org.dmlite.model.Entity

Entity abstract class to implement common characteristics of all concepts.

Each entity has oid and code properties. The oid property is generated by dmLite. The oid property cannot be configured. If you do not want to use the code property, do not configure it.

An entity may have a user defined id that can be simple or composite. It may contain propertie and/or neighbors. The id is configure by marking properties and/or neighbors with the unique configuration element set to true.
