| <p><strong><br /><span class="refsubsect">Usage</span></strong></p> |
| <p>You can specify <code>@Property</code> on a mapped attribute (or its <code>get</code>/<code>set</code> method) within an Entity, MappedSuperclass, or Embeddable class. You can also specify this annotation on an Entity, MappedSuperclass, or Embeddable class.</p> |
| <p>Properties defined in MappedSuperclass are passed to all inheriting Entities and MappedSuperclasses. In case of a conflict, property values defined directly on a class always override values inherited from a class's parent.</p> |
| <p>When using an <code>orm.xml</code> mapping file, EclipseLink ignores <code>@Property</code> and <code>@Properties</code> annotations on mapped attributes; annotations on classes are merged with those specified i the <code>orm.xml</code> file, with the latter taking precedence in case of conflicts.</p> |
