Abstract
Component connections are preserved during destructive component operations. Upon receiving a notification of the destruction of a direct component connection, a direct component connection is converted to an implied component connection. The implied component connection may be specified as additional component attributes of one or both components associated with the direct component connection or as data external to the component data structures. This allows preservation of the component connection despite destructive component operations. Upon the creation of a component, it is determined if the newly created component corresponds with a previously destroyed component that was associated with a direct connection. If the newly created component corresponds with this previously destroyed component, a direct component connection is created for the newly created component as specified by the implied component connection. Component connections can be recreated upon loading or instantiating components or upon accessing a component via a revision control system.
