Each published line list record is an instance of the LLALineListRecord class definition.
LLALineListRecord realizes a significant number of interface definitions. In this set of interface definitions, ILineListRecord is the only interface definition unique to the line list record.
The line list record published by the line list application can be retrieved by another application, and then re-published as an object for a different class definition. For this reason, the line list record is tied to a SharedLineListRecord shared object definition.
