constraint_Expr::release ( void  )

Release this object.

Implements TAO_Notify_Refcountable.

void TAO_Notify_Constraint_Expr::save_persistent ( TAO_Notify::Topology_Saver saver)

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.
