Element (UML)
open-in-new
<p>In <a href="/facts/Unified_Modeling_Language/3tlNS0tH">Unified Modeling Language</a> (UML) 2.5.1, an Element is "a constituent of a model. As such, it has the capability of owning other Elements." </p><p>In <a href="/facts/Unified_Modeling_Language/3tlNS0tH">UML</a> 2.4.1, an element is an abstract class with no superclass. It is used as the superclass or base class, as known by object-oriented programmers, for all the metaclasses in the UML infrastructure library. All other elements in the UML inherit, directly or indirectly from Element. An Element has a derived composition association to itself to support the general capability for elements to own other elements. As such, it has no additional attributes as part of its specification. </p>
