Specialization

A derived entity specializes Component Entity in the following ways:

  • It references a Modeled Entity.

  • It initially inherits its properties and code containers from the Modeled Entity. Changes in the Modeled Entity are applied to the derived entity when the Component is compiled, unless the property or code has been changed in the Component.

  • The fields of the Modeled Entity are not inherited—they can be explicitly added as Component Fields.
